OK, I went out to the car to do some more tests and I really pushed the wiper from one side to the other and it wouldn’t budge and I kept pushing until it kind of unseized.
Now it’s sweeping back-and-forth so all the electrical is good in the motor and it is working but it seems weak… Like it doesn’t have enough torque to pull the wiper over the glass and stops in the middle sometimes and then I can kind of push it again and get it going
If I raise the arm so it’s not on the glass it will turn back-and-forth over and over again without stopping… But while I’m driving I can hear it being very loud, the motor is making a buzzing and clicking sound.
Does this sound like something I can disassemble the motor arm and clean the shaft and lubricate or just buy another one and replace the motor?
Thanks everyone
