That went on for a couple months. Now the ac completely stopped blowing cold (blows hot air). Today I hooked up a set of gauges. Before ever starting the vehicle the gauges read:
High side 120
Low side rapidly increased to over 150 as soon as I hooked it up so I disconnected it.
I'm ac ignorant and can't afford to pay for ac work. So what are some thing to look at to diagnose what is going on?
Did the clutch stop working?
