2003 Jeep Liberty Sport, 92,000 km, 3.7l. All four power windows stop working while they are going up or down and then a few minutes later they work again. A couple of days ago the windows were down and they have not worked again so that the windows could be closed. Checked the ground, fuses, switches and cannot find any problem.
We had a similar problem with a 2000 Grand Cherokee limited. We just tried disconnecting the battery and, after about 5 minutes, reconnecting it. The computer must have re-set itself and now the windows and everything else works again.
