1990 New Yorker climate control only displays celsius
 

This isn't a huge issue by any means, but it is a bit of an annoyance. When I bought my car last month, the units were in fahrenheit and all was good, but somewhere along the way things switched over and now I can only get the control unit to display celsius units.

I read on certain pages that there's a switch for it on the back of the control unit, so I pulled that earlier today and found there is no physical switch, so I assume it has to be a combination of button presses on the main unit. Any help would be greatly appreciated!

Same thing just happened to me, so far I can find no fix. If the body control module switched it, we are screwed, they are no longer available.

If you find a fix, let me know please. While it is still working properly, seeing 28 instead of 85 is messing with my head.
