Hi Scotty, I have a 2010 Grand Caravan SE with a 3.3L that has been converted into a wheel chair accessible van at an additional cost of another 20,000 within a week of purchasing brand new, so to say the least I want to keep this vehicle going as long as I can. The power windows (driver and passenger) (the rest work all the time) on the van do not work when the weather gets 75 deg. or higher and sometimes more times than not they will work if I open the drivers door and operate them while the door is open. If it is cool or cold this problem is non existent and they work just as they should. So my question is what possibly could be the problem here? Is a computer issue the culprit or a window control unit? Thx Greg
usually its broken wires in the door harness where it folds
Maybe is too hot and the rubber sticks of swells from the heat. Try to lubricate all the sides that the window rubs on and see if that makes any difference. Could be something that simple.
