Wiper Problem

Tonight it was raining so i had the wipers on and off. My wiper switch has always been weird since i got the car, the int. position is really touchy has to be a bit past the acutal setting and low worked okay and high didn't. And tonight i heard a pop and saw a flash down near my feet and i smelled a burnt plastic smell and my wipers stopped working. Anyone know what the problem might be ? I was thinking maybe a relay for them ? Oh i have a 93 HB DX. Thanks.

Hopefully that pop was a fuse blowing, doing it's job. The fuse probably popped due to a bad wiper switch. If your hazard lights are inop. also, then the control unit(relay) was the pop.
