2006 Kia Sorrento; had a/c compressor changed in May, 4 months ago and a/c won't work sometimes and sometimes works
My a/c in 2006 Kia broke down a few months ago. I had my a/c compressor, etc. changed at a shop. Now sometimes the a/c won't come on and sometimes it will. Recently after trying everything I could think of I slammed my hood down because I was so frustrated and it came on. What could this be?
