Question about 1990 Cadillac Deville
Whenever the car is started the climate control center and the fuel control center both fail to operate. After a 10 sec wait a "d" is displayed on both panels. I have search for solutions to this problem such as checking the diagnostic errors, however the climate controls do not work, which prevents me from accessing these codes. Any help will be greatly appreciated.
The climate control is intergrated through the pcm and ecm i would advise you to take the vehicle to the service shop they have a diagnostic scanner that will access the ecm and either clear a code that prevents the climate control from working or find a more severe problem that requires you to replace the hole unit. please rate this solution. thank you and good luck.
