REMOVAL & INSTALLATION
On models with an air bag, wait at least 90 seconds from the time that the ignition switch is turned to the lock position and the battery is disconnected before performing any further work.
Disconnect the negative battery cable. Remove the control assembly.
Using a tool, remove the retainer and remove the blower speed control switch (except push-type, which is not serviceable) to the rear of the control assembly.
Installation is the reverse of the removal procedure. Connect the negative battery cable. Check operation of the system.
