Wiper help

[Backwoods]

Hey fellas, I have a 79, and I only have one speed on my wipers,I did ground the wiper switch but it didn't help, and they don't park, they stop wherever they are when you shut them off, how do I fix this?Thanks.

intermittent or 2-speed wipers? Do you only have low speed or high?

Check the connectors for corrosion.

Clean and resecure them.
