Question about 1997 Chevrolet Tahoe
Could be your Body Control Module (BCM) has gone bonkers. GM geniuses decided their vehicles needed more computers on board. Most of your dash and interior switches and controls are routed through the BCM, a small mini-computer. Later models require reprogramming of these modules to the main computer. Not sure about your '97, you better check. Lights, wipers, turns-they all go to the BCM, before the wires go to the actual motors or bulbs. Not friendly territory for DIY'ers.

Check the fuses under the hood...chances are it's one of them....there's not much left to check after that....check the fuses inside the car as well...it might be the high beam switch is bad that switches the low beams to high beams inside the car.

chances are! these are very problimatic and gm had an updated module for these wipers. i say that not knowing though if ANY aftermarket items such as radios, alarms, etc. have been installed and tapped into the harness coming from the steering column. think back to when it started(or at least noticed) and make sure this wasnt "professional" error. this happens alot and if caught ive personally seen a radio shop cut a $2100.00 check for repairs i had to make. cheers.

There's a wiring connector located below the battery box, you can see it better from under the car. Check to see if any of the wires coming out of the connector are green from corrison, if so carefully splice in new wire(s) to repair, this is caused from the drippage from the battery tray.

SOURCE: I have a 1983 Chevy
take a look at the dash ground wire located next to the right of ebrake release handle. if the bole holding the ground wire is loose, which was quite common it will cause all kinds of feed back problems, like described in the comments section to your question.
