Hello all,
Trying to figure out the correct wiring for the non a/c blower motor. Wheere does the heavy guage brown wire go to? Also, the wiper motor has four wires (ltblu, dblu, blk, blk/yel). Where do they tie into my switch? I'm trying to bring this classic back from the dead and any help will surely be appreciated. Thanks to all

Elree's diagram help?

Thanks. As per the painless instructions I am testing all circuits with my 10 amp charger first. Is this why I might not be getting function from the wiper motor and the blower motor? Any idea where the white wire from the drivers side trunk area connects? It looks like it should power or ground the dome light somehow. Thanks again.

What Painless harness do you have?

#20102 18 circuit. I tried wiring the wiper motor as per the diagram but something is wrong because the blk/yel power wire is getting hot and I keep blowing fuses. Man, I'm stumped. I really appreciate all the help

This illistration (http://home.neb.rr.com/postmodern/wwpump.jpg) is by Coppertop, sure hope it's not a problem to referance it. This (http://www.chevelles.com/showroom/tempwprwr.jpg) is a pic of a 71 wiper switch. The wiper motor gets the yellow wire #975 (black/yellow in the pic), black #976 and lt-blue #973, the washer pump gets yellow #975 and blue #974. The switch gets lt-blue #973, blue #974 and black #976. The switch also needs to be grounded. Hope this helps.
Wire as shown if it doesn't work post back.

Man, oh man...I am absolutely stumped. I tried all of the suggestions and still no luck. What is even more frustrating is that the wiper motor is one of the few things that used to work!

You can test the wiper motor. Using alligator clips, or some other means, ground the motor terminals that get the black and lt-blue wires then apply power to the center, yellow wire, terminal. The motor should run in low speed. Disconnect the black terminal ground, the motor should run in high speed. Reconnect the black terminal ground, motor in low speed again, disconnect the lt-blue terminal. The motor should park. If the motor operates as described the problem is with the wiring or switch, if not the motor is the problem.

Thanks. I'm going out there right now to test it as per your instruction.
