Diagnosis of faults in electric windows (Opel Zafira A)

Note. Depending on the nature of the electric window lifter malfunction, the sequence of checks and the range of elements to be checked differ. Therefore, the sequence of troubleshooting is given for two typical cases of electric window lifter malfunctions, from which you choose your case.

To complete the work you will need a multimeter.

All electric windows do not work

1. Check fuse F15 of the fuse box located in the passenger compartment of the vehicle (see "Fuse and relay mounting blocks"). If necessary, replace it. Turn on the ignition (turn the key in the ignition switch to position II) and check the operation of the electric windows. If the fuse burns out again, there is a short circuit in the electric window circuit that must be repaired (see "Checking and repairing electrical circuits"). On cars with only front electric windows, also check fuse F20 of the mounting block located in the car's interior (see "Fuse and relay mounting blocks"). If necessary, replace it. Turn on the ignition (turn the key in the ignition switch to position II) and check the operation of the electric windows. If the fuse burns out again, there is a short circuit in the electric window circuit that needs to be fixed (see "Checking and repairing electrical circuits").

2. Check the electric window control unit (see "Electric window control unit - check and replacement").



3. Check the electrical circuit of the electric windows (see "Checking and repairing electrical circuits").

Rear electric windows not working

1. Check fuse F17 of the mounting block located in the car's interior (see "Fuse and relay mounting blocks"). If necessary, replace it. Turn on the ignition (turn the key in the ignition switch to position II) and check the operation of the electric windows. If the fuse burns out again, there is a short circuit in the electric window circuit that must be eliminated (see "Checking and repairing electrical circuits").

2. Check the electric window control unit (see "Electric window control unit - check and replacement").

3. Check the electrical circuit of the rear electric windows (see "Checking and repairing electrical circuits").

One of the electric windows does not work

Note. Below is a situation where the electric window does not work either from the control unit or from the button on the passenger door. If the electric window does not work only from the button or only from the unit, then the fault is in either the button (see "Passenger door power window control keys - checking and replacing"), or in a block (see "Electric window control unit - check and replacement"). If they are in good condition, then the fault is in the wiring to the key or to the block (see "Checking and repairing electrical circuits").

1. If the driver's door electric window does not work, check the electric window control unit (see "Electric window control unit - check and replacement").



2. Disconnect the wiring harness connector from the gearmotor (see below).

3. Connect the power window control button or the power window control unit (on the driver's door).

4. Turn on the ignition, measure the voltage with a multimeter in voltmeter mode (should be within 11-14 V) between terminals 1 and 4 of the wiring harness connector (the numbers are printed on the block body, the colors of the wires are red and brown). If there is no voltage, then the electrical wiring from the fuse box to the gear motor is faulty (see "Checking and repairing electrical circuits").

5. Measure the voltage between terminals 2-4 and 3-4 with the electric window control button pressed in different positions. When the button is pressed down, the voltage should be within 11-14 V on one of the pairs of contacts, and when pressed up, on the other. If there is no voltage, the electric window control circuit is faulty (see "Checking and repairing electrical circuits").

6. If the voltage test does not reveal any faults, then the electric window lifter is faulty and must be replaced (see below).
