90 lumina a/c problem

[caw333]

A/C quit yesterday. Changed eveything out a couple days before and couldn't get the thing to work and then just out of the blue it started working. Its seems like a power problem. If using a test light and the key turned forward shouldn't the light be coming on when grounded good and touching one of the pigtail things. Also all I can find is a relay that is good. but no fuse. Found one fuse but it cuts off the blowers, its in the glove compartment. The system still shows to have a good charge.

ok. . . lets try this, If a low pressure sensor is bad I can just jump across it with a paperclip to get it to make, but if its the high pressure switch that is bad what could I do to see if its the switch. Can you just unplug the switch to see if will unmakes or am I just out of luck. I'm not getting power to the power harness. If any one has any ideas on this,Thanks

Check the compressor relay contacts in the underhood center, also there is a seperate ac fuse.
