I recently bought a 2019 Ram Classic with a 3.6 VVT engine. On cold starts, the service airbag light comes on, the fasten seat belt light stays on even though the belt is fastened, the a/c fan will not blow, and the backup camera will not come on in reverse. After driving for a few minutes, everything starts working properly. Has anyone else had this problem? Does anyone know what is wrong? Thanks in advance.
