Two issues with blower. Only blows ac or heat on high. Only blows out dash vents. Any help would be great.
Thanks

Did the OP say what model year TJ he has? That particular resistor is only for 2001 and older models.I agree, it sounds like your blower motor resister needs to be replaces.
Here's a replacement one:

So far as the air only coming through the dash vents, that could be caused by a vacuum leak or a bad flapper motor.
Be aware that what caused the first resistor pack to go bad can cause the replacement to go bad too. A common cause of blown resistor packs is the HVAC fan motor drawing excessive current from its windings starting to short out. The windings are bare wire covered in shellac and when that shellac starts breaking down from age or heat which causes the windings to start shorting together, excessive current draw through the resistor pack, wiring, and switch is the result.It was the resistor all is good now.
Yes. The resistor is receiving the full 12v and is dialing it back to the blower. That way you get reduced voltage to the blow at lower settings and full 12v at high setting.I think I have a related problem. The second speed on my blower does not work. First and second work fine. Is that a resistor problem as well? Thanks.

Ok. Is this the correct blower resister for a 2002 TJ SEYes, I deleted my original post. I didn't realize the blower motor resistor (assuming that's what it was) differed at all throughout the years!

This piece was loose and hanging under the ductwork. When I turn the dial the cable attached to this moved but of course this was not connected so nothing happens. I thought the end was broken off but not sure. It seems broken near the base of the longer piece that runs up into the air box. I have been unable to find a good exploded diagram of the duct system and components for a 2006. Not sure yet what I have to take apart to replace this, or exactly how it all works. Gonna keep searching before I purchase anything or take anything else apart. Has anyone else had this happen or had to replace this?
