mike9723 Posted June 21, 2017 Share Posted June 21, 2017 Hello All, I have the above mentioned Honda with a HUGE problem. Miles are 134,000. It has the fancy dual system with the CLICKING blend doors. Love that feature. The A/C does not work. My local mechanic troubleshooted the problem to an open coil on the compressor AND a bad ECU ground going to the A/C relay. So, he said I need a new compressor and an ECU. SO, that being said and trusting his troubleshooting skills, is it possible to: 1) replace the clutch coil assembly without disturbing the system 2) install a switch to turn on the a/c relay to engage the compressor bypassing the ground from the ECU. And who is the genius at Honda for putting a ground on the ECU anyway. That ECU should be electrically isolated making it impossible for this to happen. How is it I have a Commodore 64 computer system that still powers up and works fine from back in the early 80's and I have this high tech Honda with this issue. I will quit crying now. Comments and suggestions appreciated. Link to comment Share on other sites More sharing options...
HondaPartsConnection Posted June 23, 2017 Share Posted June 23, 2017 REPLACE THE A/C COMPRESSOR RELAY before doing anything else. We have had a LOT of problems with the OMRON relays for the A/C system. Part number 39794-SDA-A03 Its a cheap fix.. Hope this helps Link to comment Share on other sites More sharing options...
