A/C blowing hot air

[KLB4]

I have a 2014 Winnebago journey on a freight liner with a 360-hp Cummins ISB XT 6.7L turbo-charged diesel engine. I’m not a mechanic but am handy. I’m tired of getting the run around with the service department and want to handle it myself. Where do I charge the chassis A/C? Seems every year I have to recharge the system. If I have to recharge it every year then I’ll do it myself. Seems silly that the mechanics can’t seem to find the issue without milking me dry. Anything else I should check? If so, where & what?

I had that same problem with my 2008. Finally a Freightiner place found that two fittings were leaking. They did not have the fittings in stock and we were on the road traveling. When I got home I put it into a shop that services ACs, told them what fittings were leaking and they fixed it. AC ran cold from that day on. Just-a-sayin'!


They will have to run dye in the system to find any leaks.
