Changing the AC from Fahrenheit to Celsius

[ReGet]

Today i tryed to change AC in my 1994 MTX from Fahrenheit to Celsius.
I grounded red wire (20 pin), but nothing happens
What is the problem? What should i do?

I thought it was as simple as pressing max A/C and the front defrost button at the same time. That works on my '97.

On the V6 cars, there is a lead with a ring terminal on it under the dash (usually just hanging somewhere left of the radio) that needs to be grounded to change the EATC to celcius. There are a couple of screws in the area of the lead that you can attach it to.

Any body find out how to change from Celsius to Fahrenheit on a 90 MTX?

The answer would be in the post right above yours...that was written 8 years ago.

Actually Chris posted the answer on how to change the temperature reading to Celcius. To change it back to Farhenheit simply unground the ring terminal

Holy old thread Batman!
