Boxster passenger window will not drop with top unlatched--------

[kamran66]

Hi folks, my passenger side window regulator cable broke...I found a used regulator which I installed today..everything works such as the 1/2 inch drop when the door latches are opened..the up and down travel works good also only issue is that the passenger side window does not drop when the top is unlatched...the driver side however does. I guess with the driver side working we can rule out a bad micro switch in the top latch...correct? Does anyone know what maybe causing this? Can it be a window adjustment issue? Any help is greatly appreciated.

EDIT: I changed the regulator and motor as an assembly....

I would change back to the old motor and see what it gives, the donor motor exhibited probably some shortcommings.

I was thinking the same thing...although I don' t think the motor has any switches in it..but with out knowing how that top circuit works, it's worth a try.

"... I guess with the driver side working we can rule out a bad micro switch in the top latch...correct?..."

That is correct. If one side window is dropping the normal aprroximately 4 inches, you can rule out the one of the two microswitches inside the latch assembly that triggers the window drop. Also, the other microswitch in the assembly has no effect on the window drop.

The problem lies elsewhere.
