SOURCE: have 1990 audi 100,car won't turn over,have 12 volts,makes a click sound under back seat when I turn key

Sounds like a dead battery. Do the lights come on and radio work? Maybe the lights are dimmer than normal or the door is no longer dinging when opened. Also another way to tell when the battery is not getting any juice to the car.
You may be able to get the car started using jumper cables. I would take it to a parts store immediately and have them check it (almost always free).

One easy thing (which is free and a maintenance item) is to clean the battery terminals and cable terminals. These can get very corroded and actually cause the battery to stop charging when the car is running. They may just need a good cleaning and a jump. It might take care of it!

Probably not the starter, but also an outside chance (full disclosure).

Good luck!

Rear a/c controls won't turn on


Have you checked the setup feture for the rear a/c on the front panel of the MMI display. You can lock out the rear panel from there, also if you have child protect activated a lot of features in the rear compartment are disabled.

How to retrieve DTC:
The heater control panel has self-diagnosis function. To run the self-diagnosis function, do the following:
1.Turn the blower fan OFF.
2.Press and hold the recirculation control switch and the rear window defogger switch down.
3.Turn the ignition switch ON (ll).
4.Release both switches. The recirculation indicator and the rear window defogger indicators come on. The recirculation indicator goes off 3 seconds later and the A/C indicator comes on, then the self-diagnosis will begin. About 10 seconds later, the self-diagnosis will finish and the A/C indicator goes off.
- If any trouble is found, the recirculation indicator blinks the diagnostic trouble code (DTC) to indicate a faulty circuit or component.
- If the system is ok, the recirculation indicator stays off.

Temperature knobs won't change temperature Chevy Tahoe


You likely have a HVAC control head failure. The rear heater problem is likely a door actuator, the rear wiper is likely a open wire in the door jamb in the top. The gauges are likely a cluster failure.

GENERAL PROCEDURES Rear Window Motor Initialization s1r~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Make sure that no obstructions are present in the power rear window system when carrying out this procedure.
NOTE: This procedure must be carried out when repairs are performed on any part of the power rear window system including when: the power rear window motor is removed from the window regulator drum housing, a new power rear motor is installed, a new power rear window regulator is installed, a new power rear window module is installed, and any operation in which grease or lubricants are applied to the power rear window system.
NOTE: All power rear window components (window glass module, window regulator, window motor, and glass runs) must be installed and torqued to specification before carrying out this procedure.
NOTE: Steps 1-6 must be completed within 30 seconds. The entire procedure must be completed within five minutes.
NOTE: Once the ignition key is turned to the ON position in Step 6, it must remain on until the entire procedure is completed.
NOTE: Steps 7 and 9 require that the power rear window control switch be held in the closed position until the power rear window motor stalls the window in the upper header seal. Step 8 requires that the window control switch be momentarily turned to the open position.
  1. Start with the ignition in the OFF position.
  1. Turn the ignition to the ON position.
  1. Press the power rear window control switch vent button six times.
  1. Turn the ignition to the OFF position.
  1. Press the power rear window control switch vent button six times.
  1. Turn the ignition to the ON position. The power rear window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has entered initialized mode.
  1. Rotate and hold the power rear window control switch to the closed position until the window stalls in the upper header seal.
  1. Momentarily rotate the power rear window control switch to the open position and release. The power rear window will carry out a one-touch down operation until the window stalls at the bottom of the travel stop designed into the window regulator.
  1. Rotate and hold the power rear window control switch to the closed position until the window stalls into the upper header seal. Once this operation is complete, the window will move up-down-up-down approximately 20 mm (0.8 in). This movement indicates that the power rear window motor has been successfully initialized.
  1. Verify correct operation of the power rear window by moving the window to the fully open, vent, then fully closed positions.

I have a 1998 Plymouth voyager and the climate control lights are flashing. I ran a test i found on the internet and got it down to two lights flashing(the ac and the recirculate). I got it to where the...


OK got your message on the other post (About the van) I am assuming that your Voyager is equipped with Automatic Climate Control. Follow the instructions below and you will get a better idea of what is wrong with your system.

Calibration/Diagnostics
1. To enter calibration/diagnostics test, set parking brake. Start and warm engine to normal operating temperature. With engine idling, turn blower switch to high. Turn mode switch to panel. Open all outlets. Move temperature to full cold.
2. Press and hold rear wash and rear wiper buttons simultaneously for 5 seconds (Until ALL LEDs illuminate). All LEDs should illuminate for 5 seconds. Rear wiper and intermittent rear wiper button LEDs will flash alternately during calibration/diagnostics test.
3. After approximately 60 seconds, if only the rear wiper button LED is flashing, calibration is successful and the system is okay. If rear wiper and intermittent rear wiper button LEDs are flashing, Diagnostic Trouble Codes (DTCs) are present. (See "Reading Diagnostic Codes" below)
4. To exit calibration/diagnostics test at any time, press the rear window defogger button, rear wiper button, or cycle the ignition off and then on. Test will automatically terminate 15 minutes after calibration/diagnostics is entered.

Reading Diagnostic Codes
1. Perform calibration/diagnostics test. If a DTC is present after calibration/diagnostics test has been performed, system will flash rear wiper and intermittent rear wiper button LEDs in sequence. Rear wiper represents code level, and intermittent rear wiper button LED represents code value.
2. Each time the rear wash button is depressed, rear wiper button LED wil cycle to the next code level in numeric sequence. After code level 5 is reached, rear wiper button LED will cycle back to code level 1. See table below.

2005 RX8 heater is blowing cold air. Fluids are topped up.


You need to repair the heater core with a soldering gun.

If you do not have heat, or only have heat, IMHO it is most likey the AC/heater control unit. This is the part which has the AC/heat control buttons and knobs.

Easy Diagnosis:
The easiest way to verify this is to turn on the radio, press and hold the power on/off button and press and hold the scan-up button for a second (full second). The word "A/C TEMP" should appear on the left of the display and a number from 0 to 16 on the right. I suspect yours will have the number 0 (or 16 if heating only problem) displayed no matter where you turn the temperature control knob. If this is the case you could turn the temp. knob to full heat and see if it goes to 16 after pushing down or to the right on the knob.
In a working system, the number moves evenly in increments of 1, from 0 to 16 as you turn the temperature knob.

Easy Fix:
I was able to take mine out and solder 3 loose connections to fix it.

The beginning steps are the same as for any radio removal procedure and check for loose connections.

The air conditioner control lights on dash bord keep flashing off and on


Try this and see if it works. Let me know.
Start your van. Then slide your temp lever all the way to the left (full cold). Then turn the Mode Control to 'panel' (the one that sends air to your face only). Then turn the 'blower switch' to all the way to full. Now go to the leftmost three buttons. Press the top one (rear wiper on constant) and the bottom one (rear wiper washer fluid). Hold these two for a few seconds. Once the lights come on solid then begin to flash you can let go. The AC will now calibrate. You will feel the air blow out of all the different zones at different intervals and see lights come on and go off. Then after a minute or two the top button you pressed will be slowly flashing. This means it has been completed . Press the last flashing button and you are done.

AC & Rear wiper switch button indicator lights blink


The procedure for re-setting the HVAC control panel on a 1998 Dodge Grand Caravan follows:
With ignition on but not running
1. turn knob to air vents
2. turn fan knob to ON
3. temperature setting on COLD (2X) {I have dual temp controls}
4. hold top(rear wiper) and bottom (rear wiper with wash) buttons pressing down together until all the buttons cycle through (this will require 1 to 2 minutes of continuous pressing)
I learned this from a very helpful local Dodge service adviser

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).
