My 05 LGT just did this same thing... the HVAC and radio lights went out, but the radio and A/C still work. You just can't see what the settings are. Also, I noticed that when I pulled over and had the car idling, it started to fade a little bit, both the idle and the other dash lights. My wife said it happened to her once and she couldn't even start the car after she tried to restart it. I didn't believe her! Now, I see what she is talking about... are we sure it is the radio, and not an alternator or something?

 

Also, my CD player skips all the time, even on brand new CDs from the store.

I didn't have any problems with the dash lights fading or anything. The only reason I asked LittleBlueGT about his radio unit dimming or not was because when I lost control of my HVAC my radio didn't dim anymore when I turned on my headlights.

My problem gave no indications that it was the alternator malfunctioning. The problem was also solved when my radio and HVAC unit was replaced.

They replaced the radio/HVAC faceplate, not the guts of the radio itself.

 

 

Of course,after that didn't solve the probelm, they replaced the radio, and that didn't solve it either!!!!!!!!!

You should really tell them to just order a new unit and replace it. It sounds like you have the same exact problem I had. My HVAC display was completely dead but my radio worked fine. Does your radio display not dim anymore when you turn on your headlights?

Well I read this thread last year and it finally happened to me. Last week my HVAC controls were flickering on and off. When they were on I had full control of my AC. When they turned off I lost all controls but still had AC blowing. However this weekend while I was upstate I lost complete control of them. The HVAC display was totally gone and the AC was stuck on. I did a hard reset which turned the AC off. When I was driving home though I decided to try the AC and it turned on but a few seconds later the display just died. Throughout the whole ride the display would come back for a few seconds or so and then turn off.

 

I did notice something when my controls first completely died. Since it was nighttime I had my headlights on and I noticed that the radio display did not dim out with the rest of the displays. I'm pretty sure that it used to do it unless I'm imagining things. Well unless it comes back on tomorrow it's off to the dealer for me.

Well just got back from the dealer today and all is well again. They had to replace the whole unit to fix the problem. Took them awhile to get the part but I finally have control of my AC again.

Hoping for a TSB.

 

Anybody else there problem fixed? They replaced the HVAC controls, problem still there. Replaced radio, problem still there. Never replaced both at same time though?????????

 

Going on 3 months of no display, although it worked today for about 9 mins. 99% of the time for me it does not work.

LittleBlueGT how did they only replace the HVAC by itself and the radio by itself? The whole unit is integrated so they would have to replace the entire unit if there was a problem with one of them.

 

That might have been me. I dont know NJ roads for sh1t, I was on the way back or too Ikea.

 

I never get accused of driving slow. I gotta get the wife on here to read that!!

 

 

Yesterday around 6 pm on West side highway I saw a silver Kolb GtX special sedan with stuffed animals on the parcel shelf. A woman was driving. Sound like anyone's wife?

GCP is in NY though...?

Indeed I do.
