Need help with parts for 1993 XLT 150 either the switchs have failed or the actuators are out, nothing happens when I use either the drivers or passengers switchs, no noise nothing happens 1st passenger side went out now both sides out, any help here what to check??

 

Check the fuse block yet? It's kind of a long shot since you haven't noticed anything else acting up. After that I'm inclined to fault the switch

The same circuit in my wife's Taurus is protected by a thermal circuit breaker, it was HOT to the touch. I found a short to ground by "wiggling" the harness pigtails near their respective device. Her problem was under the power seat.

Good luck, Mike
