Steps
Prepare the dash
Disconnect the negative battery cable and wait as directed by the service manual before working near dash wiring. Remove the audio unit using the correct release method for its installation and unplug its connectors.
Remove the center trim
Remove the four fasteners in the audio opening and carefully release the trim panel. Remove the ashtray, unplug the hazard switch and power outlet, and label each connector or cable before detaching it.
Disconnect the selector assembly
Release the mode, temperature, and fan-control connections without bending their clips. Under the driver-side dash, unclip the actuator end and separate the selector wiring and cable assembly from its retainers.
Transfer the selector controls
Remove the selector knob and housing from the old assembly, then fit them to the replacement in the same orientation. Route the actuator end through the dash opening and secure it in its original retainers.
Reconnect and test controls
Reconnect the selector, temperature, fan, outlet, and hazard connections, then refit the trim and audio unit. Reconnect the battery and verify that the mode doors, fan speeds, temperature control, and hazard lamps work.
Check your vehicle’s repair manual for exact specifications and fit.
