I know I'm Not getting any power to the switch so what would cause this seeing as though the fuse is good?!?!?! Oh and I tested the switch just in case and its fine!!

Sounds like the resistor, it's only a $13 part.

The resistor is good!!! I know this because I put it in my buddy's Jeep and it allowed him to run all 4 settings on his!!!! Do people seriously not read a thread before they post the same thing 15 other people have??? I know this isn't my thread but c'mon people if u would read the whole thread u would c that I've been through the resistor and the switch and the fuses and still HAVE NO POWER TO THE SWITCH...... If the switch has no power then the resistor is not going to matter!!!

Ah, nm see you said high is now dead also, three people asking questions on the same thread makes it a bit confusing, no reason to be an *** about it.

Since you know the blower, resistor, and switch work and fuses are good that only leaves the wiring.

I'm not trying to b n *** and there's only 2 people asking questions on here, me and the OP, and the op solved his problem with the resistor so that leaves me!! But back to the question..... is there a relay between the fuse and the switch?? Cause I've been told there is a relay somewhere behind the glovebox but can't find the dang thing and the wires don't look burnt at all.... the connector on the back of the switch was melted a lil bit but not to the point where it was bad but I fixed it anyway

Just a fuse for the blower motor. I had the same problem and it ended up being the blower motor itself. I would replace it, its only 20 sumthing bucks.
