Hello gary823

Thank you for choosing fixya.com.

First things first: I suggest taking your truck to a mechanic or an auto parts store that can do a diagnostics test done. If any fuses or relays are blown, this test should bring up any codes that would indicate any type of malfunctions.

The shift lever being locked: In newer vechicles, the brake pedel, as you know must be pressed in order for the transmission to be put into gear. There should be a sensor on the transmission that runs in cahoots with the brakes. This sensor tells the computer what gear the transmission is in. It is very possible that at the last time you put the vehicle in Park, that the switch had it's final moment of ability. If the sensor is in fact useless, it may be the reason the transmission is locked into Park. It may be the reason why the brake lights aren't working; and why the brake lights fuse is blowing. Also, check all relays, (can be tested with a fuse tester) and make sure all relays are good as well. Make sure also that the light sockets for the brake lights, tail lights, back up lights, and front running and blinker lights are in good condition. One faulty socket, can cause more than one bulb to blow, or cause fuses and relays to blow as well. Follow the wiring for the brake lights for as far as you can to ensure there is no damage (melted, broken, etc.). This could also affect fuses. This truck I see is barely 5 years old, but you'd be surprised how quickly parts and wiring and such will go bad, or wear out and/or just quit working.

If the transmission sensor is not the problem, and all fuses and relays are good. tranny fluid is full, check the linkage under the truck. It may be jammed somehow, or stuck. On the transmission, where the lever inserts, there is a seal - inside that seal, there is like a gear that the lever pushes in order to shift from gear to gear etc. You may need to have that checked out to make sure it's not broken inside. If your fluid is low, or empty, you may have froze up your transmission, however, you most likely would have been seeing large amounts of fluid in the frequent places you park. Another think to check is your differentials. Make sure the fluid is full in each, as well as the seals not leaking. The seal sits just inside the inner most part of the pumpkin (differential ball) where the yoke is inserted. Maybe you have just locked up the rear driveline. Check the seal on the front end of the driveline as well, (goes into the rear of the transmission (yoke). Check your U-Joints as well, making sure they are intact, tight. It may be a good idea to have them replaced if they look supsicous in any way.

These are all the things I can think of that would make your truck be stuck in park, and make your lights not work, and blow fuses.

I sincerely hope this information is useful and aides in the successful repair of your truck. Thank you again for choosing fixya.com. Please let me know if I can be of further assistance, or if you have any more questions or concerns (comments).

Thank you again,

2011 Nissan Titan heater/ac fan blows on high we replaced the VBC it did not fix it, now what?


What is VBC? Ah, probably Variable Blower Control? my guess you got wires crossed, or a short around the control or even direct short to hot (12vdc) wire. Double check your work, wire connections. Instructions? with the new? double check.

Why is my 2005 Nissan Titan overheating in traffic?


Check to be sure that the fan shroud is intact in order to allow the fan to properly draw air through the radiator. Ensure that the radiator and A/C condenser cores are not clogged up with debris that can impede air flow. If these are all okay, you may need to replace the fan clutch as it may not be working correctly.

Air conditioning fan makes loud noise the faster you ru it.


Concerning your broken vent -- this can be caused by a broken linkage or a malfunctioning servo motor as well. these vent have air ducts the sway back and forth to adjust the dual air flow function. if the servo o linkages are malfunctioning or not connected for some reason, it will not allow total control of the air flow and temperature range. Now, if you have a combination of a flow error and temperature error as well, thai can be caused by a combination of the two.

In this case, you will need to inspect the linkages as well as the servo motor function as well. in addition, i would test the air temp sensors for there operational value. they control the temp when you adjust the coll or hot function.

Concerning the Loud noise coming from the blower fan---

This issue can be caused by a misalignment within the blower housing or, it can also be caused by some minor damage within the motor itself, causing it to rotate in a erratic manner, in return, forcing it to rub against the housing itself. the best solution here is to extract this blower fan housing and inspect for lose fan propeller and motor stability. replace parts accordingly.

PLease rate and have a great day:)

I have the same problem with my windstar blower is fine but is coming cold air but no heat i dont know what to do can any one show me how to fix it thnx


First, feel the heater hoses going into the firewall under the hood. If they are hot, then you have hot engine coolant going into the heater core. If they are not hot, then you either have a bad thermostat or you are very low on engine coolant.

Next you need air flowing through the heater core so it can come out heated through your vents. If the iar is flowing somewhere else, your temp blend door is not moving because the bend door motor is bad or your temp knob on your heater controls is bad. The blend door motor is an electric motor.

------------------------------------------------
Air Flow Control
Air flow control is accomplished in the following manner:
  • Primary control is through the function selector knob , mounted on the heater function selector switch, which is part of the heater control .
  • The function selector knob has the following positions: OFF, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST and DEFROST.
  • The heater function selector switch combines a vacuum selector valve with an internal electrical switch.
  • The vacuum selector valve directs source vacuum to various vacuum control motors (18A318) . Refer to the System Airflow Schematic and Vacuum Control Charts.
  • An internal single-pole electrical switch is also controlled by the selector. The switch controls the electrical supply to the heater blower motor switch (18578) .
  • The position of the function selector knob determines the manner in which the system will operate.
  • Each position of the function selector knob is detented for positive engagement.
Temperature Control
The temperature control operates in the following manner:
  • Temperature control of the heater system is determined by the position of the temperature control knob (between COOL-BLUE and WARM-RED) of the heater control .
  • This control knob is connected to a potentiometer mounted in the heater control . This potentiometer is electrically connected to the electric blend door actuator that operates the A/C air temperature control door.

  • Movement of the control knob from COOL (Blue) to WARM (Red) causes a corresponding movement on the air temperature control door and determines the temperature that the system will maintain.
System uses a reheat method to provide conditioned air to the passenger compartment.
  • All airflow from the blower motor (18527) passes through the A/C evaporator housing .
  • Temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
  • Temperature blending is varied by the air temperature control door, which regulates the amount of air that flows through and/or around the heater core (18476) , where it is then mixed and distributed.

The ac won't work right


The first knob controls the temperature. Turning it counterclockwise will lower the temperature, clockwise will raise it. Pressing the button will turn on the circulate function (recirculates the air from the cabin).
The second knob controls the fan speed. Counterclockwise will reduce the fan speed, clockwise will increase it. Pressing the button activates the A/C compressor (allows colder temperatures).
The third knob controls the flow direction. Each picture indicates where the flow will go. Pressing the button activates the rear defoggers (in some models, it will also activate the heated side mirrors).
