hey there everyone, My AC will run for 10 min or so then turn off, and then come on again after a few minutes of being turned off. I Had the system charged so I know that is good. I try and jump the switch at the firewall and when the unit has turned it's self off the clutch will not trip. Making me think it is the coil that may be getting hot and not working till it cools down. Any thoughts?

Also working on a P0420 problem, I replaced the up stream but the light is back on so it must be the cat. The cat has been replaced but the truck has 148K so who knows when it was done.

Thanks
James H
