2003 Uplander, front passenger seat belt will not extend. Have to "play" with the belt manually retracting webbing and extending until it releases. Have been told there is a sensor that requires body weight on the seat in order for belt to extend. Any experience with this problem and a possible solution?

 

the weight sensor is for the passenger presence system determining passenger airbag deployment; not the seatbelt.

either the d ring loop that bolts to the b pillar is clogged with gunk or the seat belt retractor is no good.

 

If it's a 2003 it's not an Uplander
