I have a leak in my A/c system. I checked it over with a sniffer and it's leaking from the two hoses from the compressor and the dryer switch which I think it's called high pressure switch? Anyway, I need to know if the lines from the compressor is just an o ring not an gasket.

Also when it leaks from the base of the switch, it normally means bad o ring not the switch itself correct? I don't think the a/c system ever been touched until now.

 

Never messed with jeeps ac, but everyonether one I seen were just o rings. Make sure u sniff good under the dash from inside to check evap..

 

I'd check the o-rings first. I sell Sanden compressors and make ac hoses for a living and o-rings are my first guess if it's leaking at the spot the hoses attach to the fittings.

 

That what I thought. I sniffed everywhere and it just those two spots. The switch base and the compressor hoses.
