1999 Suburban, 33K miles. The AC clutch doesn't engage. Checked fuses 1 interior OK, One in engine compartment OK. Swapped identical relay in engine compartment, no change. No current at AC clutch plug.
No clutch engage when jumping from battery to prongs on clutch assembly. Added about 1/2 can of gas, while engine was running but compessor was not. It appears that there are two problems. The clutch not engaging, are the prongs + and - or is it internally grounded? Why no current at the engine side of the plug?
