How do you diagnose a master window switch that works sometimes and sometimes it does not work.
Sometimes the master control window switch works and sometimes it does not work.
which leads me to believe there is an electrical problem. How doe you diagnose this
the wiring harness through the door would create an intermittent condition...sometimes there sometimes not...when the weather gets cold things contract...warm they expand...will shop for a harness for the driver's side...I imagine~
okay here's a USED one for fifty bucks....we can do better...rockauto.com will serve~ with reasonable prices~
Judge_roy. Thank you for your answer. this wiring harness looks like a non mechanic like me can install it correct?? From your answer I assume that you are talking about replacing the wiring harness on the drivers side left front door. Is that door panel easy to take off and put back on???
You will have to consult the Technician's Handbook on that one...could check a few blogs...let you know if any of the info escaped from the tech manual~
it's the switch's connections, not the wiring harness. Over time the get a coating. Pull out the switch and clean all the contacts. This is usually the problem. They switches also go bad. I replace mine with a new one for $100 (do gogle search).
of course TEST any component you may be replacing~
