has anyone heard of the problem with one of the turn signals staying on ALL the time? i mean, with the car off, keys out, everything. this happened to me before, and i took it to the dealership. apparantly, the signal relay is part of the BCM, so they were gonna replace that, but it went away before the dealership put in the BCM. they put it in anyway. now it's happening again....but i'm out of warrantly and it's an $800 part. any thoughts?
