Thread: Another compressor ? ....sorry

what did you get done in the valve bock rebuild? was a new diaphram fitted? I would check this if it hasnt been done already.

You seem to have done all the right things...
Here's a couple of additional points ...:

1. You might, just might, have a dodgy sensor: the ECU may be continually trying to get the "expected" response / reading...so keeps the compressor running in order to achieve it... have you had any "over pressure" faults or similar message

Put the truck to max height, open the top tail gate to stop EAS activity and put jack stands under the chassis. You then can safely crawl underneath and swap the front and rear sensors from side to side so that they "articulate" through a different sector of the variable resistor, thereby bypassing the corrupt part, if that's the issue. You may not even have to recalibrate the system...

2. Located under the coolant expansion tank is a large circular connector: It's the major link from the fuse box. It is well worth unscrewing the outer slip ring and prising it apart, carefully cleaning the prongs and receivers ... esp. for leakage paths caused by corrosion etc. Especially also check the ground points.

3. There's also an EAS connector behind the ? passenger footwell which can become corroded from leaking around the pollen filters. worth checking for continuity.

If I can think of any more I'll let you know!

good luck

G`day ,

You could try the bung on the tank with soapy stuff , often forgotten about .
