Hey guys.. My passenger side seat belt won't retract anymore. Same thing happened to my driver side seat belt like 4 years ago. I had it fixed at the dealer a few years ago and it was expensive. I just called the dealer about this one now and they want $600 for the part and $300 to install. I think it is just the motor that is not working. Anyone else had this problem and it was just the motor. I found this motor on ebay and I think it should work. Any info would help. Thanks guys.
