My 2004 Saturn Vue air conditioner no longer works well when the vehicle is at idle RPM (sitting or driving at low RPM). It doesn't get very cold or seem to pull any humidity out of the air. The freon charge is fine. Dealer tells me that compressor is leaking fluid, $1500 to replace compressor. Advice?

The compresor can be damaged from to much or to little gas..

I would have it checked..

all cars of that year use r-134 refrigerant. Follow the ac lines till you run across the service port. The one near the evaporator (front of engine) is the high side; leave that one alone. It usually is marked with a red cap
the low side port is near the firewall, and usualy has a blue cap. The valve for a refill can usuallly will only fit on a low side. When filling the can will get very cold very fast. If the can doesnt start to get cold immediately, remove it you have it on the wrong side. Make sure to remove it immediately, as keeping it on the high side will pump liquid freon into the can causing it to explode.

Most likely it needs to have the freon recharged. This is very common with R134A systems. You can do this yourself or have a shop do. Doing it yourself requires that you locate the Low pressure line, don't worry, the recharge can adapters will only fit the low pressure side, and to follow the directions on the can and watch the attached gauge. Over charging your AC is very bad and can cause very expensive damage. All the instructions you will need for using the recharge can will be printed on the can. Follow them. If you choose to do the job yourself you can get the recharge can with Hose and Gauge from Walmart, Auto Zone or just about any places you can get Oil, plugs and Oil Filters at.
