AC Problem 850 1995

Soory about the blank post - seem unable to log in.

Anyway......

There are some common things to check. As you mention there is a high temperature cutout on the compressor which in many hot countries is often disabled to prevent false operation.

Secondly, in high temperatures it is possible for the internal pressure to rise too high - this will cause the high pressure switch to oprate and close the system down until it recovers. An overcharge of refrigerant can cause freezing of the evaporator, causing blockage in the system. The low pressure switch will operate to cut off the compressor until the system recovers. Was your car topped up with R134 recently?

Good luck
