One of the three lights on the manual HVAC controls of our 2005 Sorento has gone out. I've found that 97309 3e000 is the part number for the bulbs on a 2004. Can anyone verify that that is the same part number for the 2005 model? More importantly, how do I get to the light??? I read one post that suggested there's a circuit board and soldering involved but I haven't determined if the whole control head needs to be removed or if the knob can be disassembled from the front. Has anyone actually replaced these bulbs? Thanks!
