I'm thinking of lowering my 2004 grand prix GPT super charge. And I'll like to see how it will look before I do it.

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!

SOURCE: charging system failure

Hello! The problem you are experiencing is most likely due to a fautly or malfunctioning alternator. You can take the car to any major auto parts store, and they can do a FREE charging system test which will tell you if your alternator is operating (and charging the battery) properly, as well as if your battery is accepting the incoming charge from the alternator.

Hope this helps and good luck!

SOURCE: my 2004 pontiac grand prix window it will go down

Does it try to come up, EG is there power being applied when you press the UP switch? if it makes no sound or movement when pressing the UP switch it is probably a worn out switch - available at Pontiac dealers though you may have to order it and wait a few days - have your VIN number for the parts desk and you'll get the part in no time - the switch levers out of the panel - use a plastic tool if possible to prize the switch out so you don't damage the surrounding trim - the cable connector clips off the old switch and goes on the new switch, press the switch home into the recess and jiggle it a bit to make it dead flat - window should work now.
If it IS making an effort to come up then either you have a poor earth or power connection making it so there is not enough power to pull the windows up (which is harder than down due to the weight of the window) -- check the cabling behind the door panel, and as above pull out the switch and check its connector too.
OR... the window is out of alignment and is jamming - putting it back in alignment means taking off the door panel and getting at the bottom of the window runner, loosening the bolt(s) on the bottom of the runner and moving it sideways so it hold the window steady but not tightly, you may have to try having it tighter or looser against the window till you get the best performance - also oil the moving parts/cables of the window mechanism (dont get oil on the glass, it will smear for weeks) to give the best chance of smooth operation.

The lowside port is located by the firewall next to the brake booster and the highside is located next to the air filter box towards the bottom.
