1998 Voyager recirc AC switch LED not working
 

I am in Australia and have a 1998 Voyager. To start with none of the LED on the centre panel would work. I have run the calibration tests and now most of the LEDs work when the switches are operated except for the AC and RECIRC switches. When the AC or the RECIRC switch is operated the LED in NOT illuminated. Can this be an LED failure in both switches, or are there other tests I can run to "reset" these LEDs?

Any help would be appreciated
