    Service Now light

    I have a 1984 Fleetwood Brougham and the "service now" light is on. Can anyone tell me what it could be. Also the air is not blowing and my antenna is stuck up. If anyone could help me that would be great. Thanks in advance!

    You have to read out the trouble codes.
    If you don't know how to look at this video:

    I would never put up with an antenna with an attitude! and its not windy here either.


    Its one thing to be able to retrieve the code BUT you need the factory service manual to walk you thru the diagnosis and repair. If you are going to drive this old of a car, you MUST have the manual mainly because the technician is years younger than the car!!!

    Post the codes once you have them. We'll talk you through the start of the diagnosis. I have the 84 FSM to help until you get yours.
