Electrical seat issue /questions/ HELP!!!
 

My 05 Yukon XL has full power/ heated bucket seats. The driver side seat just won't move today! Nothing will move, up/ down, forward/ back, lumbar or easy exit. The seat heaters for both front seats also doesn't work although the passenger seat still moves just fine. I know it has to be a fuse! right? but which F'n one??? They are so hard to figure out which runs the seat. If I pull out the one I think it is, both seats go dead. But when it's back in place, same thing. Passenger seat works except heat, driver...nothing! I've checked all connections and nothing is "blocking" the track.

Finally was able to get dealer service advisor on phone and when he nailed it! The wires/ harness under the driver seat were loose. I "fiddled" with the wires behind the seat while hitting the button and it came back to life!

Thanks for your help.
