This is in a 2000 Integra Type R.

I have checked for voltage to the AC compressor power plug AND the pressure switch. Neither have voltage, so it's not because of low pressure.

We jumped the compressor plug directly to the 12V power source and the compressor kicked on fine.

Next we pulled the AC diode from under the dash to check continuity, that is working properly. I pulled the climate control and checked the AC switch for continuity, the switch is ok. We checked for voltage on the wireharness plugs going to the switch, they have voltage.

We swapped around the relays under the hood in the main fuse/relay box, that didn't kick the compressor on.

What the hell else could be causing the compressor and pressure switch to not be getting power?

 

Totsie, whats up man? Did you ever resolve this issue? Im having the same problem.

 

Do you not have a wiring diagram???? check your condenser fan fuse (20A number 56 in engine compartment) should have power to it all the time. Fuse 17 is for the excite side of the compressor clutch relay, and fuse 56 is the switching side to turn the condenser fan and a/c compressor clutch on.

 

HELP!! MEE TOOO!!!
I NEED A WIRING DIAGRAM.
someone cut my ecu wiring for the A/C compressor, clutch & fan
HELP

 

I sent you a private e-mail telling you how to obtain the 3 PDF pages you need to properly troubleshoot your electrical problem. This should be exactly what you need. These would be pages 22-5, 22-14 and 22-15 of the 98-01 Integra FSM.
