Having problems with your 2002 Jeep Liberty ?

Ok I have a 2002 Jeep Liberty with the same symptoms as most people regarding the fan speed only working on 4...however, yesterday now not working on that speed either, so no heat at all....I have checked fuse #24, it looks fine, but I will replace later this evening, I have replaced the Control Unit as well as the Blower resistor and I still have nothing, by process of elimination I assume that the Blower Motor is the last thing?

Hi it is uncommon but does happen , that the blower motor jams. the best way to find out is to take the power leads that go to the heater motor and bypass them directly to a 12v supply. if it runs, thats a big headache out of the way.. the only other thing then is the dash switching itself. youve changed the rheostat under glove box i take it.. so its either power or controlled power or the unit itself..
