Can't Change Climate Control Settings

My climate control is stuck on the def/floor setting. I don't mean that I have sticky buttons, all of my buttons work but pushing a button doesn't change the setting.

 

While my backlights have been out for awhile, the little green light under each button has alwasy worked until about a week ago when I noticed that it too went out. I can't say for sure if the climate controls stopped working at that same time but it is entirely possible.

 

Anyone know which fuse these are on? Are they electrical switches or vacuum switches?

 

Ideas please..

 

Thanks!

This is an electrical unit. This is a good time to replace the bulbs as the unit is going to have to come out. Its possible that this is as simple as a loose electrical connector on the back of the control panel. It happens.

Cool, thanks Nipper. Are they switches or am I going to find a printed circuit back there? If it's a circuit board then I guess the only way to test is to replace with a known good unit eh?

 

Thanks again!

PCB, they are easy to take apart to change the bulbs, disconnect the cable from the Passenger side heater control, much easier than pulling the cable out of the unit.

 

Search the board for lots of good info on replacing the bulbs.

 

If you need a good replacement let me know I have several spares.
