Alright dude, I need your help again. I dont know wtf gives.

I took the original head unit out because a bulb burnt out in there. I thought "maybe its replaceable"

nope. Put it back together, all went smooth. Suddenly the drivers side is stuck on full hot. Took it apart to see what I fucked up and put it back together- my "mode" and passanger's side is frozen too.

I cant change the mode or temp.
checked fuses
even replaced the HVAC control unit

Its stick on drivers side hot, pass side cold, full face vent. Blower control **** works. WTF gives here?

Are you referring to the HVAC module/ecu when you say control unit, or the head unit that has the burnt out bulb? My first guess would be the module/ecu is faulty, second would be the unit in the dash. If both of those are OK, there may be a faulty blend door actuator/motor.

I replaced the unit in the dash. What is the module/ecu? the body control module?
