The blower fan on my 2003 focus was only working on the highest setting, so I set out to replace the resistor. I plugged into the new unit and checked. The lower speeds now worked but within seconds, the resistor unit was extremely hot./And it burned my fingers. I checked the the part number and it was correct. Then tried another resistor and had the same results. Both of these resistors were new. Any ideas? Thanks
have the same problem?

THAT'S HOW THEY LOWER VOLTAGE
THE RESISTANCE IN THE WIRES MAKE'S 'EM GET HOT
IN MANY CASES, THE RESISTOR IS INSTALLED IN A DUCT SO THAT THE PASSING AIR WILL COOL 'EM OFF
MAKE ANY SENSE?

Make sure the blower motor isn't drawing too many amps. That is a common cause of the resister going bad in the first place.
