Weird Power Window issue ! HELP ! Please

On my wifes 96 Jeep G/C Limited.... on a warm to hot day the power windows wont work ( none of them ) ! In the early mornings the windows will work fine.... when she gets off work @ 3-4 in the mid-afternoons the windows will not work ! She say it may take 3-4 minates and the windows will start working on their own.... or she seems to think by slamming the door @ times will make the windows work alittle faster ? She said it started doing this late last year, and then cold weather came & the problem went away, but now it s hot again and the problem has came back !

Any help at all I m Thankful !

I had a problem like this in my 93 GC Laredo... the kick panel on the drivers side there are wires in there that go thru the door on the drivers side, i had to take off that kick panel and check for crimped or cut wires, i did find some and i havent had the problem since. check that out, quick easy fix for us.
