For some time now the six buttons where the defroster a/c and so on are have been flashing. What can be causing this? Is it something I can repair?

 

With key on engine off, Set blower motor on high, Open all a/c outlets (vents), depress the a/c and wash button at the same time, after 5 seconds all lites will flash. Let it flash until it stops flashing the LED lites.

 

Master tech, what were the flashing lights indicating?

 

The control head has failed, battery has been replace or dead battery.

 

Master tech,

Thanks for the info. I did what you suggested and now the recirculate and a/c buttons flash. How do or when do they turn off?

 

When flash slow down to one blink and stops blinking for a second then turn the key off.

 

About how long does that last? A few minutes or longer?
