Blower motor won't run
2010 Liberty. Just wouldn't turn on. Took out resistor controller behind glove box, has 5 aluminum fin heat sink about 4" in length. The connector is one single heavy gauge blue and one 3 wire combo, heavy gauge blue (like single wire)/small blue/ heavy gauge black. Heat sink gets hot and fan will not run at any speed, full on or not. Motor or relay/resistor bank, or both? Can i jumper to the blower to see if it works??? Thanks!
