With the help of a guy at autozone and the repair manual, we tracked it down. It was a in-line sensor on the heater hose(from the front of the engine look to the left of the plenum). In my case it had been bypassed all together which caused all kinds of problems since hot water was running through the system all the time. So, $12 later I put a new one on and it seemed to fix the problem. I also replaced the pressure sensor on the a/c accumulator too which was about $12 because it would get stuck in the 'off' position which of course cut off the compressor. Don't know if any of those suggestions will help but it's a cheap place to start.
