2001 Grand Prix. At times, HUD will not come on. When it doesn’t, heat and AC will not operate. How to fix?

SOURCE: 2005 grand prix HUD can only be seen when i look below steering..

I have a 2004 Grand Prix GTP with the hud. Mine doesn't work either, but I think I've narrowed it down to the motor inside which powers the mirror. My switch works fine as I can see the light from the hud when i look really low aka in line with the steering wheel. I believe either something has been disconnected or else the motor gave out. In order to fix this the dash will need to be torn apart. I didn't get an estimate because I will probably do this myself as I'm a mechanic. Hope this helps you!

There is a spring inside the HUD and it has probably come off. The samething happened to mine. I had to take it out myself and fix it. Majorhassle. The dealer wanted over 600.00 to do the same.

SOURCE: how much to change a oil pan gasket for 2001 grand prix 3.8 gt

If you want to repair the oil pan I would also check lower engine mount for leaking oil and cracks in anti sway bar near fitting's. This due to engine mount is oil filled. OEM sway bar is made of tubular steel and they crack easy. Replacement sway bar is solid steel. Here's the kicker. When they pull the lower frame to service oil pan. The engine mount and sway bar are attached to that frame. A honest mechanic should only charge for parts ($35 for mount and $100 for sway bar) and maybe a extra hour. My mechanic did all in 5 hours. FYI gasket is only $35 bucks. Good luck

SOURCE: 2001 Grand Prix: can't find the blower motor resistor on 2001 Grand...

Under the passenger side of the dashboard is a carpeted cover you'll need to remove. Once that's out of the way you'll see the blower motor on the RH side and just to the left of it right next to the frontwall is the blower motor resistor held in by two screws.
Here's a picture of the old design (right) versus the new design (left).
