1977 Chevrolet pickup wiper switch with delay can you replace it with a wiper switch with out delay?

Yes in theory but why would you want to, the two units cost the same.

Also, buy Rain-X and clen windshield inside and out and apply it

• this will delaythe need to have the wipers on and helps alot in

heavy rains Also buy rain-s windhsield washer to fill the washer tubs with. I traveled across country several times the rainshield made a HUGE difference
