THE BLOWER WILL ONLY WORK ON HIGH
It was on a different car (an old Vauxhall) but I had that problem. The resistor on the back of the dial had blown - so the only setting that still worked was the one that didn't need the resistor (i.e. the full power option). My car was probably a bit older than yours so I don't know whether things are still that simple!

you need to replace the blower risistor. it should be located very close to the blower motor. it usually has 3 wires that are in a row and one wire a little to the left of it but located on the same oval fixture. go to the auto parts place and buy one . this way you will no exactly what it looks like so you do not have to spend a lot of time and money researching it.

Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

Your intake air temperature sensor is part of the MAF (mass airflow sensor) and located right off the air filter housing in the large tube going to the throttle body.Its held on with 2 screws and has a 5 wire electrical plug going to it.

I have the same problem with my scion xa 2004. My fan only work on high and sometimes it does not even work on high. Can someone please help me with changing it. I do not even know where is the blower motor in my car and how to take it out.
