steve..the hq to wb series of wiper motors are the biggest pos since the eh wiper motor..problem is they are in a position that allows them to get wet and the water goes inside to the bottom where the bearing is and they seize..another problem is that because they dont get used they seize as well..
a tip for all is to use your wiper motor on a regular basis wether its raining or not..especially run them after washing the car.
if you are in need of a second hand one i sell good tested working for $95 or rebuilt for $195..usually this is on an exchange basis but for mysandman humans i will do them outright no exchange at this price.
