My 68 has/had a 3 spd. wiper motor and switch in it. Can I swap a 2 spd.motor in its place or does it cause electrical problems ?? :shruggy:
You should be able to swap over to a 2 speed motor....you will need to change the switch to a 2 speed as well.
Also check the wiper transmission compatibility......not sure....but the transmission may also need to be changed.
electrically is just about get the motor and harness, and change the switch
mechanically, sorry, I know just about 3rd gens, where the main linkage and crank changes allong with a parking cam used to hide wipers down the hood for 2 speeds ( 3 speeds parking cam are built in )
