Disconnect negative terminal from battery. Pry the plastic trim that goes around the radio and the three HVAC control knobs (Blower, Temperature Control and A/C-Heat Select.) Remove the knob from the stem of the temperature control switch. Four screws hold this assembly to the dash framework - remove using 7mm socket on the two top screws and a small 7mm open or closed end wrench (a 9/32" will also work.) Once the 4 screws are removed there is enough of room to unplug the 3 wire cable to the temperature control switch. Remove the one screw with the open or closed end 7mm wrench. The switch can now be removed from the assembly.
