A few things unexpected with replacing the BCM.... That are now fixed.

On startup, about a minute later, I would get the message about ice possible. Then it would go away on its own in about 10 seconds. Pretty much ignored it and shocked it up to the Dorman HVAC module. (New ambient air sensors had no effect) I just realized that message has disappeared.... Didn't even notice it until yesterday I was driving along and the temperature was dropping, the message popped up at the same time the rear view mirror showed 32°.

I always assume the previous owner had unplugged the seatbelt sensor, to turn off the annoying chime. I kind of liked that.... Live in a small town and nobody wears seat belts and it's not enforced. Well now I get the flashing light on the cluster and the chime dinging.... So I guess that's fixed as well.

Guess the old BCM had a few more problems besides the rear hatch ajar circuit....

 

I received the ICE POSSIBLE WARNING on my cellphone + tv news which I verified as my driveway & street was covered in ice this morning.
I didn't have to drive with my FREE delivery to get my delivered this morning.
