Your model might be different but without a schematic I can only guess. ---------------------------------------------- Power to the AC clutch flows like this. Battery--fuse--->LowLimit Switch-->HighLimit Switch--->relay----->AC Clutch Positive The relay is similar to this one. http://www.revbeergoggles.com/temp/relay.jpg http://www.revbeergoggles.com/temp/relay-diagram.jpg If the AC relay was pulled and the clutch was still working, then there is a short in the relay center. Try disconnecting the high limit or low limit switches. Just disconnect the wire and that will cut all power to the relay (low limit is on the accumulator, high limit is on the back of the comressor) Ref: http://revbeergoggles.com/Fixes/diag...s.html#sensors If disconnecting the limit switch doesn't stop the clutch then your short is betwen pins 16 and either 18 or 19 If disconnecting the limit switch stops the clutch then the short is between pins 17 and 19 -- DougW |

Re: 97 JEEP CHEROKEE SPORT A/C CLUTCH RUNS CONSTANTLY
I corrected myself. I was saying that the clutch was contantly running and it
is the evaporator that is contantly freezing up. The clutch only comes on when the car is on. I do apologize because that changes everything. With regard to all the other descriptions of my problem with the air flow and such it is correct. DougW wrote: >>> Does the clutch run with the relay out? With the clutch wire >>> disconnected?

Any idea what the 3 relays under the glove compartment do?? DougW wrote: >>> Does the clutch run with the relay out? With the clutch wire >>> disconnected?
