Chosen Solution
Hi, I have a 1984 Isuzu Trooper 3dr. Lately I’ve noticed that sometimes the wipers would randomly turn on when I started up the car and simply stop in a random position. Then I can’t get the wipers back down unless I pull quite hard on both of them. The motor is drawing power as well (car had a voltage gauge for some reason) and it’s honestly irritating. I’ve replaced the wiper motor 3 times already and since it’s the rainy season over here I really don’t to be stuck without wipers in heavy rain again. Is there anything I can do other than replace the motor yet again? (As if anyone here actually knows about these 1st gen Troopers…)
@ngs765 could be wiper linkage problem. If the linkage binds it will require more work from the motor and like you said a motor replacement does not permanently fix this. Check the linkage by removing the cowling just below the wipers.
Often times the headlights must be turned on for the wiper cycle to complete. It was a safety design protocol from the late 70’s. just a guess however.
