Just replaced the blower motor resistor on my 2000 jeep cherokee after the blower only worked on the fourth speed. Up to a couple days ago it stopped working so i put a new blower motor resistor on today after everyone said that would fix the blower speed problem. Well, that didn't do anything. What could the problem be now? Thanks!

Mine does the same thing too.. Only works on 3 and 4..
They're both the same speed too..
Would be great to see what you find out. I haven't gotten that far yet.

I heard that when blower motors get old and start to crap out they just work on the higher settings, not sure if this is true or not.

Where are the Blower resistors located. I replace the relay and the blower still works on high only.

other possible area for trouble is the dash switch oldr xj will burn them up causing this issue

I submitted a "How to replace your blower motor WITHOUT removing your accumulator or refrigerant" incase it actually IS the motor. I don't think any of the mods approved it yet. Let me know if you want it.

If the blower motor only works on high it is most likely the resistor. if it doesnt work at all it is probably the motor, or the wiring. On the highest setting the motor does not use the resistor, thats y even if the resistor is bad, the highest setting will still work fine.
