a/c compressor cycling losing voltage at idle speed
I have 89 ranger, v6, 2.9L. The a/c clutch cycles off/on about every 2 seconds at idle, as soon as engine is brought up to 1200 rpm or higher the a/c clutch engages and works normal.
I've verified I am losing voltage at the compressor each time it cycles off/on.
I put gauges on system and low and high side pressures are normal.
I replaced wide open throttle relay and throttle position sensor.
I bypassed the low pressure switch and the clutch still cycles.
Any ideas on what I should check next?
