Hi,

In reading your email I see that the motor works on the down side,  of
the cycle.  Have you tried jumping the power connector directly, to
bypass the switch?  I have the power regulator of mine apart, and I
don't see why it would jam only one way.  BTW the electic motor housing
attaches to the window regulator housing via a double ended rubber
connector with a D shaped spring steel insert.  They need to be sprayed
with Rust inhibtor or the like with a straw that comes with it, like WD
40, and carefully work the two housings apart with a pair of flat tipped
screwdrivers.

Sincerely,
