A/C issue ... frustrating dealer response
I took my 2012 Jeep Grand Cherokee (23,100 miles) in to get two A/C issues looked at.
1) When using remote start, the A/C did not kick on.
2) When driving for extended periods, the unit has reduced airflow and is not blowing cold air
They fixed #1 with no problem at all. The invoice says "23069 TSB - 24-002-12 0.20 Flashed HVAC controller with new software for remote start issue".
For problem #2, they said it was likely freezing up and not to run the unit on high. After disagreeing with him, I mentioned the TSB (24-003-12) that specifically addresses the problem I am having with having the A/C on for extended periods and reduced airflow. After I showed him the TSB, he stated the TSB only applied to vehicles with "manual temperature control" and mine has "automatic temperature control". I mentioned I could override and switch to manual mode.
<TSB 24-002-12 is dated 25 Oct 2012 and TSB24-003-12 is dated 30 Oct 2012>
I will admit I was getting a bit frustrated as I am getting ready to go on a long trip and don't want to experience this problem again.
My question that the service adviser was unable to answer. When the tech "flashed HVAC controller with new software for remote issue" did that encompass all updates as of the latest software load or did it only address the remote start issue? In other words, will it also fix problem #2?
Can anyone help? Thank you.
