Subject: DML: air conditioner clutch intermittent
1999 SLT 3.9L, Sanden 4692 A/C compressor.
Clutch picks up normally when cold but when turned or cycled off at
operating temerature the clutch will not re-engage even though there is 12
vdc at the clutch field coil wires.Clutch field coil reads 3.7 ohms all of
the time, working or not. No excessive noise or heat noticed during
operation, only the normal "clack" when the clutch does engage. A/C works
great when the clutch engages. Any ideas?
