I have a 2003 Silverado Z71 Extended Cab, 5.3L Type T, 4WD. Some of the dashboard lights no longer work - for example one the dual climate zonesliders, the right one is out while the left one comes on with the rest of the lights. I've been told they are not replaceable bulbs but rather soldered LEDs. I have yet to start taking the dash apart. Can anyone confirm this is true or not and if they are LEDs, how difficult are they to replace? Would it just be easier to replace the entire boards themselves from a junkyard? Looking for any guidance to get started. Thanks.
