My cobra only has one wiper on drivers side...I suspect wiper motor went bad..any idea what kind it could be. One shaft going to drivers side wiper, only one speed, light grey plastic cover and has + - and s wires, CE 110 printed on housing. Will be a pain to take out, when I put 12 v test light on positive..Has power, even if inside switch is off..do you know possible what brand of wiper motor could have been used? Any easy way to test motor while still mounted on car ...if using volt meter where would I put black and red leads...might be wiper switch but not sure if I'm testing it right...thanks in advance for any help.
