HELP! 2000 E350 SD Van AC stumper...

[divemaster]

Hi there,

I have a 2000 E350 Super Duty van and the AC compressor will not come on. I have power on both sides of the pressure switch but still the clutch will not engage. Any suggestions??

Thanks in advance,

Shane

If you are getting power to both sides of the low pressure switch that narrows it down quite a bit. There is only the A/C relay and the clutch on the compressor after that .
Bypass the relay and see if the clutch comes on. Or you could run a hot wire from the bat to the terminal on the compressor to see if it works.

Thanks for the advice, I will try that. Any idea where the relay is located? It is not in the owners manual...

there is no power to the ac clutch with the engine running and the ac on high.... I can't seem to find a relay or a schematic.....
