I have a 93 Suburban with wiper issues. When I got it, the wipers would not work. It had sat for about 3 years. The fuse was good. I had power at the fuse block. I had power at the motor plug. Bought a new motor but still no wipers. So I checked ohms at the motor plug and had high ohms in the delay setting and the low setting so I assumed the multi function switch was bad. I replaced the switch and turn signal lever arm but still no wipers. Does anyone have any suggestions on something else I can check? Thanks for any replies.

I remember needing to change the module mounted on the firewall behind the distributor on our 93

Check/clean the ground connection (black wire)

Yep, that is what I had to do on my 93 Stepside....if I recall it was relatively cheap and easy...
