it's weird. when i got the car, a/c worked great. Then, after driving 1200 non-stop miles, a/c died.
the next day, a/c didn't work. but the next day, a/c worked great.
I thought it was the compressor, so i replaced the compressor. I didn't chance drier, expansion valve, and I did not vacuum the system out before charging. Instead, i installed a new compressor and charged it with freon. (so it is possible that i have air in the a/c system)
anyways.. it worked great for a few days until i had to put another 400 miles on the car.
A/c works only when i drive around short distances.. but for after driving more than 300 miles, a/c doesn't work for two days.
Any suggestions?
