I have a long standing problem that is now an emergency as I am planning an 8hr trip with the dogs in a few days.
Anyway, in my 2003 2500 5.9 CR, I lose air flow from the vents, but only after the A/C has been on for a couple hours or more. After that, it kind of gets weaker and stronger (mostly weaker) with no pattern except I can park for a couple minutes and then it’s good for a little while at least.
I take 4 hour trips on the ram pretty much weekly and the problem has been very consistent for over a year. I have a newer ignition switch and blower and don’t know if this issue happened before or after I changed those. I have no recirc door and have bolted both mode doors in place. From what I can see, my coil is very clean. The water drain seems to be working as it is making puddles quickly enough. My blend door still operates as it should, as far as I can tell.
I am thinking my blower is maybe getting tired but it sounds good. I read that the older 2 gens have vacuum controls and I’ve had plenty of issues with that cruise hose over the years, but I don’t think that affects the 3rd gen a/c. Anyone have any tips? I’m completely lost here.
