My windows won't go back up and the warning lites come on when I hit the window switch.Checked fuse in cab they were good.
Fuse links on fender check out to be good.
I lost my heater fan motor also.Any ideas??????????Is there a relay somewhere I'm missing?This is on a 91 d250

Check fusible links again..Im pretty sure they are on the same link

When the wife's truck had the same issues that you describe, I finally fixed the problem by cutting the cold wires to the windows and blower completely out of the fuse-block and powering them direct from fused battery=HOT.

She likes it this way a lot better because the windows can be opened/closed even when the key is OFF.

We never shut down an engine with a bunch of accessories still ON, so the fact that the blower can still be ON with the key OFF is not a problem.

I did the same thing on mine, I ran a 8 ga wire to the fuse panel, but I had to tap a light into the heater motor to remnd me that the fan was on
