I recently aquired an '85 Coupe Deville. I had an 85 Fleetwood years ago, but I can't remember how to get the codes from the heater panel. The symptom I am getting is while operating the car I hear a clicking sound (like a relay) from behind the dash and when the sound is present the engine runs rough or dies and the engine light comes on



I believe I rejected this question a couple weeks ago because I don't remember which 2 wires to cross on the diagnostic port to pull up the codes nor do I remember what the codes stand for.. The last time the system was used was 17 years ago. I have no manuals for a 1985 car.
