Hey guys i got a problem. Soooo... I took my 2008 Impreza to garage they changed my oil but said my A/C was busted. I didn't trust them but soon after I left I noticed my A/C would run cold then turn hot in less than 5 mins. So i went to another garage to get the A/C recharged (over a year later). They told me when they pumped my system I only had 13 grams of freon when i should have had 1lb in the system (my best guess is the first place pulled it out of my system as that during their "free inspection" i saw them messing with my low pressure line). After they filled the system they found no leaks so I know my freon is staying in my car.
All that aside now my A/C blows cold then slowly gets hot. From what I have seen online it is suggested to replace the A/C Clutch but I wanted to know what do you guys think? My worst fear is that my A/C Compressor burned out because of the lack of freon but I don't know enough about the A/C system to say for sure that is what went wrong.
