This issue started in late summer/fall of 2017 and wasn’t a problem all through the Chicago winter but now has begun a to be a problem as soon as the temps got above 55 degrees. At night when it is below 60 degrees and closer to 55 the passenger door locks work fine. As soon as it gets above that the doors unlock or unlock part way or not at all and sometimes they lock and sometimes they don’t. One time the tailgate didn’t unlock during warm temps. It was only a one time thing.
I’ve heard through some other controls that there is parasitic control and depending on the temperature different electronics are used depending on the temp so that you conserve energy in cold temps and are more liberal in warm temps.
The battery is new March 2017. I had the original OEM battery from 2004-2017
BCM is Original
Fuses are original
All other electronics work as expected
Instrument control panel works as expected with the exception of light for temperature.
it’s a 2.4 L Manual transmission.
Two videos I’ve found helpful
Thanks in advance!
