I have a 2005 impreza with the 2.5i with 56000 miles that I bought a week ago.
When I get in my car my heater blower works great. After I drive for a while the heater totally stops blowing air into the cabin.
I figured out (i think) the evaporator was icing up as I drive and when I shut the car off it melts.
I charged the AC system to the specifed pressure and the AC stopped working all together - the compressor would kick on, and the belt would squeal like crazy and the RPMs drop drastically. The compressor kicks off and the rpms come up. No cold air out the vents
I let some pressure out and the AC started workign again, but it ices up and stops blowing any air. Its not a problem on short trips, but on a 2 hour drive there is no climate control for 1.5 hours
Can you guys help? what do I need to do? Is this a common problem?
