Question Defrost wont shut off....?

I have an 02 Tj that only has defrost. I have tried moving the knob thru all the other setting and moved the temp knob too but to no avale. It will change the temp of the heat but it will not move off of defrost. Also i have no controls for the volume of the air coming out. It either is on full blast or nothing. The low or medium setting do not work! Could this all be one problem or is it just a bunch of little ones? Thanks in advance for all the help!

Sounds like multiple problems--one problem is in the switch on the far right. Mine had that problem when I bought it. Not sure what service did to fix it, but their initial guess was that the flapper was messed up that switches between the settings.

The blower speed problem is most likely your blower resistor...common problem.
