AC Fix TSB (Pre 8/20 build trucks)

[Brewbud]

Is anyone elses just not blowing hard enough? Mine was cold in AZ summer, just felt that the blower on full was like other cars on medium at best. Here, I see people have temperature of outlet air problems. New HVAC box sounds like it might have something to do with the fan and hence volume.

Standard HVAC controls here.

I'm not going through all that tearing down just for more air volume that's for sure.

Do you have the "Auto" AC function? Sometimes that will blow a crazy volume of air. There is no manual control that will match it though. Odd. But I know the system can do it.

Mine is the standard poverty knob, no auto.

I wish they put this much effort into fixing the CP4 debacle if their willing to tear apart a dash and do a 7 hour job on 100,000+ vehicles just because the A/C takes longer than normal to cool.

It isn't that it takes longer to cool.. it simply doesn't cool because it doesn't blow cold enough.

Exactly, and it's annoying to have to drive around with the blower on high in a $75k truck because the air coming out of the vent is not cold on 75* days.

I've been waiting on something like this for a year and a half, but after seeing what's required, I have my reservations. I've learned to live with the poor performing AC. Like most, I don't want them tearing into my truck. So far, I don't have rattles, etc. I have a feeling I might have a few after this repair.

I got my windshield and front windows ceramic tinted to help repel heat to assist the ac. I already have a squeaky dash so maybe I have nothing to lose

Hmm im gonna call the dealer today and see, free improvement is good gotta try to get as much as i can from fiat they made sure to get as much as they could from me when i bought the truck lol

I had this TSB done to my truck last week. Mine has the dual zone temp control and when on auto the left vent would be much warmer than the right. The AC has always blown plenty cold, but sometimes took 5 minutes to cool down. Only problem I am having now is there are some scratches in the clear plastic over the gauge cluster so Im trying to get that taken care of. Not sure how they could be so careless as to do that, but alas its a Dodge service dept, I shouldnt expect anything better. I was worried about a squeaky dash but there seems to be none of that.

I just spoke to the parts guy at my dealership, I'm going to have them do the TSB on the 2019 5500 we bought for the shop, and i'll see if it makes enough difference to bother having it done on my personal 2500.

Please let us know how it turns out.

First post of someone having it done results in interior damage.

Yep. I'm good. I'll deal with what I got.

If something is damaged hold them accountable and get it replaced.

Pretty much.... take pictures before in case they balk at fixing the damage.

I just saw this thread. I am going to o call my local dealer and schedule this TSB. My A/C sucks in the summer! Fan seems to run high to blow more air. Ill photo and video the hell out of the interior so I can document any scratches. As soon as I know when they will get it in I will post more.

Yeah I should be able to turn on the truck in the middle of a hot summer day, turn the AC to full blast, and become a meat Popsicle.

Last summer I’d have to drive with the windows down and keep the fan low for a while before it would be cool enough to turn up the fan. And even then it was never freezing me out.

i hate the idea of techs ripping the dash off for this job, but it’s a necessary fix in my opinion

I waited till now to go get the TSB done, didn't want be the first. I called the dealer and they said they needed to run diagnostics on it before they can do the TSB. He said temp difference between vents and also part numbers are part of the equation to get approval to get the TSB done. Approval??? Guess we will see. My AC is horrible. I picked my truck up June of 2019 so I thought it would be a done deal. Guess we will see...

Have we confirmed that the fix actually makes it much better? If so, i must have missed it

The few that had it done and posted about it said they had 10 degree cooler air than when the truck went in. Something like 53 degree air to 42 degree air afterwards.

My truck was done a couple of weeks ago. Huge difference. More air volume for heat and A/C and the air is much colder .
