does anyone know if i can take out my ac/heat control box and put in one from a 4th gen? i got one free, but i dont know if itll work right. The one in my 92 RS is pretty messed up its got a broken slider and the **** slips, anyone help?

 

i really don't think it will work. im pretty sure everything is way differnt and wont fit into the dash. not to mention that i think all the door controls are electric. but they might still use vacuum for the doors.. but no it wont fit without a lot of modification..

 

just get another HVAC Climate control unit from the boneyard. you'd be better off. make sure the cable that controls the blend doors for hot/cold are properly adjusted and is actually connected.
