I had an intermittent short in my blower motor wiring that I finally resolved. Sometimes the blower would work, sometimes not, sometimes if I jiggled the throttle, the motor would come on. Often, when I moved the throttle, the blower motor would rev up or down. Turns out, the ground wire ran all the way to the throttle cable clamp just aft of the carburetor. That connection had become quite corroded and flaky. To fix it, I simply cut the ground wire and made a new connection to one of the instrument panel grounds. The new connection is about 18 inches versus a 10 foot run to the throttle clamp.
Q1: Why (this is a Catalina 30) did the blower ground run 10 feet to the throttle cable clamp, when a much shorter connection was available?
Q2: Is there a reason why I should NOT run the blower motor ground to the instrument panel?
