Can You Repair A Window Switch

Power window not working

How to diagnose and ready ability window non working

Power windows not working?

When you have a power window not working condition, most DIYers automatically suspect a bad power window motor. That'due south usually not the case . If you accept a power window not working issue, the error is usually a broken window regulator, bad window switch, or a problem in the ability window wiring.

Passenger window non working

Most vehicles have a lockout switch on the master switch to prevent rider windows from opening if the driver locks them out. If your passenger windows don't work, double check to make sure you don't have the lockout switch turned on. If the switch isn't set to the lockout position, and so proceed with the diagnostic steps below.

Window goes down but not up or window goes up only non downward

If you desire to set up your power window you lot MUST understand in that location TWO CONCEPTS:

First: All the wiring for driver'southward and passenger's windows runs through the principal switch. When passenger windows don't piece of work, simply the driver's window does, chances are high that you've got a bad master switch in the driver's door or a cleaved wire in the driver'southward door swivel area.

Second: Ability window motors only have ii wires. When yous operate the downward cycle on your power window switch, it provides + ability and – footing to the power window motor. When you lot operate the up wheel, the switch reverses the polarity on those same two wires. So if the motor works in ane direction just fine, but not in the other direction it'due south near NEVER the motor—it'due south the switch.

Power Window goes down but not up

Aside from not working at all, a power window that goes downward just not up is the second almost common complaint. If you understand the betoken I've made in a higher place; if the window goes downwards, that confirms that wiring to the window motor is good and, in about cases it confirms the motor is good (although rare, sometimes a motor can work in one direction and non the other).

Examination a power window motor

Disconnect the electrical connector from the regulator motor. Gear up your multimeter to DC volts. Connect the red and black probes to the 2 wires on the wiring harness connector you just removed. Then turn the ignition key to the RUN position. Toggle the window switch up and down. If the meter reading toggles betwixt +12 volts and -12volts, the switch is expert. The trouble lies in the window regulator.

Toggle the window switch and check meter to run across if information technology switches from +12volts to -12volts

Power window voltage toggles but window doesn't motion

If you're seeing the toggling voltage, the problem is in the window regulator. It's either a bad motor or a cleaved regulator that's causing the motor to stall. Reconnect the electrical connector to the motor and try operating the window. If the motor is skilful, you should run into some movement or hear some dissonance coming from the motor. If you see motility, the regulator is usually at error. If y'all have a cable operated regulator, replace the entire regulator.

If the motor shows no movement, it'south probably bad. But once again, if it's a cable regulator, replace the entire window regulator.

No voltage or footing at ability window motor

If y'all don't see voltage and ground at the power window electrical connector, the problem is either the master switch or a wiring harness issue. Catch a wiring diagram and check for power and ground coming into the master switch. If yous don't see power and footing, caput for the wire packet in the driver's door hinge area. Since that door is used well-nigh often, those are the wires about probable to intermission due to the constant flexing. If you notice an open or chaffing, repair the wire and you should be back in business.

If the voltage does Non toggle, and then it can only be two things: Bad switch or broken wire. Wires suspension nigh often in the swivel area of the door.
