Have had the car serviced with freon, fixed a leak and now the compressor has no power nor do the cooling fans. How do I trace this out? I found no fuse blown but suspect that one may be hidden somehow. Please help!

Re check all fuses with a test light.

Did the system work prior to the repair?

There are a series of switches that protect the system from working with no freon. What are the pressures at rest?

It appears all fuses are good.
The a/c was never used before since all use was winter time. I got the car used and did not know the seller.
The mechanic friend that serviced the a/c put in four cans and we were about 2 ozs short of full.

Appears? Once again, needs to be checked with a test light.

Was the ac on when he installed the freon?

The fuses weere tested with a test light with ignigtion on.
The system was working inside the car but apparently the compressor never did come on.

Also the fuses have no detail list on which belongs to what system nor does the one in the trunk. But all were checked with everything turned on and I will go do that again while waiting for the response.
Thanks
