Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to Just Answer!
Are you talking about the button illumination for night time driving or the digital display not turning on?
Do you have a test light and are able to test a few things?
Do you have a digital multimeter or a voltmeter?
I need you to remove the fuse box cover from the left side of the dash, then turn the key on and test both sides of fuse #17 and #19 to see if you have power on both sides of the fuse. You should have battery voltage on both sides of the fuse. Let me know if you have voltage to both fuses and if they have power on both sides of the fuse.
Put your voltmeter black lead to a good ground and the red lead to the test port on the fuse.
Here is a picture of a test light testing fuses, you need to use your red test lead in place of the test light probe.
There is no accept button because I haven't sent you an answer yet, so check this out and we can go from there! I want to diagnose this first before I send an answer!
You could have a faulty a\c heater control head assembly, but I would like you to remove it so we can check for power and ground to the unit.
Can you remove the display unit from the dash so we can test for power and ground?
The center bezel around the control head will just pull rearward and the control will come with it. The center bezel has a bunch of clips holding it to the instrument panel and if you pry the bezel out the clips will release.
If your meter quit, we will have to get a test light! Can you get one from your neighbor?
went over and neighbor is not home I will have to purchase on myself if you could tel me where to test on the panel that would be more then helpful
I need you to disconnect the control head connector and turn the key on. Then hook your test light lead to a good ground and probe the white wire and the pink wire to see if you have power to both wires. If you have power, I need you to take a small paper clip and push one end of it into the pink wire terminal. Then hook you test light lead to the paper clip and probe the two black wires to see if the light illuminates bright. This is checking the ground to the control head. When hooking the test light exactly as I mentioned the light should illuminate bright and if all of them do, you must have a faulty control head(display unit).
Let me know and we can go from there!
You are very welcome!
