On the ford ranger wiper motor not working, this is how u fix it. I am a licenced autobody mechanic for mercedes and my son bought a ford ranger and of course the wipers were not working-neither did the dome light and door chime.I told my son too replace all fuses ,switch and motor. And still nothing.Remove radio there is a pcm in behind- ours was unpluged. When we plugged it in the door bell would not shut off and the dome light stayed on. In stead of unplugging the pcm remove the light if wd40 does not work on the door latches. And to stop the door bell ringing remove the plastic cover around the ignition and their is a single wire with a blue connector just remove the wire it is the wire closest to the key and tape up the end and problem solved guarenteed . my email is [email protected] I will walk u through it .
When that many things malfunction I would check all power distribution fuse units, grounds, wiring harness, and instrument cluster wiring. This will be a major undertaking and should be referred to a qualified shop.
