Unhappy A/C Compressor not shutting down no cycle

I am having a problem with my compressor. I purchased this car a yeay ago and have not used it much When I first got it the air worked for a bit maybe 30 min, the compressor went out, so I replaced it with a rebuilt, I started the car and hit the a/c switch and the clutch engaged, and there is oil in the compressor. So I pulled it down and let it hold down for an hour. I then had it recharged with R12. It blowes cold but the clutch does not cycle off even with the a/c off. That could of been the cause of the first compressor going south. What next? could it be a pressure switch ? Any Ideas ? The only way to shut it down is to unplug it. Thanks Ed

Which car is it? Does the pulley turn freely with the belt off? ( sometimes clutch is too close to hub assy and it will not disengage.)

The clutch is working, the only way it will stop is to unplug it, then the clutch disingage. When I plug it back in, the clutch engage's. 1987 190E 2.3

Sounds to me the climate control relay socket has been jumped or the relay is defective

Could also be a bad evaprorator temp sensor. You probably need to do a function test. Do you have the cd on this car?

I don't have the cd on this model. I will replace the evap temp switch and relay. That may solve it. That could have have been the cause of the first compressor going south.
