2005 Acura TL w/Nav: I've changed all of my lights on the climate control buttons and none of them light up. The ones around the steering wheel were out too so, I changed them and those ALL work now. Anyone have a solution to this problem?

 

Were those standard bulbs or leds? Bulbs can be mounted in two ways, while leds only one way due to their polariy. However the probability you put all of them in wrong way is very low.

 

You will have to uninstall them and turn them 180 degrees, it has to be sitting in exactly right to have connection. I recently did my heated seats, trunk, VSA, shifter, dash (speedometer) and passenger airbag. Tried doing the Navi, but it's hard to get behind it without uninstalling the whole unit (Navi & Radio)!!
