I have a 2003 6l diesel. The windows will work sometimes and then they quit working. Also have had a problem with the backup sensors doing the same thing. They will go for a few days working fine and then they quit. Any ideas would be appreciated.

 

i lost the power to the rite rear window on my 03, turned out it was the master switch on the drivers door...

not sure about the reverse sensor other then maybe trying unplugging them and cleaning the contacts...

 

Just drive it on the days they all work.

 

Oaky seriously, intermittent crap is hard to find.

Bad ground?

A relay that is tired, but works on occassion?

If its temp related, it could be something with a poor conduct say when cold, but heat expands it enough to make contact.
A wrire thats worn thru the insualtion, and bumps jar it free and it works, then it goes back to being shorted out.

Could be a million different things really.
I would get a multi meter and start checking wiring and relays to start with.

 

Hello everyone, I would start at the door switch.
