It is said that re-soldering fixes it, and I will see on my 91 diesel and dad's 92, but on my 91 gasser, I never noticed any broken connections anywhere, so I figured something was bad, like TD's relay, or some other aspect of the board, so I ended up going to the chevy dealer and getting a new one, installed it, and has worked perfectly since. I figured it could be the same situation with my 91 diesel, so I ordered one from the chevy dealer last time I was in.
Edit: just checked the part number and the receipt, and it appears I paid just short of 100 bucks for it, and its made in mexico. Shit. This may even warrant a return, sadly I didnt look at the receipt till now, I had a list of stuff I needed, but apparently I didnt check price on every item, and the total sounded fair, so I went with it. I am kinda pissed now. definitely check for bad solder before replacing, and even after the knowledge of this obscene price, I would still reluctantly go with the delco if your board is totally bad, as with most electronics, it just seems to last.
P.S. the exterior door handle made in canada was cheaper, and made in canada. that makes me feel alot better!
