Question about 1997 Chevrolet K1500
I am not sure whether they are switching the ground or B+ on that vehical on the pressure switch. Do any of the legs in it read to ground? The A/C compressor quit running. The clutch does not seem to pull in. The 10 A fuse is good and the relay does not activate. I swapped the relay with the starter relay and the engine started so I think the relay is good. I recently added a can of freon and noticed that there was a leak at the check valve on the suction port. Maybe it lost all the freon. I shorted the wires going to a pressure sensor and still it would not run the compressor. Is the any thing else in the circuit that will prevent the clutch from pulling in under loss of freon? What is the normal way to recharge a system when it is so low that the compressor is cut off by the low pressure switch? Thaks Roger
With the engine NOT running, pull the connection to the compressor clutch and hit the terminals with 12 volts from the battery. If the clutch clicks it's OK and probably is not working because of a low freon interlock if there is one.
You said you added a can of freon...... was the clutch working when you did this? If it all went sour when you added the can , could you have done it wrong and dumped the rest of the freon?
