.GM uses a circuit board in the wiper motor to control the delay. There is no delay built into the switch. You can wire it to control the universal motor, both speeds, and park. It is possible to wire it to give a pulse function, through the washer circuit using a relay to shut off the park circuit long enough for one sweep of the wiper blades. You can do this, and still keep the washers functional if you like.Last edited by enjenjo; 10-15-2010 at 08:03 AM.
Anyone can restore an old car, it takes a man to cut one up
