Cadillac Repair: 1987 Cadillac Eldorado, cadillac eldorado, computer display

Question
two issues...1st the computer display is out however the computer is still functioning & i can still control options such as a/c and heat. does this mean its time for a new computer? 2nd when the car is off a/c is still blowing even after i disconnect the battery. any suggestions?

Answer
On any of the displays do you see any of these being displayed:

-c
-d
-151


The blower control motor needs to be tested to determine if it is at fault or the AC/Heater programmer is at fault.

Both items are EASILY fixed.
