I switched to a two electric motor system. It has an electronic synchronizer that keeps the two motors running the same. I love the system.
I know on new trucks, there are no such thing as air wipers anymore. My 1985 Kenworth still has air wipers. When they quit, I'll change those also to electric. Good Luck, TomC
Can you give more info on where was your system from and how much did it cost?
