Where does the delay switch go on a wiper?
The delay switch mounts in the same place as the non-delay switch, the wiper motor mounts identically, and you need to connect a few new wires between the switch and the wiper motor.
What causes long delay between wiper motor cycles?
The DELAY switch position indicating the longest interval between wiper motor cycles is the switch position with the highest resistance resulting in low voltage on the wiper switch signal 1 circuit. The low voltage charges the capacitor slowly causing a long delay interval between wiper motor cycles.
How does a low speed windshield wiper work?
If the wiper switch is moved to the MIST position and held, the windshield wiper motor will operate in the LOW mode until the switch is released. Windshield wiper DELAY operation is a low speed wiper motor function with a variable delay interval between the wiper motor cycles.
How to change a delay wiper on a 1974 Buick?
The wiring diagram from the 1974 Buick Shop Manual is below, with the separate delay wiper harness indicated in red. Once I collect the three “delay wiper only” pieces (motor, switch, harness) the changeover is as simple as replacing the motor and switch with the delay pieces, and hooking up the new wiring harness between them.

Why do my windshield wipers stop in the middle?
What a bunch of horrible answers. The reason for the wiper blades stopping in the middle is that the stop switch, inside the motor assembly, is not parking the wipers in the required position. It is the new motor that is faulty. Was this answer helpful? simply remove the blades and replace at the start position at the bottom of the screen.
When did delay wipers come out for Chevy trucks?
A similar situation is what happened on my 1975 Suburban. Delay wipers were not available in any of the Chevy or GMC trucks until 1978, and in that year they did a slight redesign of the dash and they changed the wiring around a bit.
