Why is the a / C CLUTCH not engaging on my truck?
I jumped both switches and pressed the “AC On” button – clutch did not engage. I used that cheapie pressure guage – it connects to the fitting on the low side tube. It read about 9psi. The “low range” on the dial goes to 25psi, then the “full range” goes 25psi to 45psi. Then there is an “alert” and a “danger” range above that.
