When power windows don’t raise or lower, it is likely because the regulator inside the door has gone bad. Replacing the regulator is the only repair you should have to do, as this part controls all the functions of electronic windows.
Before you can perform power window repair, you’ll need to gain access to the regulator which is found inside the door panel. Remove this panel by taking out the screws that hold it in place. You may have to remove some additional trim, depending on how your vehicle’s interior is designed. Take these parts and then set them aside along with their fasteners so that you can replace them when the job is complete.visit us now!
Disconnecting the Old Regulator
Locate the bolts that hold the regulator in place; this could require you to lower your window. Remove these bolts with a socket set and then set them aside. Disconnect your negative battery cable and then remove the wiring harness that is attached to your regulator by loosening its connectors. Have another person hold onto the window glass while you’re doing this, so the panel does not fall out and shatter.
Remove the Glass
Once your regulator is removed, there will nothing holding your window glass in place. You will need to remove it before continuing with the next phase of power window repair. This requires two people, one on the inside of the door and one on the outside. The person on the outside should lift the panel up slightly at the top,thereby tilting the glass at somewhat of an angle. This is done while the person on the inside steadies the glass by holding onto it very lightly. Once the window has been taken out completely, it can be set aside until it is time to replace it.more window info from http://www.nseavoice.com/cars/toyota-camry-rav4-broken-power-window-module-can-start-a-fire-1005981.html
Replace the Regulator
Take a new window regulator that has been purchased from an auto parts store and remove it from the box. Attach the bolts that held it inside the door frame first. Once these are securely in place, you can then attach the wiring harness back to the regulator as well. Insert the glass panel back into the tracks on either side of the window frame and situate it into position. Once it is properly seated, check the window’s operation by pressing up and down on the power window switch. If it does not operate properly, this indicates the wires are not attached correctly. In this case, recheck them and tighten if necessary.
Once you have confirmed the window is operating properly, it’s time to put the door panels back into place. Tuck the regulator neatly into the space provided, taking care not to let any wires hang out. Use the screws you took out earlier to replace the door panel and any trim that was also removed. Check the operation of the window one more time to make sure everything has been performed correctly.
Expect this task to take around two to three hours, especially if you have never done this type of repair work before. While it is a time-consuming task, replacing the regulator is nonetheless a somewhat simple repair that can easily be performed by those with little mechanical experience.
