    A/C wont turn off and fuel gauge isnt working

    I have a 92 Deville, and the A/C is constantly on and it will not turn off. It is always blasting heat. The only time it is off is when I turn the car off. The fuel gauge and A/C display also always read C. Just the numeral C, I cannot get it to work. The service engine soon light is always on also. Does anyone know the problem? I think its a computer issue but I am not sure.

    Re: A/C wont turn off and fuel gauge isnt working

    I seem to recall that the blower control unit being bad might give you that error code. I read about it either here or on another forum, www dot cadillacforum dot com Note there is no ess on the end of forum.

    Sorry I can't be more specific.
