I try to use my wipers as little as possible because they don't quite work like they should. I've googled it to death and see a lot of similar problems but no solutions that don't involve a rabbit hole of replaced parts with no results. If I turn on intermittent they will stop halfway and stay there till I turn them off. If I use the washer fluid then they don't turn off for 10-20 minutes, sometimes they won't turn off till truck is keyed off. High/low work fine.
I'm leaning towards the multi switch on the column but wanted to solicit some wisdom from the org before I do a lot of potentially unnecessary work. I have seen recall for this in 2k's but nothing for e99's

most of the time its the mechanism inside the rotating switch on the column. I would just start with basics, check the fuse(s) related to wipers and washer pump, check relays if they are on the same wire, check the wires on everything. Usually just replacing the switch/column assembly works. Im heading that way myself. one a rare occasion I get my wipers not turning off until I rotate the switch back and fourth couple times etc.

verify the part is the same for yours but for my 1999 this is the part im most likely getting if it acts up one more time.

It may not be OEM but a few others had good luck with that particular dorman part. I had terrible luck with the dorman vacuum pump on my ac but that was the past. I actually have some Dorman parts on comutter cars for 7 years plus with no issues etc.

The switch is worn. Only replaced one set of motors. Rest were switches and wiring issues etc.

Thanks for the replies fellas! I'll put some due diligence in with checking associated relays wiring and such. Thanks for the part link! I'll post up on the fix so there will be more content for people to search with same problem.

There are three relays for the wipers. One of them is "Park/Run" and would be the one that would not allow the motor to stop. All three are in the under hood fuse box. Substitute the Park/Run relay with one of the others.

The relays are controlled by the GEM, which is on the back of the under dash fuse box. If there is corrosion on terminals and connections causing resistive connections, this would be a good place for it to crop up.

The stalk switch is an input to the GEM. Very low current circuit. Again, any corrosion on the GEM or under dash fuse box connections may affect operation.

never mind I got confused.

Gem 99-01
Vsm 02-03

I read the guy's post and responded with info for a 99.

I don't think the wipers are in the VSM in a VSM truck. I don't have a VSM, so I don't know or care. Neither does the OP in this thread. (It wouldn't surprise me if the wipers are in the cluster in a VSM truck. Many of the other GEM functions are.)

Dang! Plethora of knowledge here, I like learning. I appreciate everyone's info. I'll give it a good going through tomorrow and let y'all know what I come up with

So I started under the hood with relays and swapped 33 with 35, no change in operation. Looked behind fuse panel and found something interesting covering the 2 connection blocks


So I removed the fuse panel, 2 10 mm bolts, 2 10mm nuts for mounting and 2 10mm bolts holding fuse panel blocks (removed blocks first).



Removed two connectors on left side of panel/ module, remove top first then move panel to where you can reach the bottom one easier

This is what I found



For the fuse blocks I plan to gently clean the connections and very lightly apply dielectric grease with a small acid brush to the top half of the blades. The circuit board looked pretty good I think showing no dark/burned spots or corrosion. Will reinstall and moved on.
