Many vehicles with capability windows carry the convenience of a masterly bridle switch at the Chauffeur’s side that lowers or raises windows, and maybe an additional switch that disables characteristic window check switches. The state line provides a reversible motor--and normally a relay--plus a fuse or breaker for Everyone window line, moreover to the usual relay and succession breaker or fuse. This setup allows other windows to function all the more when electrical or mechanical problems disable one of the windows. These steps Testament relieve you allot the hot potato, if one or all the capability windows in your vehicle seem stuck. You demand correct basic generous of electricity or the ambition to memorize basic troubleshooting procedures.
Instructions
1. Turn the ignition on nevertheless don’t derivation the engine. Guide the windows from the crackerjack driver's seat switch. Provided none of the windows grindstone, evaluation the leading fuse or breaker for the complete ability window succession. Provided solitary one of the windows is inoperative, life To pace 3.
2. Go To pace 7.4. Turn the ignition on but don’t start the engine. If voltage is reaching the relay, replace it. If there is no voltage reaching the relay, there is an open or short at the wire between the relay and the main fuse.
3. Check the circuit fuse or breaker at the inoperative window. If the fuse or breaker is okay, go to the next step. If you can hear a humming sound as you press the switch but the window does not operate, either the motor is bad or its gearbox may have broken teeth. Test the leading direction relay using a test light. If voltage is coming out of the relay, there is an open or short at the wire feeding power to the other switches. If no voltage is coming out of the relay, use the test light to make sure voltage is reaching the relay.
Using a multimeter, check the master control lockout switch for continuity. If there is no continuity, replace the lockout switch. With some vehicle models, problems at the lockout switch can cause both rear windows to fail.
5. Try the switch at the inoperative window and check for continuity using a voltmeter. If there is no continuity, replace the switch.
6. Check for voltage at the switch using a test light. If voltage is not reaching the switch, there is an open or short between the incoming wire and the fuse or breaker for that circuit power window.
7. Take off the trim panel from the inoperative window. Check for voltage at the motor with a test light while pressing the switch. If there is no voltage, there is a short or open at the wire between the switch and the motor. If the circuit is equipped with a relay, test for voltage reaching and coming out the relay. Make sure the relay is working properly. If voltage is reaching the motor, go to the next step.
8. Detach the window from the regulator and inspect the regulator mechanism by moving the window up and down by hand. Make sure nothing restrains the mechanism. Also, inspect the motor gearbox. Replace any parts as necessary.
