I havea 2000 Pontiac Grand prix GT. I'm having problems with two things with my a/c, first thing is that there is a digital display and it reads a number with the letters EXT next to it, I would like to better understand this number because when it reads 37 or less my a/c stops blowing cold air, and when I drive the car the number quickly falls to the number 37. Please help me better understand, and help solve the issue with my a/c. Thank you in advance.
have the same problem?
