I have a 2004 Berlina and whenever i lock the car using the remote my left side blinker stays on. to fix this i lock and unlock the car several times before it turns off.
i'm just wondering if this is a problem with the key itself or the car's computer?
Its caused by a problem with a relay inside the BCM (Body Control Module)which is the computer that controls various body and security devices and systems. ..Theres a "how to" on here somewhere that shows you how to replace this relay if you are any good at soldering electronics.
