Just picked up an 03 A4 with the rear doors not having any type of power. Windows do not work and the doors do not lock with key fob or by manually locking them with the key in driver door. Also the dome lights always stay on with all doors closed, so to avoid battery drain I have to manually shut them off via the interior light switch. Also security system is acting weird and sometimes my key fob doesn't work. Was thinking it could be the comfort control module as it controls all that stuff but the weird thing is everything else on the car works fine. Sun roof works, when the key fob is responsive (8/10 times) the front doors lock and lights flash but there's no "beep". Fuses are fine, so is the drivers door wire harness. Anyways all my research points to the ccm but I'm just a little skeptical since all the posts I've seen about the ccm say that none of the "comforts" work and not just partial like my situation. Any insight would be greatly appreciated! Thanks in advance!
