Gone for a week on vacation. Come back and get in the car that stayed behind and didn't get driven for a week. No prior notice to the AC getting worse before we left. Now, AC not working. It abruptly stopped working. Fuse good, compressor coming on, only ambient air from the vents.
Hooked up manifold gauges and got this reading with engine idling and AC running for 15 minutes:
115 PSI Low pressure side
150 PSI High pressure side
(The low pressure side started out at 85 PSI when first started engine)
After running for 15 minutes and turning car off I get these pressures:
125 PSI low pressure side
135 PSI high pressure side
What is your expert diagnosis? What would you begin with?
