Remove the terminal block by inserting a small flat tip screwdriver into the side of the terminal block on the back of the switch. The window switch terminal block on the back of the switch is held in place by four tabs (two on each side) which fit into detents in the switch body.Sometimes however, the switches are worn to the point that the switches will not operate smoothly and they may have to be replaced. Most of the time, the window switches can be disassembled, the contacts cleaned, and the switches reassembled and they'll function just like new switches. The majority of problems with window switches are the result of dirty contacts. If you wish to try and clean the window switches, refer to the Window Switch Repair section below. You can replace the switch or you can disassemble the switch and clean the contacts. If the measurements taken above are not within specification, the window switch is bad.When the window switch is depressed in the close direction, you should real a low resistance from terminals 1 to 3 and terminals 2 to 5.When the window switch is depressed in the open direction (see diagram above), you should read a low resistance (less than 1 ohm) from terminals 1 to 4 and terminals 2 to 3.Using an ohmmeter check the window switch as follows:.

Proper voltage verifies the power supply and wiring up to the window switch is good.

Using a voltmeter, on the switch plug, check for approximately 12 VDC from terminal 4 (RD/GN) to ground and terminal 5 (RD/BL) to ground.

Turn the ignition switch to the ON position.

Remove the window switch to be tested from the door panel.

For instructions on removing the door panels to access the power window motor go to: For instructions on removing the door panels to access the power window motor go to:Ĭheck for proper voltage at power window motor plug when window switch is depressed. The easiest way to test this is to take a known good switch (for example if the driver's window is working fine) and plug it into each of the switch locations for the passenger's window to see if you can get it to start working. So, if you have a problem with the passenger's window it could be either side.

The passenger window switches (one on each door), are wired in series with the driver's side switch supplying power to the passenger's side switch. So, we will first troubleshoot the switch and in the process check the wiring up to the switch. The most common problem of these is the power window switch. If your window problem is only on one side, the cause is most likely a bad switch, bad wiring, or a bad window motor. On late model 944s, it's located on the Central Electric Panel (G7). On early 944s, the power window relay is located on the lower left side of the center console near the DME computer.

When you install the jumper, you don't need to turn on the ignition switch to test/operate the power windows. If you suspect that the power window relay is bad, you can remove the relay and jumper terminals 30 and 87 to power the window motors. So, if the problem is only one one side, the relay is good. If the power window relay is bad, neither window will move. Late 944s (1985.5 and Newer) - Fuse 4 (30A), Central Electric Panel.So, if the problem is only one one side, the fuse is good.

If the fuse for the power windows is bad, neither window will move.
