Electrical issue on my 95 K1500

[YE9Longhorn30]

So I was on an almost 300 mile round trip this last week and all of a sudden i lost my wipers (there was spotty showers all the way there and back)and my blower (as in the speed control) will not respond other than some buzzing noises here and there(so it is very tempermental). I pulled the dash apart and i cannot find anything disconnected or shorted out. Are these two connected somehow and i just cant see it? Or is it possible they just croaked at the same time? Any help is much appreciated !!
i have checked all the grounds, cleaned them up and reattached them. Even put a new one on from the firewall to the frame
