Check the listing for details. GM Climate Control Bulb to Blue LED DIY Upgrade Kit 03 04 05 06 Silverado Tahoe. Color: Blue, Condition: New. Listed at 18.99 USD. Climate Control DIY Repair Kit with Blue LEDs. The kit comes with all of the blue LEDs you need to update the lighting in your climate control, detailed instructions with pictures and tech support if you need help. Kit is compatible with both manual (up & down slider) climate controls and also digital climate controls. The Climate Control Module is not included. The main picture is for display only. Our LEDs were specifically designed for GM Climate Controls and do not require a resistor as they are built-in. Our LEDs are high quality 12-14 volt LEDs, not the ones that require a resistor and tedious soldering. The LEDs will dim up and down just like normal bulbs. The cube-shaped LED emits light 360° in every direction and provide even light distribution. It's simple to solder these surface-mount devices to the circuit board in your climate control once it's removed from the vehicle. You will need to desolder your stock incandescent bulbs and solder these on the circuit board. Install time is about 1 hour. The slider knobs on 2003 - 07 manual climate control units can be pressed on from the factory. If you need to take the unit apart to replace burned out bulbs, the knobs first have to be removed which can damage the slider control and circuit board when trying to pry the old knobs off. Don't risk breaking the unit when you can just cut the knobs off and replace them with new ones after the repair.
