A/C No Green Light and Does Not Work
Hi, I am trying to help my friend fix his a/c. It has no green light and no power going to the clutch. Charge is good. Can't find fuses or relays that control the a/c. I am knowledgeable on a/c systems but don't have a diagram on this set up. Any help will be appreciated.

AC and heater fuses are behind the glove box right below the heater relay:

Thanks, I will check today.

Might be a bad low pressure switch.

You can easily rule out the pressure switch by shorting the following terminals if needed:

parden my ignorance but is the purpose of the pressure switch to keep the clutch from engaging if there is no pressure in the system?
