Help...dash a/c

[Jestme13]

We are stuck in Maine with a A/C that won't kick the compressor on. Our ac compressor froze on us wiping out the belt too. We had a new compressor over nighted from Texas. When it was installed with the new belt the clutch will not engage!
We have been looking for the fuse or relay that may be the problem to no avail, even tore the dash apart, no luck. It is an Evans system that they can't or won't help. Does anyone know where the clutch engagement would pick up its power??? I have a schematic from the Evans site that I will show to the tech, I hope he can understand it better then me! Any HELP would be greatly appreciated!!!!!!!!!!!! Another night at the Freightliner dealer

Is the system fully charged? The compressor will not engage if the system is not charged properly. You can run a test of the clutch by applying twelve volts to the lead. If it is good, it will engage. You may have blown a fuse when the old compressor locked up. Not sure where your fuses are on that coach.

The fuse or relay for the compressor would be a Freightliner installation.

It was discovered that the high pressur nipple was cracked during installation of the new compressor. After 2days of chasing circuits the tech discovered there was no pressure in the system. I'm really pissed ! If he had checked the pressure after the refill he would have seen this. A new cylinder head was ordered from Sanden and over nighted, supposed to be here any minute. I'm not looking forward to settling this bill, so much time and parts wasted due to a stupid over sight....... And not to mention the 4 days spent in the parking lot

Glad you got it diagnosed!
