Wiper Fuses Keep Blowing

I have a 1994 Chevrolet Silverado C1500, 197,000+ miles. Recently my husband replaced the control for the turn signals in the steering column. Before we replaced this part, my wipers were working fine, the only thing that didn't work was the left turn signal. Once we got in there it was the "spring" on the left side that controls the left turn signal that was broken. After he put everything back together, I noticed my wipers quit working. I checked the fuse panel and found that the fuse was blown, so I replaced it. They worked one day and I went to use them again today, and no wipers, the fuse is blown again. Prior to us working on the steering column and the turn signals, there was another fuse that was not only blown but almost melted in half, if was for the dash lights. This fuse was also replaced. Is there a possibility it could be an electrical problem that is causing these fuses to keep blowing? ?
