I had 3 lights not working. One above the Air Circ, A/C, and Feet. I thought I'd take this apart and replace some bulbs but i found out they were not typical bulbs.

What I did was dust off the soldering gun and just touched the tip against the two pins behind the light that was not working. I added a barely noticeable amount of solder to each pin. To do this you must disassemble the HVAC to the point where you have the circuit board with the buttons attached in your hand. Not sure if this has been covered before but I hope this helps some people out. Probably took me 1.5H start to finish figure it out as I went. If your **** like myself and want those lights to work try this method.

 

Yep, cold/bad solder joints in the logicon are a fairly common issue. Covered in the FAQ, actually.

 

Ok great. Just wanted to share my experience. I know there is a ton of info on this board and I wasn't sure if this was ever covered.
Thanks
