hi david,sounds like a body control module,bcm,all cars have a ecm today.but cars with a lot of electronics .need a bcm to control these things such as climate ac stereo and onboard diagnostics.there is a mode that can store codes so technicians can go in and diag these problems but without the help of a scanner the only other option is change the bcm.good luck please rate my help ty billymac
