'66 wiper issue - The 1947 - Present Chevrolet & GMC Truck Message Board Network

psycotruckr · 10-05-2010, 02:14 PM

does anyone have a wiring diagram for a '66 panel, would even settle for a pu one. My motor has 5 wires going to it and as far as I can tell none of them is hot. I would be happy if I could even make them run with a toggle switch. Any help would be appreciated as aggravated as I am now I am about ready to run a string out the window. $40 for a switch and $160 for a motor is more than I am ready to spend till I can atleast understand why it does not work now. Thanks

I dont have a diagram handy but maybe I can guide you.

Hot wire from fuse goes to motor ( I think it is yellow), light blue wire goes to switch.

BTW do you have a two speed switch?

OK, I found one

I have a red wire going to fuse block, a jumper wirer going to two terminalals on the motor and a black and yellow and a black going into the harness

psycotruckr · 10-05-2010, 02:26 PM

yes it is a two speed switch with a washer bouton in the center

The harness is a new " painless wiring" harness. Had no trouble at all with wipers before changing harness

**Clyde65** · 10-05-2010, 02:43 PM

I am trying to remember mine......I believe the black and yellow go to the pump, the black through the harness should go to the switch. Have you called Painless? which harness did you get?

Looking at their 63-66 wiring harness diagram, page 27 figure 7.19 and table 7.4, does that help you any? I got it off their website

psycotruckr · 10-05-2010, 02:46 PM

They said as long as it was hooked up like the pic provided it "should" work. I guess we are down to part swaping

**Clyde65** · 10-05-2010, 02:52 PM

so you have it like they have stated right? maybe a dumb question but where is your switch? is it dangling under the dash? it needs to be grounded in the dash surround I think.

psycotruckr · 10-05-2010, 03:00 PM

everything is mounted like factoty, I did manage to get a single speed with a toggle , no park, no wash, will try a new switch next week I do have confidenece in harrness now. stranger things have happened than a part going bad on the shelf fo a few years, thanks for your help, your wiring diagram seam to be for a single speed motor though

**Clyde65** · 10-05-2010, 03:08 PM

yes your right, single speed. If you need anything else, PM me and I will look at my truck at home...might be with me at the office latter this week though.
