Last night started the truck up and noticed the blower direction knob (the far right switch) light was not working, I assume its a led bulb can it be replaced or do i need to replace the whole switch?

The one on my H3T went out too about 2 months ago - dealer fixed it under warranty. They replaced the "control head" (GM part #25920831). Hope this helps.

Same thing happened to me and then it was out for months, out of the blue it turned back on and worked for a few days and went back out. I have been busy but when I have some free time I will look at time hopefully its just a bad connection or something simple.

If you need to, just buy the part online for the best price and I will walk you through on how to replace it. It truly is only a 5 minute job with basic tools to replace but the dealer will charge you a lot of $$$ on labor. I learned how to replace them from Alrock. let me know if you need my help. The hardest part and even that, is a piec of cake, is removing the center dash panel. f5moab just put up a great illustrated thread on how to remove the panel http://www.hummer4x4offroad.com/for...nter-trim-panel-(silver)-removal-installation (thanks f5). I can walk you through from there.

I do believe YOU can replace the LED or bulb, not sure exactly which light you are talking about. I have never had this control unit apart, so I believe the amber indicator in the knob is an LED, but the backlighting for the unit is comprised of small bulbs that can be found (usually) at a local radio shack.

If you are going to replace the entire control head, then you have nothing to lose by disassembling your existing one and trying to replace the bulb or the LED. It would require a small soldering iron and some steady hands.

I had a 2003 Vette where I replaced all the backlight bulbs with blue LEDs in the radio, AC control head, all the DIC switches and the door control, windows switches. The radio and control head came apart very easily and it was not that bad of a job, other than to get the LEDs to light evenly in place of actual incandescent bulbs (LEDs tend to be more directional).

It is the backlighting not the rear defogger light. And that was my feeling to about tearing into it just to see. Hope i dont start a fire!!!

You can tear it down and you will have to engineer a solution. There is not a plug and play replacement bulb to go into the socket. I could not find a replacement bulb though I did not look for too long.

Was it an led or reg bulb? Maybe replace the socket to?

It is a regular bulb. The Amber ones are LED. PM TheBroken as he did a bit of a writeup on this.

The OEM bulb is in a twist in socket assembly but that assembly is not available for purchase

Thanks Bigunit, This would be a better way to go and less messy, Ill take you up on the help if i go this route. I have experiance with the dash panel removal already so im alittle ahead of the game. But i do enjoy tearing into things. Ill let you know!
