Electrical issues

1997 S10 4x4 ext cab ZR2 4.3 auto trans Having problems with the headlights and the wipers. Lights will not turn off with the daytime driving lights not disabled. (Fuse pulled) While driving lights go out in dash, also sometimes the headlights themselves go out. Turn them off then back on stay on a little while. Also when lights flash the 4x4 lights for high low flash on and off. Sometimes when it rains the wipers stop working in any mode, fast or slow, delayed or not. I know its alot to ask in one thread but have you seen this before? Is the lighting problem connected to the on/off/daytime module? I have the number 15 drl/fog fuse pulled already. If I leave it in the lights wont go off when turned off. Hope you can help, I've tried to be as clear as possible.
