Compressor is not getting power. April 28, 2013, 06:14:16 PM My A/C stopped blowing cold air. The compressor is not kicking on like it should. The first thing I noticed was the fan switch was fried (burnt, melted), so I put new individual connectors for better contact. I also replace the fan switch with a better one and it still won't turn on. I was wondering if this part could be the problem, It changes from A/C high to low to vent, ect. but no compressor. Thanks!

Compressor is not getting power. Reply #1 – April 28, 2013, 07:01:03 PM My a/c quit hen it ran out of refrigerant. The switch turns it all off when it gets too low. Fixing that this week with a new liquid line. Quote Selected

That would be ok with me if that is all it is. Thanks! Quote Selected
Compressor is not getting power. Reply #3 – April 28, 2013, 07:44:25 PM Check the charge. Vinny is correct if low it wont pull in the clutch!!! Quote Selected
Compressor is not getting power. Reply #4 – April 28, 2013, 08:05:51 PM Strange I have never had any problem with it before, but a lot can happen when you are replacing an engine, transmission, ect.. If I need a new compressor, now would be the time for it. Just about every thing else has been replaced. I appreciate the help guys! Quote Selected
Compressor is not getting power. Reply #5 – April 30, 2013, 11:40:25 AM I just had my charge checked and I was only a couple of pounds low, so now it's full. They said no sign of leaks and that the compressor is not kicking on because there is no ground to it. So, where is the ground wire located for my compressor so I can connect it to the chassis? Thanks! Quote Selected
Compressor is not getting power. Reply #6 – April 30, 2013, 01:02:01 PM If you recently replaced the engine (I think I read that) then I would check you grounding strap to the block. IIRC, there's no dedicated ground to the A/C compressor, there's like 2 wires that plug into it.I thought about the ground strap cause I remembered a pick-up I had that had the bucking/stumbling on acceleration, but smooth at idle. All it was was the ground strap wasn't put back on. Just a thought. Quote Selected

Compressor is not getting power. Reply #8 – April 30, 2013, 10:35:56 PM I checked for my ground cables and both are grounded. I have one going from the back of the head to the firewall, and another going from the front of the block to the engine mount bolt. Quote Selected

Compressor is not getting power. Reply #10 – April 30, 2013, 10:52:40 PM With the engine running and the A/C on, check the cycling switch for power. It's the one by the firewall on/near the acspoogeulator. If you don't have power at the Light Green/Purple wire, use a jumper wire to send power down the Pink/Light Blue wire. See if the clutch engages when you do. This tells us whether the clutch is being commanded at the first point, and it tells us also if the rest of the clutch circuit is viable. Quote Selected

Compressor is not getting power. Reply #12 – May 01, 2013, 08:16:11 PM If the engine was not grounded properly it would not crank correctly. The ground for the clutch is one wire on the connector near the compressor. Normally the clutch has 2 wires one is a GROUND!!! Quote Selected
Compressor is not getting power. Reply #13 – May 01, 2013, 09:40:10 PM Engine cranks fine, starts right up. Compressor has a connector on top with two wires. Obviously the ground wire is not grounded. The ground wire appears to go into the cluster under the dash. Tomorrow, I start with TFYK's suggestion and see what I will find. Then I will try to trace the ground wire under the dash if need be. All I know is I lost a ground and I need to find it and ground it. Would there be anything wrong with pulling the ground wire from the compressor out of the harness and grounding it to the firewall or chassis? Thanks! Quote Selected
Compressor is not getting power. Reply #14 – May 01, 2013, 11:41:42 PM I guess I missed the whole ground thing. Still, the first connector from the clutch is easy to miss in an engine swap. It's in the area of the yellow circle. Follow the AC sub harness from the compressor, it should go through a pair of 2 wire connectors between the engine by the power steering and the body by the coil. Quote Selected
