1989 Chevy S-10 pickup wiper/cruise control problems Sign In

I have a 1989 Chevrolet S-10 Tahoe pickup, 4.3 v6, and I am having problems with the wiper control, and cruise control. This truck has the cruise/wiper/turn signal combo on the column mount control arm.The wipers will not shut off. They are coming on every 45 seconds or so, and the wiper control switch will not shut them off, when you turn the control arm (switch) you either get full speed, or the 45 sec intermittent speed (there does not appear to be any other setting contacts being made). I have to pull the fuse to stop them.

The cruise control does not function at all. The turn signals, and headlight dimmer/bright works.

I bought this truck even though it has this problem but I have never worked on these systems. I have purchased a new control (cruise/wiper switch control assembly), and a turn signal switch assembly. Am I on the right track?

No, I doubt you are on the right track. There should be a replaceable pulse circuit board on the motor that is responsible for parking and pulse control.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Thanks for the great info. I looked for a pulse circuit board online, found one for $22.00 and have it on order. I have been frustrated with this, and after researching this site, and receiving your reply, I am starting to feel better about solving this problem. Thanks again Hammer Time.
