Ok so I was traveling up to Michigan and my a/c started blowing out like a "fog". things were working till about half way though Ohio.. Yea I know i get that for driving in ohio. The a/c started not working as well. We stopped for lunch and I checked on things and the low pressure line was frozen. After lunch it was unfrozen and things worked great. Been in Michigan for a day or two and I took off and herd a belt squeal so I turned off the a/c. When I got home I popped the hood and when I would engage the a/c the compressor would started to turn and the engine would slow down and the compressor would slowly start to spin. I checked the low pressure ac line pressure and it was at 45psi and the manual says 18-28psi. I do not know where to start. So my questions are..
What do you think is wrong?
Should I take it in?
