Power window issues.

[math 427]

I have a 2005 mercury mountaineer and the passenger front door power window will only go up, I have replaced the motor and regulator and all fuses seem to be ok, i'm stumped? Thanks for any info!

switch?

checked the switch seems to work, the switch on the drivers side will not work it either. However I sarted investigating more and it looks like someone spliced into wires underneath passenger seat to hook up power seat? possibly the problem?

Welcome to this forum! I've moved your thread into the stock 2002-2005 section. Check the wiring between the door, and the frame of the vehicle.
