I've been involved in an epic battle with my power windows (96 F150 EB) for a couple of weeks now, trying to get them to work. There's power to the fuse panel, but nothing to the doors. My locks work fine, and the windows will occasionally work for a minute or two if I hit just the right pothole. Both doors are dead, except for the occasions mentioned above.

Wiring looks excellent, and it's always been a pampered desert truck so there isn't any real corrosion anywhere.

Is there a dedicated relay for the windows somewhere?
Should I consign myself to a life without drive-thru's?
Anyone have any ideas?

 

maye the window motors are burned up. even when they are shot they will still work occationaly look into pulling them off and bench testing them to see if they will turn in not... part with about $200 dollars and get a new set. i think mine costed like 65 for passenger and 85 for the drivers

 

yeah it is probably bad motors also y you have a blazer for a lawn ornament you know they are prone to rust

 

Im not sure about the relay's but I know you should check the wiring where it goes through the door into the cab. Ive heard some guys say the wiring looked fine, but it ended up being poor right there.

Regarding the blazer, I gotta admit they were pretty cool when they had a 6.2 diesel in them!

 

It's not the motors, I checked them. There's no power to the switches normally. There's no open circuits that I can find in there. I'm determined that it has to be either a relay sticking or a bad connector somewhere under the dash.


The Blazer was Grandpa's truck - one of these days when I have some money to spare it'll get restored.
