Can i disengage the ac compressor on my pontiac monatna

you can disengage it by not turning the AC on in the vehicle. the AC is engage by the clutch once you turn the AC on in the vehicle. as far as removing the belt from the AC, you can only do that if there is only one belt going to the AC. If you have 1 continous serpentine belt, then no. unless you go to an auto parts store and get a new serpentine belt, but tell them there is no AC on the vehicle.

AC cycles on and off when car idles low.

The compressor should cycle on and off. Sounds like the idle needs to be set. There is a pressure sw. on the dryer that might be going bad but the plugs and wires will not cause your problem unless they are just really bad.

2003 trailblazer, ac not working (compressor not coming on nor the belts turning). The outside temp gauge says it is 3 degrees F when it is actually 90+. Is this a sensor switch problem?

Mine did this once. The entire AC control panel was dead as if it was disconnected.
I made it start work again by reseating the AC fuse in the fuse box under the back seat.
Go figure...

Where is the low side service port on a 2003 grand am (6cyl)

If your talking about the low side sevice port to charge your ac, its easy to find. With your recharge kit, it comes with a nozzle to attach to this lowside port. Each port, (lowside and highside), are different diameters. The charging nozzle will ONLY fit onto the lowside port. Just run the length of your ac lines from the compressor and trace them back to the firewall. You should find both ports before you hit the firewall.
