well that sucks i found a set for 50 bucks they look nicer in my opinion what would i need to do just swap the wireing
I did this. You just need:
Interior temp sensor (right of steering wheel, behind little grille)
Exterior temp sensor (kind of by the radiator on the passenger side)
Vacuum electric solenoid (little box w/ vacuum lines near the blower motor)
Solar sensor (little dome on the dash)
Both temp actuators (l and r sides of blower box)
Blower motor control module (same place as blower motor resistor)
Digital control unit (obv)
You need a wiring diagram for both systems. It's all a wiring mess that you need to connect, salvage as much wiring as you can from a donor car. You can tap into the existing harness for power, ignition, ground, illumination, a/c request, rear defrost, that might be it.
Unless you swap the entire huge blower box deal, you can only use one of the electric temp actuators (it is the same physical shape as the old one and just goes in the same place) thus you do not have the separate driver/passenger controls. Oh well. Be sure to wire up both anyway and leave the passenger one hanging somewhere so that the circuit isn't open. this will cause the little man icon to blink indicating an error code
