I have a 1998 Ford f-150 w/ the 4.6 V-8. My issue is the passenger side window. I have replaced the motor, checked all wires & switches driver side & passenger side. They are ok. I changed the (Jim) module that plugs into the fuse box. The motor will only run one direction. A Ford Tech has spent more than 4 hours on the problem & can't solve it. Any Answers?
