Thanks for your answer, but where is this located? You say in heater box, Meaning? Where the motor is? Or back behind the switch panel? And can it be checked with a ohm meter before I go buy one?

Ok I replaced the part and its fixed thanks!
If others whant to know where this resistor is see below.
How do you replace a blower motor resistor in a 2003 jeep Liberty?
Open your glove box and empty it out. There will be two supports on each side of the glove box, push these towards each other and the glovebox will kind of " fall out.&Quot; It will still be hinged but hanging down far. You will then see a 5 wire connector going to a mount with two screws. Unscrew both of these with a nut driver, the whole thing will pull out. It is a creditcard sized resistor board. Unplug the cable from the resistor. This is what you need to replace to make it work correctly with 1 2 and 3.
