05 GXP major HUD issues
 

Hello everyone--just purchased a 2005 GXP last week and as my husband was driving it home the HUD quit working along with the heater,heated seats and A/C and calibrate compass kept coming on. It has come back on but within 10 minutes everything will be off again, I about froze one night because it turned the a/c on and I was unable to shut it off--seems like it's all connected somehow? We talked to the guy we purchased it from and he had it in the shop before and they replaced the control panel for heat and things but it did not fix the issues. He had an extended warranty which is being transferred over but in the mean time I want to see if anyone else has the same issues and I can just tell them what to look at. Thanks in advance Amber

That bunch of stuff should be controlled by the DIM or Dash integration Module. That's kinda off the hip w/o looking it up, but I think that's where the likely issue lies

Thanks so much..I really love the HUD so when it goes out I am not happy :) It's the little things that make me happy lol

No need to hail the greatness of the HUD to me. GM didn't offer it in the Buick Regal, yet ...all the Regals I've driven for more than a week have had it installed. :thumbup2
