What controls the compressor? I just replaced a bad compressor and still not working. I can make the compressor come on by forcing with a jumper from 30 to 87 at the relay

A/C compressor spins, but why is there no cold air?


You may need a shop manual to get the wiring diagrams and test procedures.
The ac compressor gets power from several sources and those would need to be checked. The control on the dash, the low and high pressure switches, the relay, and so on.
If the compressor is ok, you should be able to jumper the clutch like you did and feel one line cold and the other line warm if freon is flowing thru the system.

1) TEST the fuse+ relar of a/c
see the next steps and fix it. God bless you
If so, the compressor is working and the A/C system probably contains enough refrigerant to make cold air, so the problem is inside the HVAC unit. Replace the motor that controls the blend air door (this is a difficult job and best left to a professional since it involves tearing apart the HVAC unit -- about an 8 to 10 hour job!).
If the compressor does not engage when you turn on the A/C, see if it will run by jumping the compressor clutch wire directly to the battery (use a fused jumper wire). If the compressor works when you jump it, and the A/C blows cold air, the system contains refrigerant and the fault is likely a bad A/C compressor clutch relay or a bad clutch cycling switch or pressure switch.
If the compressor does not engage when you jump it, the problem is a bad compressor clutch.
If the clutch engages but the compressor does not turn (the belt will start to slip and squeal), the compressor is locked up and you need a new compressor.
If the compressor clutch engages and turns the compressor, but the A/C still does not blow cold air, the system is probably low on refrigerant and needs to be recharged

When I remove the a/c relay and jumper the connection my a/c compressor clutch kicks in. When I removed this jumper the compressor will not engage. Is there a sensor or a switch located that controls this....


May have a bad low pressure/cycling switch. Its a two wire switch and normally found on the dryer/accumulator. You can unplug that wire and jumper it. If the clutch kicks on then either the system is too low on refrigerant to activate the switch or the switch is bad.
That switch can be replaced without loss of refrigerant because there is (or supposed to be) a shrader valve in the dryer.

take a look at www.strutmasters.com. they sell kits to replace that whole mickeymouse system.
they never really work after the warranty expires. now that you have dumped that much money into it and it still does not work, you should think about a real coil spring and shock system.

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.

Can't see filling with freon without compressor turning. Put jumper wire on high/low pressure switch harness to see if clutch engages. If so, bad high/low switch. If not,check power to high/low harness via fuse,relay, or dash control.Battery voltage applied to compressor if accessible will also engage compressor clutch and read your low side with your fill gauge. 30-35lbs is good
