What's the harm in letting them check to make sure your system is functional before they go ripping your dash apart?
I know it's a hassle, but maybe let them eliminate the other possibilities on their checklist before they get into doing the TSB.
Actually FCA requires that they have to check & diagnose the issue first, probably in an effort to avoid having to do the TSB for some. Dealer has little to no say over this. And yes, we all know that this first service call will not fix the issue, just something we need to do. In my case, they took the truck back and and two hours later returned it saying the freon was low, so they filled it. They did say try it now and if I still had issues, bring it back and they would do the TSB. I now have an appointment Monday to get the ball rolling, most likely just to order parts for a latter install.
Then it should be listed on the TSB. I have complained 4 times before the TSB and twice since the TSB was issued and all 6 times have been told that my A/C is fine and no repair authorized.
This is the only vehicle I've every owned that if it's over 75F and the sun is out that my back sweats with MAX A/C and maximum fan speed.
No harm. I would rather not have my entire dash ripped out, but I would like to have my A/C blow cold air. 95 degrees and 80% humidity come summer time, with 55 degree air coming out of my vents does not make for a comfortable drive.
The fact of this matter is there is a problem with the original design of the HVAC system, which is still in my truck, as well as every other 2019 Ram and some 2020 Rams that has not had the redesigned components installed. The existence of other issues does not eliminate this fact. That is why the system was redesigned. Then, with a document that says what the diagnosis procedure is, which makes no mention of completing any actual diagnostic procedures, the information I receive is that diagnostic procedures have to be completed, contradictory to the diagnostic procedure specified in the TSB. If diagnostic procedures need to be performed other than what is listed in the TSB, shouldn't these procedures be noted in the TSB?
They can not properly diagnose this issue because the “passing” baseline numbers of the cool down test are originally based off of a faulty HVAC system. This is the EXACT reason that this TSB is a “customer concern” TSB. If the symptoms are described, it gets fixed. That is why the very last paragraph of the TSB instructs the dealer to use fault code CC for the repair. That means they get paid no matter what.
As was previously mentioned, if they perform the cool down test, the numbers, at least for my truck, will likely fall within the satisfactory range. They did last year when I took it in based on the many page thread about the A/C hack. At the time, these numbers are based on a poorly designed HVAC system. Unless they have updated the acceptable performance specifications based on the redesigned system, my truck will likely provide diagnostic results that are in the satisfactory range, but based off a faulty system.
When a customer brings in a vehicle for an issue, is it common practice to review TSB's to see if the issue expressed by the customer has been previously identified? Or, do they just perform diagnostics and if the problem is still not resolved, then review the TSB's? Because the second question is what I am experiencing.
