2000 model, A/C compr. wont run

The compressor won't come on. The car has 27k miles and the system is charged. Fuses are good. ???????

How about the relay? Or the low pressure switch? Is it full of refrigerant??

[hanssolo]

The owners manual shows no relays for the compressor. There is charge but I need adapters for my gauges to see how much. They keep changing the fittings every 5 yrs. - that does'nt help. I'll also put voltmeter on the compr. plug & check that.

See if this diagram helps you any.

Thanx Hillbilly, good diagram- I printed it. Also found site with owners manuals in Adobe. Anyway I got can of freon with a gauge in the hose and after dumping some in, the compr. clicked on so its real low. My next question is: can I charge in the drier/accum fitting? Its all I see on the low side for a fitting. The hi & low side valves had some pressure still so I don't believe theres any air in the system. How many ounces does this system hold?

Good deal solo. Your system takes 2 pounds 6 ounces if it is completely empty. I would use a thermometer to measure duct temperature and when it gets around 40 degrees F stop adding refrigerant. You need to add a little at a time and let it run a few minutes in between shots and moniter the temperature at the vents. The fitting at the accumulator is the charge port. Good luck.
