Dual Climate Control bulb problems
First post on here, but I am thoroughly on these forums every week trying to learn something new.
I recently embarked on changing out the incandescent bulbs behind the HVAC buttons after they all burned out. Thank you for everyone with instructions on how to do that.
They all work, problem is, they stay on all the time even with the car off! Which of course killed my battery after I noticed it... I work at an electronics manufacturing facility so one of our best solderers reflowed, cleaned, etc. and made sure all of my work was fine (and it was).
So, for now, I've removed all of the bulbs until I can figure out the problem. I've seen a few threads on the issue but many have just ended up replacing the unit (which doesn't come cheap...) so I wanted to see if someone had successfully resolved this issue?
Wiring issue? BCM? Relay somewhere? It would seem that a relay is stuck open all the time when it shouldn't be. Thanks ahead of time! If someone has a power board to sell, I may be interested if there is no true resolution.
