I had the exact same thing happen. What I also found was that the high/low
pressure switch was fried. The underlying cause for the chain of failures was
an  increase in resistance due to corroded contacts. My mechanic and  I
corrected this problem by replacing a few corroded ring wire  connectors. You may
also want to check the resistor up front to make sure the  condenser/cooling fan
works on both speeds-its behind the driver's side  headlight bucket. I'm still
working with a slight leak (o-ring replacement  related) on the low side
condenser connection but otherwise have been chilling  down as cool as 34 deg. F.
Good luck.
