This item is a DIY automotive light bulb kit (contains bulbs only) for 2003-2006 GM radio unit part number 10359577 ONLY.
You will re-use your original blue bulb caps with this DIY climate control bulb kit. We have replacement caps for the radio light bulbs, however they will be a deeper blue than OEM and will not match if you do not replace all of them.
Basic instructions are included. Desoldering and soldering will be required. This is not plug and play.
