Strange wiper activity on 2001 Suburban 1500

[Ntwrkguy1]

The wipers stopped working on my '01 Suburban. I pulled the fuse panel on the driver's side dash, and pulled the fuse for the wipers. It was fine, and when I put it back into the slot, the wipers started to work again.

 

Now I'm getting where the wipers will work sporadically, but all it takes is someone touching the fuse and they will start to work again. The fuse seems to be in there really tight, but for some reason, there must be some kind of connection issue. When the wipers are working, they are functioning the way they should, even on the intermittent setting. On sunny days, it's no big deal, but of course today it's raining and my wife wants to drive the Suburban to Virginia.

 

Any thoughts on this? I've even tried putting another brand of fuse in to see if that's the issue, but that didn't seem to have any effect.

touching the fuse ?, ,,,i hope you are good at electrical ,,,,you may have to get into behind the fuse block and see if the connector is tight to the fuse block

 

on the other hand the power from the fuse goes to the multifunction switch first and goes to the module ,,,,,check E and C into the module while the issue is happeneing to see if the multifunction switch is causing it ...

 

terminal B of the module is the fuse power to module ,,if its the only wire lit going into module during failure then the module is pooched ,,,,

 

,,,,good luck bud ,i hope the schematic helps abit

The schematic will help my mechanic, so thank you!

 

The part you mentioned about the connector being tight to the fuse block made me wonder, because there is a certain amount of give when I push against the fuse block. Maybe it's supposed to be like that, but it made me wonder.

 

For the moment, I've got about three coats of Aquapel on the windshield, so that will help get rid of the rain!

the fuse panel you see is all 1 pc ,there are maybe 3 connectors behind that screw into the fuse block,it moves because its clipped in ,ive seen them back out ,,,easy to diagnose ,,, good luck
