Window Wipers Problem

madmaxwell87 · #1 10-07-2009, 09:16 PM

So my truck has been having the wipers stay on even when the switch is in the off position. So I read up on here and pulled apart the switch, cleaned and re-greased it and they still stay on. So i looked at the fuse for the wipers-fine. The only other option is the start/park relay under the hood(#202). I couldn't get it out however. Does this sound right? am I missing anything? and am I just not pulling hard enough on the relay?

No problem, just message me if you want it moved, but I think the elctrical is where it belongs. Maybe someone will chime in.

I would say the MFS is the problem still.

Ghost wipers is usually caused by the MFS making contact while in the off position.

Remove the MFS from the steering wheel column, and test it

Don't know how I missed this one the 1st time around

No problem, you found it now. So you think its still the switch? The wipers will go faster when pushed to the top two fastest speeds but wont speed up or slow down in the intermittent stages. They wont start on their own, just wont stop when turned on.

Looks like I need a volt meter or test light. So I should just test terminal 4 and 6? Are these schematics of the board you can see when you pull the spring and plastic piece? Thanks for the help

Edit- I did some research on the MFS-I guess ill pull the end of the stalk off again and clean/re-lube it. Looks like I might need to pull the whole thing out and check the connections though

The diagrams above are the connector in the steering wheel column, where the MFS is at.

Here is a thread that shows the MFS removed, you can get an idea of where they pins are at.

You will need a Meter that can measure resistance to test the switch, test light will not work for this.

From the description, it still sounds like a problem with the MFS. Once you run the tests, you will get a better idea
