[DML] A/C cutting out

["Ryan Wright" <ryanpwright@xxxxxxxxx>]

My A/C simply cuts out sometimes when driving. The air will blow nice
and cold, then at random will slowly get warm. It eventually kicks
back in and cools down again, sometimes after 30 seconds, sometimes
after 5 minutes. Driving doesn't affect it - I can be at idle or at
speed the entire time.

I suspect one of the pressure switches is kicking the compressor off
when it shouldn't; all fans (interior blower & cooling fans) are
working fine. I'm running R12 and the system is full per DMC specs.
A/C shop looked at it but the problem is intermittant and they're
having trouble diagnosing it, as every time I bring it in the darn
thing works fine.

Any advice on how I might troubleshoot this?
