- A viewer asked for some help with a problem that he is having with his wiper system. In this video, I walk through the basic troubleshooting procedures, including the factory service information on my 1985 Camaro. The basic system and troubleshooting routines should be similar for many of the 1980s cars. Since GM used common parts and systems across platforms, I expect that this wiper system may be common with other Chevrolet, Buick, Pontiac, Oldsmobile and Cadillac cars. Some of the processes in the manual advise to make jumpered power connections, so care is required to verify that those connections are correct. They may vary from model to model.

Very detailed video.one thing different in 1982 and 1983 is that there is no washer pump motor.The 82 and 83 washer pump connected to a cam that was run by the wiper motor and had to be assembled a specific way. A lot of the parts stores sell a replacement for these earlier washer pumps that do have a separate motor built into the earlier style of pump ,and do not use the cam on the wiper motor but operate independently.
Thank you for the information. I know that cam design was used for many years in the past, but not when they switched over.
Boy, that's a lot of pages for that system. Quite complicated. I'll just work on my differential instead!
Yes, some of these systems are more complex than you might think. A lot of engineering involved.
I have a 1985 Chevrolet Camaro Z-28. I did away with the automatic cruise control. I replaced all of the steering column switches: wiper switch, hazard warning switch, and the multifunction combination switch. I even changed the wiper motor. My wipers do not function properly. I can't use High, Low is High, Intermittent is Low, Mist is Park. When I use the jets, the wipers stop vertical.
I am so glad you brought this topic to the table because actually I've been having issues with the washer pump since long ago, when I install and activate the new one, it blow the motor, it start smelling burn and this is in a matter of seconds, I just hope the multifunction lever is not the problem....., Still I have bigger problems now! and I seek for your wisdom, I just found a coolant leak from one of the freeze plugs on the driver side of the engine and even though I know the solution is to pull the engine out of the car and replace the freeze plug, in all honesty I can't afford the cost right now because it is expensive, so what are my options with the engine in the car, a sealer maybe? I am well aware it would be a temporary measure, thanks in advance!
Well, as mentioned, one of the checks is for power feed and grounding. The problem with electric motors is that if they run slowly or stall out for any reason, current draw goes up and they quickly overheat. Low voltage due to poor supply or ground can cause this, or motor overload caused by a downstream restriction.
Regarding leaking core / freeze plug, it may depend somewhat on how bad it is leaking. I would try stop leak. I only have experience with the ginger root based tablets, because in GM we used them and tested our cooling systems with them. It would likely be most effective on small leaks, but worth a try.

I have not had to repair a core plug in the car, but I know some people do it. It is hard to drive a new one in if the working clearance is too tight, so it may take some strategizing. I don't know which plug is leaking, the front side ones are behind the mount bracket and that's more challenging.
