If I remember correctly that year has the 80s style digital display unit with the radio on top and heater/ac controls on the bottom.

The actual unit itself could be malfunctioning.There are companies online you can send them out to for repair.

But before doing that I agree some hands on electrical testing is needed so you don't waste money. Here is a link to find a shop near you.
