Question about 2007 Chrysler 300c AWD Sedan New Cars

2 Answers

I have a 2002 300M - recently the light display on the climate control panel (above the radio) went blank - no lights. After a few days the lights started working again. I had no further issues until last week the lights for the dash gauges did not work when the lights are turned on. The gauges have flourescent green light. The light on the center clock does work. The light switch is turned on to the proper position and the clock light dims and brightens with adjustment of the wheel by the light switch. This model has auto lights and they work properly. I have removed the light switch and the dash and cleaned the contacts and checked for any connection issues. This is not a minor task. Today the light display on the climate control panel failed to light. Now both the gauges and panel have no lighting. I have checked the fuses in the panel by the drivers door and the fuses in the engine compartment. What else should I look at or where should I look? Do I need to replace the instrument panel board, the light switch or look elsewhere?

    I surmised that one method is to trace the power - this is like finding a needle in a haystack. I was looking for more assistance like a wiring diagram or what is common between these two systems. Its hard to troubleshoot when you do not have a vision of what you are attacking.

    I appreciate the appoach given but the advice is no more than what I would do with limited information. Looking for lack of power on wires is a long process when I do not know which wires are providing power to the lights. I requested advise to narrow my troubleshooting search not to validate it.
    What wire colors should I be looking for from the switch to the dash? What is the power source - wire color to the switch?

There may be faulty relays or connections to the dash control board circuit. Check connections. You can easily pull out instrument cluster to access any wires. Most connections will be under the dash on drivers side.

Well get a voltmeter and if you have voltage running to the panels, then replace them, I bet you either have a bad ground or wiring issues though which are hard to track down. If there wasn't voltage there (make sure you have the car running when you check), the see if you have voltage at the fuses for those panels. From there you can determine where you are losing voltage which can be at many different places which makes it harder to track down, but hopefully the above will help you find the problem. Let me know how this turns out.

    Yes, sorry, complete wiring diagrams will be located in a Haynes or Chilton manual that can be purchased at any auto parts store for a relatively cheap price. Unfortunately I can post them here but overall the wiring is color coded and like I said before, if you have a volt meter and can track down the closest spot to the battery that doesn't get voltage to the controls, then that will help narrow down where the wiring is most likely broken.

Climate control blank


ahhh some one upgraded the cars security package and crossed the wires and or had a new sterio installed
trace the wireing back someone spliced into the wires to add these items
theres specific harnesses made for vehicles to add sterios no splicing at all

or you have a big rodent problem chewing wires
now the other thing is failing alternator reset codes and try again
all that you mentioned above is due to security feature built into your radio that controls most your vehicles functions do not drive in this condition till you get fixed very unsafe

Symptom is radio diplay or controls don't light up, Delco CD radio's and Bose preminum sound radio/CD players. Models all GM cars and trucks 1990's to presnt.
This problem is caused by two tiny burnt out bulbs behind the LCD display thay are soldered to the circuit board behind the radio LCD display and can be replaced, this requires the radio be removed and the housing taken off and the front display un-clipped, you will need a low temperature solder pencil and thin strand solder the bulbs are available from Radio Shack, the part number is 272-1092, this is a 2 pack of miniature 12 Volt 60Ma bulbs. This radio display bulb is used in may car models, this bulb also repairs climate control displays as well as other low light displays like switches

2003 Envoy intermittent display, radio, ac control, shift, comp.


This sounds like your alternator maybe going bad. When your alternator starts to go bad lights such as headlights, radio lights will go dim wipers will start to move slower but if you cut one of the things off such as the wipers the lights will get brighter for a few minutes then not long the car will shut completely down. Hope this helps.

2004 Saturn Vue hazard light button pushed into the dash


Same on my 2004 Vue. Pry up shift panel, use putty knifes, slot screew driver, then pry up outer panel (with power window switches). remove screws holding radio, climate control panel (I believe there were 4 screws). gently lift this panel up and push gently toward windshield to unlatch. Don't lift higher than is necessary to acess 4 way flasher switch as climate control cables shouldn't be pulled hard so as do damage to climate control panel. The catches broke on my 4 way switch so I used Goop (from Walmart, Lowes etc.) to glue it in switch recptical. After glue dries, latch panel, screw panel in place and snap widow switch and shif panels in place.
