How does one read the codes on this Sedan DeVille? I know it has something to do with holding the "Range" and "Reset" buttons or some such, but can't remember exactly what.
AND it is not in the owner's manual.
Does anyone have that procedure?
Thanks.

You still da man. I knew it was something like that, but I could not remember the sequence.
Now, I'm off to count first and second blinks.
Thanks much.

You don't have to count any blinks. It displays the codes.

I'm glad you sent the additional info. I ran the procedure and got nothing but dashes. So now I know that the outside air temp sensor or the circuit is bad.
Can you tell me where THAT sensor is?
I also just learned that there are two motor mounts broken. The car has very little power until it hits about 45 MPH, then it seems to be a little better. But until I see the codes, I don't want to do anything.
