A/C Woes- Can Anyone Shed Light?

[Robert Myers]

Kerry,

I had an '89 200 with intermittent AC.  It turned out that the relay which 
controlled the AC compressor clutch was intermittent due to a fault in the 
wiring underneath the relay socket.  Somehow the connector wires in the 
fuse/relay box under the hood had been pushed in deeper than their proper 
depth and the relay pins were only making partial contact with the 
connector wires.  Sometimes it would work and sometimes it wouldn't.  It 
seemed somehow to be related to the phase of the moon and the time of day 
and whether or not the driver had had his morning coffee or not.  :-)  The 
trick is to get underneath the fuse/relay box (just _barely_ reachable from 
the driver's footwell area) and push the connector wires back up where they 
belong.  Then hope you never ever have to pull the relay again.
