wiper motor question??

two speed wiper motor in ebody. car sat for twenty five years, recently restored, with the exception of the wiper motor. Motor works, but wipers are very slow, only work in one speed and will not fully go back into park> Is it a motor problem? Switch? Ground? ballast resister thing??

Thanks

i would say after all those years of sitting it's a combination of all except the ballast. re-ground, take switch apart and clean, try again!

you think more the switch than motor?.

after 25 years it could be anything or a combo of all. if it were me i would start by re-grounding the motor and then switch. those are just the easiest and most likely places to start.
