converter locking problem?

[Asfalto]

Hi everyone! I need your opinions for this issue on my 1998 tahoe 5,7 4wd 4dr.
description: at highway speed, using the intermittent wippers, almost at every wip the transmission converter unlocks and suddenly locks again with the consequence of continuos rpm change. Many times also the cruise control disengages.
When I park the car I smell i sligth smell of clutch burnt.
No codes!

What can it be?

I would check the wiring around the steering column going to the turn signal unit.
May be a faulty turn signal switch too.
The turn signal switch is an all in one unit which is why I'm referring to it.

thanks, I'll check asap.
more notes:
- it happens either in the temporized wipper or single wip
- same behavior with the cruise off
- it started acting like this after I drove on a flash flooded road

Flash flooded road meaning the water was really high and you drove through it and if so how high and if so and was high water why did you do that? Check for rubbed thru wire insulation in the same area that Jerky Arm Ape talked about but I still gotta know if you drove thru high water and how high up was it?

no big thing! it was just 12 inches of water; down some pics.
So you assume that water entered the vehicle and reached the wires of the stearing column?

The problem seems self-fixed.
I only had a visual inspection under the steering column and a check of the brake switch.
I also charged the battery..
