hello, i recently noticed the heater blower switch under the dash gets hot after turning on the blower and I even saw sparks at the base of connection. I am assuming I have to repalce the harness switch all together? I found out about this after noticing a faint cable burning odor while air was on. i wonder if this was a factory problem?

The component that you may be looking at is the blower motor resistor and they do wear out. They are easily purchased and don't really cost much.
I have purchased a 92 ford tempo. The relay behind the glove box has gotten hot enough to melt connector slightly, the blower motor has been hot wired to battery, and I want to repair heater as it...
