BigAl Posted July 14, 2018 Share Posted July 14, 2018 My A/C light flash then no cold air. The belt is tight and the a/c is full of freon. It only flash after driving 30 minutes. Any ideals? Thanks! Quote Link to comment Share on other sites More sharing options...
Filehorse Posted July 14, 2018 Share Posted July 14, 2018 How do you know it's fully charged? Unless you've put a set of manifold gauges on the system you have no way of knowing what the real story is. Sounds like a pressure sensing switch is causing the unit to trip out but you gotta put some gauges on it to know for sure. Quote Link to comment Share on other sites More sharing options...

When the engine is cold, no problem. It only flashes after driving 30 minutes of driving. Quote Link to comment Share on other sites More sharing options...
Filehorse Posted July 14, 2018 Share Posted July 14, 2018 You may want to think about taking it back to him if you're comfortable with his ability to troubleshoot the system. This is going to require a level of expertise above shade tree. Good luck and let us know what the problem was. Quote Link to comment Share on other sites More sharing options...
