Question about 1987 Subaru Gl 4WD

1 Answer

1987 Subaru GL Wagon windshield wipers are inop in all modes.

This is a multi-level problem because I have already replaced an inoperative motor assembly and the problem is still not solved. I have power to the motor, no fuses were blown and I can hear the intermittent module clicking at regular intervals with no result at the windshield. Neither low or high speed works either. According to the wiring diagram this motor grounds at the case and this checks out as a good ground. With the plug connected to the motor, three of the four leads give me a voltage readout of battery voltage (just under 12 volts) and I suspect the fourth lead is to give the intermittent module a position indication. I am not sure of my test results because I do not have correct information from my limited repair manual to properly interpret the testing I have completed. I need more specific test information in order to complete my repair.

99 f350 super duty, wipers would only come on sometimes. I changed wiper motor now they still don't work


The generic electronic module (GEM) responds to the windshield wiper control commands by interpreting inputs from the steering column multi-function switch. The speed dependent wipers will compensate for the extra moisture that accumulates on the windshield at higher speeds, except when the multi-function switch is in the INT 1 position. At higher speeds, the speed dependent feature shortens the delay between wipes when using the variable interval wipers. Delays will automatically adjust at speeds between 16 and 105 km/h (10 and 65 mph).
Testing should be done before replacing any parts . And if you don't know about (GEM) Control module controlled system's your best bet , take it to a qualified repair shop . The first place to start trouble shooting these systems is with a scan tool that can read GEM module codes .

2001 Subaru outback driver side windshield wiper goes to far to the outside tears up the end of the blade - ideas please


I have the same problem with a 2001 Legacy wagon. The problem is not as simple as the solutions above. Mine are adjusted to park as low as possible when off. Even so, the blade on the drivers side goes all the way off the windshield. The Subaru dealer wants to replace the whole wiper blade transmission for about $450. Looking online it seems to be interconnecting arms and pivot points that connect the motor to the wiper blade arms.

Windshield wiper switch inop., except when pushed for washer.


My solution is as follows: Place a 1K-OHM resistor (Radio Shack Part # 271-1118) between the orange/white stripe wire (power) and the green/yellow stripe wire of the mullti-switch terminal block of the steering column. This provides the speeds - normal and intermittent speeds but not high wiper speed. Less than a $1 solution instead of the costly BTM replacement.
