I have already read a similar thread to this but I am looking for more info/insight.

I have a 2002 Jeep Wrangler 4.0. The blower motor only works on high.

It started out that "speed one" (for lack of a better term) did not work. Then 2 died. Then 3. Now we are left with only 4 working.

I understand it could be the resistor... or even the switches.

I have never worked on a blower motor of any kind and haven't even began to seek it out on this vehicle.

So, first, where is the blower motor located on this vehicle (to save me some searching time)?

Second, will the resistor and switches be obvious?

Lastly, is there an easy test to check what the problem is?

Any help will be appreciated. Thanks so much!
