[QUOTE=Wildman]I have a 1978 450 SEL I'm looking to sell, and with all of the issues:
Fan constantly blows hot air (probably $600 servo problem)
Automatic antenna does not work
Short in electrical system requires disconnecting battery nightly


If your servo is jammed, it will try to return to its "park" position and run down the battery. If you turn the car off and listen with the hood up and hear the servo motor running without shutting down after 10-15 seconds, you've found your battery drain problem.
