Morning all:

87 waggy (inline 6) wipers are not working at all. No motor sounds or anything, so I'm guessing it is electrical. What fuses/relays are applicable? Where are they located? Is there a way to test the fuses or relays to see if they work before I replace?

Thanks in advance!

The cruise control is not working, nor is the window washer fluid pump. Is there a component that all three of these things are routed through?

I have intermittent wipers on the column, so there should be a module, but I'm not seeing it. Any thoughts on where it should be or what it looks like?

Thanks!

 

The wiper module should be velcroed the back of the knee plate directly under the steering column.

Get your self a:

Fuse tester


Holy hell! That's a big fuse tester!

 

Morning all.

I do not believe it is the circuit breaker. The multi-meter shows that the circuit breaker is closed when it is out of the fuse block.

Is there a switch or connection that would effect both the wiper motor and the washer motor?

Thanks!

check the ground for that circuit.

 

Is there a central ground connection? And if so, where would it be located?

 

Are you getting voltage thru the circuit?

You need to check for voltage.

Could be the multi-function switch.

 

I have not checked that. Would I use a multi-meter the on the actual circuit in the fuse box the same way I check for continuity on the circuit breaker?

Where is the switch to which you are referring? Is there a way to check that as well?

 

You'll want to find the wire that supplies 12volts to the wiper motor. First check to see if it's getting power. If it's not working then it's probably not getting power (Wild guess).

The multi-function switch is the stalk on the column that controls the wipers. Pull the column apart and test the wires in that switch that power the wiper motor.

 

I just went online to see how to replace the multi-function switch and it looks to be beyond my skill level.

Am I reading things correctly? Do I have to remove the entire steering wheel to do this, or is that not necessary? Tips or better yet, step by step would be greatly appreciated!

My Waggy has cruise, intermittent wipers, and tilt.

 

No, I didn't mean for you to remove it. I meant for you to pull the plastic covers from the column and dash kick panel to gain access to the wiring harness.

From there, with a circuit wiring diagram, you should be able to trace the power flow of the circuit and locate the issue.

 

There is no plastic cover on the steering column on a 84-94, it has a GM sourced column.

 

Ah, 87. That's true.


Tho, I can remove the covers from my 93 just fine.

Regardless, he can still access the harness he needs from the underside of the dash.

 

This is an 88 Column and the plastic comes off.

 

The wiper motor and the washer pump share something common: The intermittent wiper control module.
