Re: How to check codes in 1989?
Yes, hold the off and warmer buttons at the same time. Continue to hold them until the climate display shows any codes. Be aware getting the codes is one thing, understanding and being able to fault trace them is quite another. I always reccomend having the Cadillac factory service manual to do this checking. knowing what each code refers to can help even the non mechanic relay info to the ultimate repairer and possibly speed up diagnostic time which could save money.
