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?
