Windshield wiper: 2 speed to intermittent

[gmachinz]

There is a black wire from the switch which routes to the common ground location on the dash behind the LH AC vent. This ground provides the required negative signal for both switch and module BUT-with age there are several problem areas associated with the module being the capacitors and with the switch being the timer rheostat circuit. Bench testing will verify how well each works-and it can be a crapshoot.

gmachinz......looking at your kit I will still need linkage, so I will get that found and secured. pm me with pricing.

thanks for the info.

another question to toss out here-

I'm late model engine swapping my truck('76 GMC) and adding cruise control and what not.

My current thought is to use a later model column that has a stalk for cruise control and I guess wipers.

Does anyone know when cruise control came out?

So basically I'm looking at-
84+ wiper motor with fender mounted washer pump/tank
78-83 wiper motor linkage arm and nut
84+(or when cruise came out) wiper switch(column) and module.

I am assuming the 84+ still had a separate module for wipers?

What yall think?

are the later 78+ 2 speed AND intermittent linkage the same?

I found some linkage local but it's on a 2-speed truck.

You're refering the the parts in the cowl that connect the motor to the wiper posts right? That is the same on all 73-80s as far as I know. The difference is the motor, switch and delay box like pictured earlier.

You must use 78-up linkage arm-the motor stud on 73-77 trucks are not the same as 78-up.
