Another Climate Control Question/Problem - UPDATE RESOLVED!!

[EJH]

Guess I'll have to keep an eye on my original climate control issue. It's that time of year here when the temp is cold in the morning and considerably warms up in the afternoon, where I'm seeing my problem. Maybe pull codes again right after it happens?

Unfortunately, you are in the build range for SSM 49264 to apply to your truck
I would have the dealer take a look.

Ok - did a DTS scan for codes and only got a B11DB:08 (battery monitoring module). No other BdyCM or FCIM codes. What the heck?

In regard to the B11D8 code - I had my battery replaced last month and from that time on I noticed that my Auto Start/Stop had quit working. Just looked under the hood and the BMM cable was not plugged in...so that took care of that problem.

After fixing the BMM plug I ran the self-tests on the BdyCM and FCIM modules and they all completed successfully.

Do a FCIM self-test and see if that triggers any codes?
The FCIM in self-test, runs the actuators full cycle.

AirLine Tech - You may have missed it in my last post, the self-test for both BdyCM or FCIM ran successfully without throwing any codes.

EJH - yeah, sure hope it's not the HVAC box warp problem!

Hi - wanted to close out my problem we discussed on this post. It's been resolved! Thank you @airline tech on your suggestion that it may be the driver's footwell temp sensor has failed, and the system is only using the only good sensor (The Vent). I replaced the footwell temp senser and that fixed the problem!!

This forum is great - thank all of you very much!!
