how to replace the blower control switch
What’s the nature of the problem?
If you’re having problems with the blower control, on these GM trucks the problem is almost always the blower resistor pack . . . and often the pigtail, as well.
In any case, I believe you can’t get the blower control switch separate from the ac control head
Is this the overhead switch for aux blower motor? If so, remove the console from the headliner, then free the switch from the console by releasing the rear tabs.
