I have to assume that comment was directed at me, since evildky didn't mention anything about it.
You are correct. The temp sensor only reads out on the auto climate control display.

Since he has a 1986 model, it's easier to ask if he's got a digital dash than automatic climate control. For the 1984 to 1986 models, the Digital package included the auto climate control and digital cluster together. Once they got to 1987, the digital dash was an option for the GLL models (those got the auto climate control).
