1st you must get a recharge kit from your local parts store, the R134 kit comes with a can of refrigerant and a gauge attached to a line and a female fitting that hooks to the cars AC charging port, the fitting goes on the charging port of the AC low side, if u go to the link below you will see very good instructions with pictures, the car in the picture is a typical GM car AC system, I have no idea how low your system is, so one can may not do it, when the reading on the gauge goes down to about 30 PSI the system is at full charge, if u use more than 1 can to get the reading down there u have a large leak and u are wasting your money until the leak is repaired, on this car the leak will require the AC compressor be replaced. here is the link to the web site i mentioned.

    the gauge attaches to the low side AC hose or the round can it goes to near the firewall which is called the "Accumulator", the low side line is the larger of the 2 lines from the AC compressor, di u look at the we link I sent it shows the the whole job with pictures please look, DO NOT BLEED THE SYSTEM DRY. the low side is the.

SOURCE: 2004 pontiac grand prix .... how can I tell if

at the bottom of mirror there is a square symbol with vertical lines that look like wriggling snakes, it is the same symbol used for the heated back glass.

It's under the hood, on the driver's side, under a square, black box with a lightning symbol on it. Loosen the flower-shaped screw that holds the lid of the box down, remove the lid, flip it upside down and when you look at the inside of the lid, you'll see a map of all your car's fuses. There's also a fuse diagram on the very end of the dash, but it's accessible only when you open the driver's side door. When you're driving, that end of the dash is blocked by the closed door.

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.

It would be the fuse for the fans or they don't work at all. And you would need to recharge the freon too. Hope this helps!?

2000 pontiac grand prix ac problem

If the compressor is working, a mechanic would check the low and high gauge pressure.
The freon has to flow thru the system to work, and the cooling fan draws air thru the condenser to get rid of the heat from inside the car.
If the ac clutch is working but the gauges show equal pressure, the compressor may be faulty.

A/C works fine, just doesn't blow cold air anymore.

If it works fine you probably just need to have your ac recharged.
