landriopa Posted September 28, 2018 Report Share Posted September 28, 2018 As I was driving my 63 Avanti home from the Studebaker Swap Meet in Dunkirk Friday, I caught up into a monsoon. I quickly realized that the wipers while prefect for a light rain were no match for a heavy rain. They work properly and reset but have only one speed. No matter where I turn the knob, the wiper speed does not seem to increase. Is this a wiper motor or a rheostat switch problem? Link to comment Share on other sites More sharing options...
Gunslinger Posted September 28, 2018 Report Share Posted September 28, 2018 Probably not the motor...it only does what the switch tells it do. I would first check that the knob is tight on the shaft...it's held on by a hex screw. That could need tightening. The switches themselves rarely go bad but it can happen.
