Why is my climate control panel not working?
You will need to reprogram the new module to the vehicle order, you will need a scanner with this function. If you do not have 12V move your black lead from pin 8 and put it on a known good ground. If you now have 12V then you have a ground issue. If you don’t have 12V power supply wiring issue.

Instead, we just grab a test light and look at the voltages on each fuse. All of the smaller spade-type fuses have two tiny holes on top for test points. Turn on the ignition switch and turn on any systems you can that are related to the problem, then check for those two voltages on each fuse.
Why is the ground pin on my climate control not working?
If you have total loss of power to the unit, why not test the ground pin on the harness attached to the climate control with an ohmmeter. Im not 100% for sure on the ISX50, but I’m willing to bet the ground wire is a white w/black stripe and is not switched to ground.

Why is the AC panel on my car not working?
The blower comes on but no ac or lights. The dealer says I just need a new panel. He also says that the reason the car overheated is because of the ac dash controls failing. This seems very odd but I’m going to buy a used one and see if the ac and radiator fan start to work again.

Why are half of the Lights Out on my climate control?
Half of the lights are out on the climate control area. If GM knows this is an issue (there is a recall on vehicles 2006 and newer) they should be including the 2005 model as well. Radio, power windows, heated seats, and various gauges all stopped working at once while driving.
What kind of light do I need for my climate control?
Best is to use a test light. If you use a digital voltmeter, the module should be connected to get more accurate readings. Terminal 2 is a purple wire and must have 12 volts all the time. Terminal 16 is a purple / orange wire and must have 12 volts when the ignition switch is on.
Is there a light on the climate control?
All three of the climate control dials (fan speed, position, temp) have no light in the dark (do not illuminate when headlights are on). The green “o”n button works all of the time – when you turn A/C on, defrost, etc. There does not seem to be a problem with the controls alone, just no light. Adjusting the dim/brightness does not help.
