96 windstar wing windows won't close

I’ve replaced switch,old one would work about

every 100 clicks,new one does absolutely nothing motors work fine when switch works.

It’s getting cold,how should I trouble shoot

to pinpoint issue ?

Inspect your switch installation job very closely and make certain the switch IS good.

If all is good there, then there must be a wiring fault between the switch and the window motors.

This means tracing the wiring using a continuity tester at different points.
