GM wiper column switch?
I have a 1990 Chevy Astro steering column in my '34 project. I want to hook the non delay wiper control switch on to work with the universal, 2 speed wiper motor that I have.
I think I might read somewhere that this is close to impossible... Is that so?
I have all contacts with pigtails on the column.Last edited by staleg; 10-15-2010 at 12:50 AM.

.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

I don't need the delay.
I just want to use the switch lever to operate 2 speeds plus washer function. That's all.

Thank you!
But is the right edge cut off, due to the size of the drawing? Or is it just my computer?Last edited by staleg; 10-15-2010 at 07:41 AM.
