climate control fan only works on high

[JOBO]

Hey All,
I searched for this subject but could not find it in this forum. Sorry if it's been covered before.
The ac/heater fan in my 2005 Wrangler only works on the highest setting. I'm guessing it is a relay or a fuse. How do I go about troubleshooting it?...I'm a newbie.
Please and thank you.

Its a resistor. Easy to access and change behind the glovebox

Hopefully that will fix it for you.
I used to have an XJ and the fan got where it would only work on high and then it got where it was slow to turn on. I lived with it for about a year and then replaced the fan motor to fix it.
