Driver side power seat will not move.

[2kv8]

Recently I noticed when I went to move the driver side seat forward it would only go about a 1/4 inch and the motors winds down and stops. I looked under the seat to see if anything is under it or something had fallen in to the track but I can't seem to find anything. The seat will go up and down with the switch it just doesn't want to go forward. Any ideas?

Lube the rails. If that doesn't help then pull the seat out and lube the rest. You may be able to apply 12V to the motor to see if it works or if you can detect a bad spot on the commutator or worn out brushes. If it's the motor I'd look for one at a junkyard from a vehicle that still has closed doors & windows up so it isn't as exposed to the elements.
