Determining whether the window Engine has outside poor can helping hand contract fortuitous repair costs.
Ability windows are erect in most late-model automobiles; and when everything is powered, there is the practicable for a Engine to potency evil. When assessing a power window Engine, it is relevant to proof alternative sources for the complication before blaming the window Engine. Troubleshooting the issue yourself can too save you some clock, much provided you longing to bring the vehicle in to a mechanic. Provided none of the window buttons opens the windows, this does not automatically display a deficient Engine.
Instructions
1. Establish the fuse compartment that houses the fuses for the window motors. In vehicles manufactured after 1985, the fuse for the window motors is Fuse 4 (30A), and it Testament be in the central electrical panel. Cite to the owner's tome for your vehicle provided you retain dilemma locating the central electrical panel. Assess the fuse. Provided it has blown, interchange it with a fuse of the corresponding amperage. Check the window for system. On vehicles built before 1985, the fuse is Fuse 8 (16A), and it Testament be in the extra fuse panel. Test the power window relay. The power window relay is located on the Central Electric Panel in vehicles built after 1985 and typically on the lower left-hand side of the center console on pre-1985 models. Remove the power window relay and jumper terminal 30 and terminal 87.
Your owner's jotter Testament string the locations of all the fuse boxes in your vehicle. There are normally fuse boxes under the hood (labelled "Fuses") and one in the dashboard (typically on the driver's side). Newer cars have multiple fuse box locations, including the side of the center console or on the passenger's side of the dash.2. Test the power windows after the jumper is installed. This will tell you if the motor is still working or needs replacement. This will also rule out if there is something other than the motor at fault for the problem. If the windows work with the jumper installed, the motor is still functioning properly.
3. Check the window switch next. The window switch must be exposed from inside of the door panel in order to test it. Use a voltmeter or ohmmeter to check the window switch. Terminals 4 and 5 should read 12VDC or close to it. Terminals one-four (a connection of terminal one to terminal four) and two-three (terminal two to terminal three) should read less than 1 ohm with the ohmmeter when the window switch is open, and low resistance from terminals one-three and two-five when the window switch is closed. Low voltage indicates a problem with the window switch and possibly the motor.
