I am still very new to the MB picture and I am in need of some help. I had an electrical draw which would kill my battery after 4 days of sitting. I do believe I found my problem was the aftermarket radio install. I put in the original radio and the blower motor comes on without any keys in the ignition and I can not turn it off. Then the drivers side door will not lock with the key fob or the interior remote switch. I am at a loss for where to go next or how to correct this problem. Any help would be greatly appreciated!!!
