Before installing the new heater control, begin by taking off the center bezel of the instrument panel and removing the wire plugs from the cigar lighter,
Power Window Switch and rear window defogger switch. After that, lift the knee blockers on both the right and left side. Insert a firm wire or tool into the bottom hole of the headlamp, push up while pulling rearward gently and release the lock tab without damaging it. Take off the steering column shroud which could be assisted by lowering the steering wheel slightly. From there, take out the instrument panel bezel, again making sure not to damage the locking tab and remove the screws from the control assembly using a firm grip. Now pull the assembly back and remove any wire connectors, lines and cables before unplugging the switch. For uninstallation, use the steps mentioned again in reverse.
