Electric windows stop working until key turned???

Hello,
The electric windows on my 2007 JK will suddenly stop working in one or the other direction - up or down. When I pull over, shut the vehicle off, then re-start it, they work fine again. In two instances to test this, I pulled over just to shut off and restart the vehicle; the vindows immediately worked fine. I am sure this is a computer issue as the door locks sometimes decide to lock at odd and inconsistent times. Can this be simply resolved at home?

Thank you for your help,
JK Justin with XJ too

You may want to disconnect your battery for 20 or 30 minutes and see if that helps. If not, you may need to have it flashed.

ditto. Reset the computer first. 30 second disconnect is really all it takes - but this is always a good time to clean, inspect and do other PMs while its disconnected, so usually when I reset its for at least 20 minutes...

My 2008 JKU does this every now and then, too. Battery is within a year old new and it still does it. It is the switch itself that is doing it. My original switch LEDs in them went out and mine started doing it. Replaced the switch and never had the issue until these LEDs went out now. I just deal with it best I can. Doesn't do it too often so no harm for me.

The circuit breaker (CB 1) that protects the window circuits/motors will disconnect when overloaded, and will self-reset only after the Jeep is shut off.

I would look for a reason the circuit is overloading.
Do the motors sound like they are straining or bogging down?

Mine dont. I keep some lithium grease on them every once and a while to keep strain off of motors.
