Windows not working correctly?

Hello,

I can no longer control my rear power windows. I want to replace one because it will not stay up. How do I know if it is the window motor or the window regulator that needs to be replaced?

My electric driver's window is moving very slow, how do I fix this?

Thank you

Window goes almost half way down and then stops and seems to slip off track. I have to manually grab and pull up then window moves up automatically again.

If I were you I would get a Haynes manual from ebay or Alibris for 4-10 dollars, it is very helpful to have the repair manual.

The window buttons stopped working after the driver side sparked from a cut line, neither button works. We got a new button from a grand prix but we cant find the wiring diagram for either of the cars.

Yes, they seemed fine

I have a 2 door and no I don't have one.

Ugh. Yes, I am getting this car so that it is ready to sell.

Okay, are there any good instructions online on how to fix a window regulator? I have pretty much decided that is what my mechanics broke. They wouldn't take responsibility for being careless with my fragile crank window. Instructions? I have a manual but it really isn't much help.

My AC seems to be low on r134a since it has not been blowing much of any cold air. Late in the season to be worrying about this, but you know how it is. Living down south, you'd be insane not to have AC. How do I know if it is just low on refrigerant and not something more costly? The compressor looks like it is running and it is blowing out cold air but not much. Of course, I have stopped using the AC when I noticed that it wasn't producing any cold air.

Also. The biggest question of all since I do not have a cause pinpointed and it is kind of important now that colder weather is coming. My vents won't switch from the regular vents to the windshield defrosters. What could be causing this?

Oh, and as I specified in the title. My car is a 1995 Grand Am SE Coupe with almost 88k miles (yes, you read right). I don't know the engine size and I really doubt it matters with my question.

Lizzy :)

My experience is with my wife's 93 Grand Am SE, 130K miles.

I'm not sure what manual you have, but I found a Chilton's manual (the vehicle specific, $20 variety, similar to the Haynes manuals sold at Auto Zone, but I think the Chilton's are more helpful) to be very helpful. If it is a manual crank window I can help with more specific instructions as I have done this job before.

I would recommend going ahead and recharging the refridgerant (make sure the vehicle does, in fact, use r134a and not the older R12, I can't remember when this switch was made, but my 93 had the R12; R12 is incompatible with r134a). The refridgerant is cheap and easy to do yourself and the most likely culprit, relative to the other possibilities.

Any thoughts on the vent problem?

I know my refrigerant is r134a because it says so under the hood. It also says it holds 2.25lbs of it. ;)

What other parts will I need to fix my window other than a new regulator? I'm about to order a new one so I want to be sure what else I should add to my cart.
