If you are talking roadmaster, there is a pin/wire to ground behind the climate control head. I will have to dig it up for you.

Looks like they took the button off the newer models, on my older climate control module, there is a dedicated button to switch.

yeah you have to ground a pin on the back of the unit. Ground pin D7 on the HVAC control and it will be in Celcius all the time. Or there maybe a wire that is run to connector C220 pin B and you can ground it there. Not sure where this connector is as I can't find the reference, but typically if the car was equipped with Daytime Running Lights, it would have this pin grounded, hope this helps.
