No heat at all :(

I have a 2000 Jeep Wrangler. I have checked the fuses, changed the resistor and the blower motor, and still nothing is blowing out on all for settings. I am wondering if I have a short somewhere or if I just change out the blower motor control switch. Do I also need to change the control unit or just the switch? And if I do have a bad connection or short somewhere, is there a way to trace it? Any suggestions would be greatly appreciated, as I live in Ohio and its a bit chilly right now.

The switch can easily be the issue. I recently replaced mine...I had low speed but nothing else. Like you I'm in Ohio so this had to be addressed sooner than later. Mine got hot at one the and melted one of the tabs away. Did yours suddenly not work on any speeds or did you lose them at different times? The high speed should work regardless of the resistor pack...that's how I knew my switch was bad

Todd-
All of them went out at the same time, thats why I am so confused. I thought I should have at least the high speed working, but nothing on all four. What is the chances of it being a short? How hard was it to get to your switch? Changing the resistor and the blower motor was actually pretty simple.

Might be the switch. It can be tested...I saw a write up on the jeep forum but I suspect that if it is the switch it probably got hot.

Use something like a plastic scraper and pop the trim piece on the top of the dash. You can get at the two screws that hold the top portion of the center cover...don't remove just yet. Then pull the ash tray. Remove the screw behind it. Gently pry up on the center console cover and pull it away. Now you can get at the controls. Remove the 4 screws. Verify that all the connections are snug before pulling switches. If the switch connector looks melted you probably have a switch issue. You'll need to pull all 3 knobs and the face of the box in order to get the switch out. You'll see why when you're in there. Btw you may want to disconnect ground first! I got mine back together and nothing?? Then I noticed that the connector on the other end of the box had become disconnected. Pushed it down and voila!
