Delay wipers don't work
 

On my 85 the delay wipers don't work. I have tried three different modules. I was told they were good, but don't have another vehicle to test them on. I tested the resistance of the delay switch and have a range of 50 to 500 K Ohms which is were it should be according to my research.

Does anyone have a wiring diagram for the wipers or any ideas where the problem may be?

The only ones I have ever seen were fixed by replacing the module. Are you sure that the motor itself is ok?

It works in both low and high speeds and the mist function works, just not delay.
I believe the wipers run in low speed when on the delay, I'm wondering if the switch is not powering the low speed circuit when the delay is on. I need to search for a wiring diagram.

Anyone else run into this?

My 85 is the same i replaced the module no difference haven't whent much futher yet. Low and High work fine so do the mist and washer.

I attached the 1989 R/V square body pulse wiper schematic. I can't guarantee the colors are the same from 1984-1991.
I don't have a schematic for the pulse module itself.

Hatzie,

That diagram is what I was looking for. Now I just need to find a little time to troubleshoot the system.

Thanks
