1985 Air Conditioning/Electrical Issue

[marietta911]

Hello. New to the forum. Been meaning to join for awhile. Issue with my air conditioning gave me the push to do it.

I have a 1985. I have an intermittent failure of ALL power to the A/C system. Fuses are good. I can remove relay covers and activate either the condensor and or a/c blower manually and they will work. It is like the main power feed to the a/c system has a bad connection. I have the service manual and have been going through the wiring diagram on page 970-47 (bentley productions book). I am pretty handy regarding electrical issues and have a high quality meter. I know this is one of those issues that is difficult and is a hands on problem. Any help including locations would be appreciated. I am questioning my ground but haven't been able to nail it down.

Any insight would be very appreciated

If your gas is low (very common) the clutch will not engage on the compressor, welcome to the woes of 993 a/c. Kwick-fit do re-gasses very reasonably and will check for leaks. No gas no blow also check out this useful site:- http://www.bergvillfx.com/porschehvac2.html
