POWER SEAT 56000 3.8L

1998 Buick Park Avenue

The power seat motor on the drivers side runs when I push the up/down button but the seat won't move. I looked at motor and the shaft (wormgear) is not turning. All other motors Driver and passenger function properly. Is some checks I can do to before yanking it out? It does not look too hard but I am sure there are some tricks to make it easier that I do not know. Thanks for your help.

If it was me I'll disable the other barrel it only comes in play over 2000rpms-by steps when it goes in this is where the main metering is operating and power valve.

You might have to change I/manifold or find the adapter.

Probably stripped the drive. Remove the entire seat (4 bolts) and flop it over is the easiest way to repair a seat
