My 1999 Astro Van AC does not turn on. Good fuse,relay but gets no power to the switch into compressor.Can it be the heater/air condition control panel.


My first thought is, your low on refrigerant.
Checking fuses is good, also, use a test light and check voltage on fuse circuit. Some fuses are hot all the time. Some go hot with key on. I see three fuses involved and a/c enable relay.
Sometimes you can take electrical connector loose from compressor and use jumper wires from the battery for voltage and ground, just to see if compressor clutch will engage. The dark green wire is voltage, the black wire is ground.

No current to ac compressor


A mechanic would start at the compressor and work back.
Did you jumper the low pressure switch, or the relay, or put power directly to the ac clutch ?
You have a low pressure switch that should be closed and a high pressure switch that should be closed to put power to the compressor clutch. If the freon pressure drops below 20psi the low switch opens, if it goes above 300 psi the high switch opens.

What's your problem?ac compressor clutch has no power 95 blazer,all fuses are good,all relays are good,where do I look next?


make sure there is free-on in the system.{there has to be an ample amount of free-on in the system to turn on the compressor.}1. disconnect the high pressure switch. take a jumper wire and jump the pins. compressor should come on. if compressor comes on the switch is bad.

Ac compressor wont kick on when running air Full of refrigerate to! jumper wire to compressor and ran! What is it Ac relay or wiring?


It could be the fuse, climate control, switch, or relay.
If you check at the switch, that will also tell you if the fuse might be bad.
Then if you check at the relay, that will tell you if the climate control is bad.

AC PREASURE IS GOOD BUT COMP WANT COME ON CHANGED PREASURE SWITCH NO HOT POWER TO SWITCH


Check the a/c compressor relay.Remove the relay and use a jumper wire between terminals 30 and 87,if compressor comes on then the relay is bad or the high pressure switch is bad.

If you have no power (12v) to the power wire at the A/C compressor clutch and have jumpered all of the switches then you need to check for power coming out of the A/C switch on the dash. Also there might be a pressure switch on the back of the compressor that you can jumper also. You can also check A/C compressor relay in the under hood fuse/relay box. There might be a fuse in the under hood fuse/relay box for the A/C too. Hope this helps.
