Terminal marking
The terminals on the motor are standardized as follows. The numbers in bold are the standard designations, the numbers in brackets (...) are Ford designations.
Terminal 31 (3) - this is a terminal for connection to the body (in general in the electrical equipment of vehicles).
Terminal 53 (2) - receives the voltage for the first wiper speed.
Terminal 53a (5) - supplies positive current (+) for resetting the wiper blades: the motor is still energized via the sliding contact while the wipers are running in the home position, if the driver turns off the wipers.
Terminal 53b (1) - supplies voltage for the second wiper speed (parallel winding).
Via terminal 53e (4) the wiper motor is braked when moving backwards after switching off, so that the wipers do not leave their stop position.
Wiper motor check
First of all, find out if the wiper motor is working and if the electrical supply system is in order. To find out, do the following:
Unplug the multi-pin connector from the wiper motor.
Apply voltage using two auxiliary wires (+) and mass (-) from the battery to the wiper motor.
Lay one wire from the positive pole of the battery to terminal 53 (2) or 53b (1).
Run the second wire from the negative pole of the battery to terminal 31 (3) engine.
Now, depending on the terminal used, the motor should run in stage I or II. If the engine does not run, then the engine or the corresponding stage is faulty. Remove the wiper motor see point 23.5.
