Need help with AC issues

countryboyco99 · May 16, 2017

I have a 2010 Ram with the 4.7 and my AC keeps cutting in and out. Not just as I start off or hard acceleration. Replaced fan clutch recently and can hear electric fan running. Any ideas please help it's getting hot in Florida!

Possibly low on refrigerant, you would need a set of gauges to diagnose.

It works great going down the road but the issue is when stopped idling in traffic

Low side 20-30 between idle and 2000 rpm. High side was 250-325 from idle to 2000 rpm.

I'm a DIYer for most everything but AC is one of those things I leave to the pros. If you have a shop you trust I'd let them diagnose. Hopefully something simple...

Is the interior fan on high while those pressures where taken? Try cleaning the condenser coil, if the electric cooling fan is two speed, make sure low speed works.

Yes interior fan on high and system in max AC. Not sure if electric fan is 2 speed it's the stock fan from the factory.
