Trying to button up a few of the last items on my 1995 SC, that weren't finished before the Hot Rod Power Tour. AC components were added back to this car after running with the systems fully removed for 3 years. Wife won't ride with me till they work, so trying to get systems on board.
AC System new components are:
New OE Condensor
New Lines - Both
New Accumulator Dryer
Used but considered good parts:
A/C Compressor - clutch engages if powered directly from Battery w/ pigtail
Low pressure switch also called A/C Cycle switch in the service manuals - no change in systems if paper clip is used to bypass.
High Pressure Switch on return line - no idea.
On the power tour we tried to add freon without luck. At that time we discovered 0 voltage at the compressor also the condensor fan does not kick on with A/C. We were told IRCM as the culprit...I keep a spare in the glove box so that was changed out.
I now have 8.8v at the compressor but it does not engage. If I manually engage the compressor with a pigtail to the battery it pulls the clutch in and runs.
At this point my questions is first could someone who has AC tell me what voltage they have at the compressor? Should it really take 12 full volts to engage the clutch? Could I still have a bad IRCM? ...I have another spare I could try (figured I'd ask first).
Stumped as to were to look next.
