The cluster on my dash/center console that controls Air and Heat seems as though the right side bulb has gone out. At night, the right half is SUPER dim and can barely be visible as if it only getting light from the left bulb. How would I get in there to check/replace this bulb? Thanks in advance for the help!

There are 4 bulbs in the HVAC control panel. These are soldered in place. Take the radio bezel out by first removing trim from either side then 2 screws hold the unit in place. Disconnect connector and pull unit out. Remove center knob by pulling straight out. Unclip the 4 plastic clips that hold the front face. Remove plastic diffuser.All four bulbs will be very apparent. Just pull on the burnt bulb, it will detach from board. Solder new bulb in and re-assemble.

I just had to replace that bulb on mine this summer. I found a new bulb at radio shack. very easy fix. But it's really stupid how these are soldered in there.

If the pictures were still there!!!

Next time I change a bulb I will take step-by-step pictures for those who just want to change the bulbs.

OK doing a cluster this morning and changing a bunch of bulbs. Here goes with a few pictures of the procedure. These are the same bulbs as your HVAC.

Changing the bulb in the center of the picture to the right of the speedometer motor.
⇩


Firmly grab the bulb.
⇩


And tilt or push sideways
⇩


Then pull up, bulb leads will seperate from the circuit board without damage.
⇩


This will leave two traces in the solder islands on the circuit board
⇩


Refresh these islands with new solder
⇩


It should look like this once done.
⇩


Now take the bulb and socket.
⇩


Peel the leads away.
⇩


Seperate the two and discard the burnt bulb.
⇩


Take your new bulb
⇩


Insert in socket by spreading leads.
⇩


Trim excess on bulb leads
⇩


Fold over flush.
⇩


Tin leads. Not easy to do and take a picture at the same time with only two hands
⇩


Preheat and melt solder on first island then deposit bulb into place. Do the same for other side.
⇩


Apply power and verify that your work is flawless
⇩


Now you can do this on your own HVAC and not be scared.

Thought I'd get some kind of response from this how-to.... Ah well time well wasted.

Have patience old man coby. That is a great how to. I could have used that this past summer when mine went out but I had to figure it out myself lol. Not hard to do though. Like I said above I got my bulb at radio shack. Just curious where you found your bulbs? It took me a while to dig through all their drawers and find one.

I buy them 50 or 100 at a time on ebay but I use about 20 a week.

You're the last person I expected a compliment from, might be hope for you yet....

how long does it take you to do this coby? I'm normally in moncton once a year (atlantic nationals) and it would be nice to get red lights put in my cluster. I suck at soldering or I would do it myself.

Try a red sharpie first to see if you will like red.

8 bulbs probably 8 minutes.

I did the HVAC and cluster of a 2006 Sierra this morning and sold him a key FOB and programmed it for him in less than 45 minutes.
