Sup guys and girls, I have a problem with my a/c compressor. It does not get no power at all it would only work if i was to directly connect it to my battery, but on the car harness it does not work. I used a circuit tester to test the connection and it's has no power through the line. What could be the problem? Relay?

O yea i drive a 1993 Honda Prelude Si with a JDM H22A Swap

What could be the problem? LOL

Some things to check in no particular order: Proper amount of freon, fuses, relay, presure switch, t-stat, grounds, wiring, connectors.

 

First thing, is the green light on the AC switch coming on? If it is you might want to check the condition of the low pressure switch and harness which you can access from the front of the bumper on the passenger side. Pull off the plug and make sure the wires and plug are not rusted. If all looks good try jumping the two pins in the plug with a wire and see if the compressor comes on. If it does check for continuity on the switch itself with a meter. If you don't have continuity you may be low on freon or the switch could be bad.

Good luck.

 

cool cool i will have to check on those things tonight. Thanks alot guys. I will let yall know if that solve my problem

 

also check for loose connections too

 

man.... i check the connections to the compressor and the wire to the compressor is dead meaning the wire has no power!!! whats could be the problem???!!!

Did you ever find a solution to your A/C compressor problem for the 1993 Honda Prelude Si? I’m having the exact same problem with my 92 accord. Any information you can provide will be greatly appreciated.

Thanks,

well as for the prelude, the climate control is known for loosing connections inside. When you push your a/c button on the climate control, is the little green light coming on?

 

put some gauges on teh system

without knowing what pressure is you can fight with it all day long. if the pressure is too low/high the high pressure switch will cut power to the compressor.

 

Yes, the green light does come on.

 

When the compressor is connected directly to the battery it comes on.

Is there some relay or wire from the A/C button on the dash to the compressor that could have possibly failed or burned out?

 

Maybe a fuse?
