My 85 van started blowing the fuse for the front wipers a few days ago. I drove the van from NY to NC, ordered a replacement motor. It seems that the fuse blows at random, not when the wipers are in use. I removed the instrument cluster and steering column covers to examine the wiring as best I could. I don't have wiring diagrams with me here. What I am wondering, is the motor energized, and switch completes the circuit to ground? If that is so, could an internal short in the motor be causing the issue? I have other outstanding electrical issues with the van. The fuel gauge and temp gauge are both inop. I know these are fairly common issues with the vans. Thanks for any insight.
