Air Conditioning Problem – Honda Prelude
Question:
1990 Honda Prelude Air Conditioning Problem- The a/c will work idling for quite a while then when it does quit working the compressor clutch will not engage and the red warning light comes on. I’ve tested and it is not energizing the compressor relays. The fans work, it is full of freon, the compressor clutch is not slipping, and I replaced the belts. I wanted to replace the compressor control unit but the part has been discontinued and i need to figure out if that is what it is so i can look in a salvage yard to find the part. Any suggestions on what the problem could be other than the compressor control unit? Could it be the sensor in the compressor, and if so do i have to evacuate the system to replace it? Is there any way to get diagnostic literature on the system?
Answer:
Look at the a/c cycling switch as a cause of failure. A/C Diagnostics
