97 Nissan quest wont start red security light blinking


The Security Indicator Light illuminates to indicate that the security system is either working properly or to let you know that there is a fault in the system.
If the Security Indicator Light is flashing with the key out of the ignition lock and accessory position, this is a normal sign that the alarm and the immobilizer system is active.
While starting the car or key in the "run" position, the security lamp should illuminate briefly then go out. This a "bulb check" and is also normal.
If the Security Indicator Light is on steady with the key in the "run" position, and the vehicle won't start, there could be a fault with the system. In this case, the first thing to try is a different key to see if this starts the vehicle. If it starts, the key is faulty or the system has a problem with that key. If you are still getting a no-start with the light on steady, the system is at fault and will need to be inspected.

Why aren't lights for center console on the shifter working?


Could have a wiring problem , a wiring pin backed out of a connector ! If you don't know about automotive electrical an wiring diagrams an electrical wiring trouble shooting I suggest you take it to a ASE certified repair shop .
Instrument Cluster and Panel Illumination The instrument cluster and panel illumination is used to provide backlighting to the instrument panel, switches, and control components when the headlamp switch is in either the PARKING LAMPS ON or HEADLAMPS ON position. The level of intensity is adjustable by pushing the instrument panel dimmer switch either up to increase intensity or down to decrease intensity.
The dimmable backlighting components are:
  • Instrument cluster
  • Hazard switch
  • Rear defroster switch
  • Message center switches
  • Parking aid switch (if equipped)
  • Transmission range selector
  • Fog lamp switch
The non-dimmable backlighting components are:
  • Driver front door lock and power window control switch
  • Passenger front door lock and power window control switch
  • Driver rear door power window control switch
  • Passenger rear door power window control switch
Principles of Operation
The instrument cluster sends a signal to the instrument panel dimmer switch. The instrument cluster provides a variable pulse width modulated (PWM) signal to the dimmable backlighting components in accordance with the position of the instrument panel dimmer switch.
  1. Verify the customer concern.
  1. Visually inspect the following for obvious signs of mechanical or electrical damage.

    Visual Inspection Chart Mechanical Electrical
    • Instrument panel dimmer switch
    • Smart junction box (SJB) fuse(s):
      • 7 (10A)
      • 15 (30A)
    • Circuitry
    • Illumination bulbs
    • Instrument cluster
    • SJB
    1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
    1. NOTE: Make sure to use the latest scan tool release software.
      If the cause is not visually evident, connect the scan tool to the data link connector (DLC).
    1. NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM.
      If the scan tool does not communicate with the VCM:
      • Check the VCM connection to the vehicle.
      • Check the scan tool connection to the VCM.
      • Refer to Section 418-00 , No Power To The Scan Tool, to diagnose no communication with the scan tool.
    1. If the scan tool does not communicate with the vehicle:
      • Verify the ignition key is in the ON position.
      • Verify the scan tool operation with a known good vehicle.
      • Refer to Section 418-00 to diagnose no response from the powertrain control module (PCM).
    1. Carry out the network test.
      • If the scan tool responds with no communication for one or more modules, refer to Section 418-00 .
      • If the network test passes, retrieve and record the continuous memory DTCs.
    1. Clear the continuous DTCs and carry out the self-test diagnostics for the instrument cluster.
    1. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index. For all other DTCs, refer to Section 419-10 .
    1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .
Symptom Chart Condition Possible Sources Action
  • One or more module-controlled illumination source(s) is inoperative
  • Circuitry

  • Go To Pinpoint Test A .
A2 CHECK VOLTAGE TO THE INOPERATIVE ILLUMINATION SOURCE
  • Key in OFF position.
  • Disconnect: Inoperative Illumination Source Connector.
  • Key in ON position.
  • Place the headlamp switch in the PARKING LAMPS ON position.
  • Measure the voltage between the inoperative illumination source, harness side and ground according to the following table:

    Illumination Source Connector- Pin Circuit Rear window defrost switch C2340-3 19 (LB/RD) Hazard flasher switch C2039-8 19 (LB/RD) Parking aid disable switch C2339-3 19 (LB/RD) Message center INFO switch C269a-3 19 (LB/RD) Message center SET switch C269b-3 19 (LB/RD) Transmission range selector C2096-4 19 (LB/RD) Fog lamp switch C2341-3 19 (LB/RD)
  • Is the voltage greater than 10 volts?

Heater only blows cod air even when engine is warm. changed thermostat. doesnt fog up ad smell like haeter core.


