Engine quits with electric windows

[BIG1RED9]

1987 Wagoneer, 4.0

My electric windows were moving very slow to close. At least a minute to close one of them. I kept on the switch and at about 3/4 of the way up the engine quit and had no response from the key switch for about 30 seconds.

I tried this a second time to see if it would quit and it did.

So I am trying to confirm if it is the electric widows causing this or do I have a different issue.
Thanks

The OEM wiring was undersized on these and is overloaded at the ignition switch. I replaced and by passed the ignition switch / key wiring that powers the windows and HVAC blower motor and some lighting with a 30 amp dash toggle switch on mine years ago and beefed up the wire sizes. Mine is an 87 Wagoner.
My windows still move super slow, which is in part a lube issue (PITA) and Cruiser54 has always suggested it is also a poor OEM ground issue he covers on his website. I never got around to fixing the ground issues.

First thing I would do is get a meter on the wiring. Measure from the battery to the positive going to the windows and see if it's dropping voltage through the ignition switch. Then check if it's the ground side having issues.

Sounds like a dead short somewhere the window wiring. Slow windows can be sped up by cleaning the tracks and the mechanism. The cleaning does nothing for electrical.
