I have tried 3 different hvac units,all of them are reading in celcius instead of farenheit. Any ideas how to fix this?

us regal owners just hit the E/M button it changes everything to standard or metric.

GM Service Information doesn't have an owners manual for a car this old - but the ENG/MET button on the DIC also changes the HUD display.

I suspect it also changes the display on automatic HVAC control units.
 


I have a 98 gtp with digital hvac, eng/metric doesnt change it.Is it possible there are different hvac controls for Canadian cars that are only programmed for Celsius?

I only see one control unit listed. It's discontinued.
 
Got the issue resolved, put unit out of dash, and unhooked the single black wire that has its own single connector..back to reading F*
