03 Tj heat ac control unit

Recently the settings on the unit have not been working. I can only get heat when I have the setting on the highest one, the fourth. On settings one and two, no heat comes out. And on setting three there is a very small amount, maybe like a typical "setting one". Does anyone have a suggestion as to how to fix this or do I just need a new part like the one below?
I also only have heat blowing from the front vents. No access to the defroster or any other settings. Any ideas?
