toyaholic Posted March 13, 2015 Share Posted March 13, 2015 hello there, i have been searching around for a couple of weeks and have come up with a couple of obvious maybes but was wondering if anyone had any solid troubleshooting tips or info. i turned the wipers on my wifes 2010 forester on after cleaning the windshield one ice/snow mix morning and the wipers were stuck and i thought i had turned them off. i took off waiting for the defrost to clear the windshield and when i went to turn them back on i realized that i had never turned them off. so now the intermittant and auto stow functions do not work. the low and high speeds work just fine. any help or insight is greatly appreciated. jess Link to comment Share on other sites More sharing options...
gbhrps Posted March 14, 2015 Share Posted March 14, 2015 (edited) toyaholic, From what you describe, I suspect that you've fried part of the wiper motor's wiring, or the circuit board inside the combination switch (the wiper switch/ stalk on the right side of the steering column). A check of the FSM shows that there are 3 different combinations of electrical connections that can be made to run the wiper motor. One pair of connections is for the low wiper speed, another set runs it at high. The third combination of four connections parks the wipers, suggesting to me that in this sequence the motor must reverse itself to park. In this last combination, one connector is used for the first time and I suspect it is the connector that is used for the intermittant setting. I'm going to put the diagnostics page for testing the motor at the bottom of this post. If the motor doesn't test out as described in the procedure, the motor needs replacing. If it does test out correctly, the combination switch has fried part of its circuitry, and the entire switch assembly needs replacing. I'll put the diagrams for its removal here as well. In either case, I'd be getting a used one from a wrecker, as I suspect neither one is going to be cheap from the dealership. Good Luck!