Your car's heater is a life saver in cold weather. Before attempting to repair your car heater, you should understand how your heater system works. First, on this page is an explanation of how the car heater system functions, further down the page are some pointers on heater system trouble-shooting. To warm the passenger cabin of your car, the heating system makes use of excess heat from the engine internal combustion process. A car's engine, in fact, when in operation produces so much excess heat that if the excess heat is not removed, it would destroy the engine. It is your car's cooling system that removes that dangerous excess heat. Some of the excess heat is released through the exhaust. Most of the excess heat is absorbed by a circulating liquid coolant, which is a mix of water and antifreeze. The heated liquid coolant is carried from the engine through hoses to the radiator, which transfers the heat from the coolant to the outside air. That heat transfer lowers the temperature of the liquid coolant, which is then circulated back to the engine to absorb excess heat again. Whereas the radiator is located at the car front grill, the unit that transfers heat to the passenger cabin is located inside the dashboard. This unit is something of a mini-radiator and is referred to as the heater core. Heated liquid coolant circulates through tubes in the heater core and a heater fan blowing across those tubes, as well as through little fins encasing the tubes, directs warm air through heating vents into the passenger cabin. Because your car's heating system works off of its cooling system, heating system malfunctions are often caused by problems in the cooling system. The heater core in your car is similar to the radiator in the front of your car; in fact it looks like a small radiator. The difference is the heater is mounted inside the car and air is blown through the fins of the core. The heater hoses transfer engine coolant from the engine to the heater core, this allows the heat from the engine coolant to be utilized and warm the passenger compartment. When a heater stops functioning determine what type of failure has occurred to execute a repair. We have listed the most common problems below:

Heater Core
Troubleshooting Procedure
  • Step 1: Check Engine Coolant Level - Most cars have coolant reservoirs with opaque white plastic tanks and measuring lines allowing you to see if the coolant is at the recommended level. Coolant expands when heated, and for that reason, most coolant reservoirs have a Full-Cold and a Full-Hot line. If there is too little coolant in the reservoir, you should be alerted to the possibility that there could be a leak somewhere in your car's cooling system. Remove the reservoir cap and add coolant to the Full-Cold line, if a very short time after you refill the coolant reservoir the coolant level is low, there is a leak in your car's cooling system. Engine coolant is used to heat the heater core and if the vehicle is low on coolant the heater core will stop working. The heater cannot produce heat due to the lack of heat from the engine coolant. Even if the engine is not over heating the coolant level can still be low. Inspect the engine coolant level in the coolant reservoir tank; coolant level should be between the hot and cold marks. Always check the coolant level when the vehicle is cold, preferably over night. Check for engine coolant leaks and repair as needed, then refill with coolant and recheck the system.

  • Step 2: Inspect Heater Control Valve - The heater control valve is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced. After the repair has been made refill the coolant level and recheck system.

    Heater Control Valve
  • Step 3: Check Vacuum Feed - Most heater systems are operated by engine vacuum. This vacuum is used to actuate servos to move the temperature adjustment doors inside the heater plenum. If engine vacuum is not present the heater will not operate properly. To test for this condition remove the vacuum feed line from one of the vacuum servos. With the vacuum feed line removed insert a vacuum test gauge. If no vacuum is present, open the hood and inspect all small vacuum lines from the engine to the firewall and repair as needed. If a hissing noise is present under the dash when the engine is running a vacuum leak exists and must be repaired to restore heater function.
  • Trouble Shoot Heater/Air Conditioner Blower Motor. An electrical motor is used to push air through the heater and air conditioner system. If this electric motor fails it will not force air through the system. Ground a test light lead to a good ground source, like a metal brace under the dash, seat mount bolt or under hood brace. Turn the key to the on position; check the fuse in the heater or blower motor fuse panel with a test light. Then lightly touch the service port at the top of the fuse on both sides. If the test light illuminates on both sides of the fuse, the fuse is ok and working properly. If the fuse lights the test light on one side it is blown and needs to be replaced. fuse_panel.jpg
    Power Distribution Center
    If you are unsure of the location of the heater fuse consult a repair manual. If the fuse condition is ok, position the blower speed to the highest setting. Connect the ground end of the test light to a known ground source. Then probe both ground and power feed wires of the fan motor. The test light should illuminate on only one of the wires (fan motor failed). If the test light illuminates on both wires the ground source has shorted. If neither of the wires illuminate the power source is shorted. To trouble shoot this style of problem a wiring schematic is needed.

Does anyone know where i COULD LOCATE a steady flow vacuum line on a 07 sebring


The vaccum assist brake booster gets a large steady flow of engine vacuum however I'm uncear the reasons you need this source and don't neccessarily recomend tapping into this line unless you need this source for diagnostic or other temporary reasons

Side mirror


You want it to be illuminated with the lights on, but still blink when you use the signal? That's probably going to be tough, since that would require an additional wire and a modified bulb socket, plus a bulb that is identical in dimensions to the bulb in there now, but which has two filaments (one for constant illumination, one for turn signal flash). I doubt you're going to find that, and will probably be restricted to using it only as a flasher, or only as a marker light.
