DIY Climate Control Light Bulb Replacement
Posted 19 October 2011 - 09:41 PM
However, if your having a problem like me, then you will notice that some of your buttons may not light up anymore. This is due to fragile bulbs on the board.
While working on the board, I noticed more of the bulbs burning out just by handling/moving the board. Just to be sure there would be no problems down the road, I replaced all (9) bulbs with new ones. I recommend this.
12v bulb from Radio Shack Part# 272-1154
optional super glue
Follow the instructions on how to remove the climate control
Next I took out the (4) 3/16 bolts and removed the cover to access the top portion on the pcb or printed circuit board.
using a 12v source, you can apply voltage to any bulb and see which ones are out. Again, I replaced all of them.
Using a solder iron, heat the leads coming off the bulbs on the back side of the board and pull up. Be patient, takes some time to all (9)
Once removed, remove all the blue rubber covers and put aside. I used head light access covers to place all the parts so they wont get lost
Now you should have something that looks like this
Use the new bulbs from Radio Shack
Using the tip of the iron, re-heat the solder points from the back side while placing the bulb on the front side. Apply pressure and work back and forth from one terminal to the other. It will eventually slide right in. Then just go back and add tiny amount of new solder to make a solid connection
and dont forget the blue covers
The covers may be a bit loose, I used small dot of superglue at the base of the bulb before putting the rubber covers back onto the bulb
To ensure it works, you can apply 12v to any bulb and they should all light up again
total time to do board with parts already bought was an hour
total time to remove the climate control was about an hour
then to put it all back together, another hour
to play it safe, Id put aside 4 hours for this including part run

Headlight caps make excellent parts trays too...lol.

I just re-soldered the existing resistors and connections both in my gauge cluster and hvac unit.
Honestly the part that wasnt the hardest but most time consuming was removing the bulbs. You have to place the soldering iron on the existing solder till it liquifies at same time pulling the old bulb out.

Would you happen to still have them? If so would it be possible to upload them?
Thank you very much
