Default Re: A/C sometimes blows hot air & sometimes cold..don't think its the compressor...

I re-read the post and agree this may be another scroll control valve issue. If highway driving or above a certain speed results in cold ac but low speed stop and go results in warm air then the scv may be faulty.

To understand scv issues, troubleshooting, symptoms and repairs, this link may help; http://www.saturnfans.com/forums/sho...+control+valve
