| Mopar Blower Motor Resistor Block |
So yesterday I got into my 2004 Wrangler and the fan wouldn't work correctly. The fan would only work on high, but the other 3 settings wouldn't work whatsoever. I ended up Googling the issue. When the blower only works on high, it means that the resistor block has gone bad. Since the resistor is only used for the lower setting and the high setting is full on, it is the only setting that will work since the resistor block isn't being used. I don't know if you have ever driven with the fan on high in your Wrangler, but it is extremely loud and distracting. It is an easy fix though.
