I have a four cylinder and just today all of the mode buttons (5) stopped working and the other three buttons on that panel (Recirculation, A/C and rear defroster) also do not work. However, the fan control dial works.

I cannot find a fuse that controls those eight buttons. Is this something that I can fix with a fuse or relay?

Thank you,

Don

Don:

check to see if the system is vacuum operated. If it is, check for a vacuum hose. if you are lucky, with the engine running, you may hear a hissing noise.

I could not find information that the system was vacuum operated (not in the owner's manual) and I did not hear any hiss.

What else could it be?

Thank you,

Don, check under the dash to see if there are vacuum hoses running from the control panel to different areas on the HVAC.
