My 2009 window switch driver side fractured off. Anyone replace just the button possibly? Do I have to remove the entire switch? Do they sell just the button somewhere?

 

I have an 06 and the lights in the two front window switches are out. I asked the local dealer about it and they said those things come assembled as a complete unit. So no replacing any individual pieces. I would say try some junkyards to see if you can find one or maybe eBay.

 

You can change out the bad bulbs in the driver side door window switch.
Just gently pry up the entire switch assembly and unplug harness. Remove (untwist) the bulbs and remove blue cover from bulb and put blue cover on new bulb, reassemble
You can the exact bulb and base here,

Unless you can find a junk yard switch assembly, no you can't get just change out the one button.
You will need to replace the entire assembly. Check model year before ordering

DocOlds turned me onto these exploded view schematics

 

THAT'S AWESOME!!! However, that link goes to a seller that is "on vacation til Dec 31, 2015 and not processing orders"... I'm gonna see if I can find others.

 

Check my latest PM, I found a guy in the county [sic]

 

Not sure but if you end up needing one let me know Hummer H3 Window Switch

 

Thanks I worked it out and bought a pass side and swapped the pull up/down switch....cheaper.... but a still a damn expensive just for the once little pc.
