Air conditioner service port

Where do I find the service port for the air conditioner on a 97 grand am?

Look for the blue cap on the line coming from the compressor. It should be at the top near the radiator. If your ac is charged at all, the line will get cold. avoid the hot one, its the high pressure line and it can blow the bottom off a can of 134-a and cause serious injury to anyone in the area.

4 or 6 cyl???

My 6 Cyl has it below in front... you have to get at it from under the car up in around the middle of the Rad. Just by the Compressor.

Can't say for a 4 tho...

My red cap (high pressure) is right on top but I can't find the blue one . The compresser is all but completely out of sight, Me and two other guys looked over and under everywhere. We even took a plastic panel from the passenger side wheel well where the low side was headed, but no luck. I can't believe GM would hide this so well. Mark Of Excellence my foot!!!

the service on my 95 with a quad 4 is on the back of the compressor, you can reach it but if you have really large arms expect them to get a little warm.. i was looking at a 96 in the junkyard yesterday, the service port on that one was on the top by the radiator, and it had the 2.4 quad4
