OK.. I will try and lube teh track first.... since that seems the easiest to do...
I will then try to access the motor to disconnect it... To clarify.... the access panel is on the Door? or near the speaker mount?
I checked tccoa.com... and couldn't find the pics you spoke of 'Coupe.... found 27 entries... none with the tear down you saw

I will continue to look though
And the seat belt is currently in the "locked" position, so all I SHOULD have to do to stop the noise (for the time being) is disconnect the motor.... I should not have to touch the adjuster, correct?
While the panel is off, is there a way to troubleshoot to see if the motor is in fact locking up?
I will attempt to do this tonight.... and I will keep you posted...
Thanks for all the help....
