My memory on this isn't so good but here goes: I have owned my 1996 Tahoe since new. In the late 90's or so, there was a "recall" or service bulletin that called for the replacement of a wiper controlling computer board or chip. I think there are some free services that will allow you to put in your VIN and find all the service bulletins for the car. My wipers failed and this was the solution. They have been working fine ever since.
BTW, the under hood retractable light is terrific ... used mine just 2 nights ago ... feeding fuel in to the TBI (see my other posts).
