How do I chnage the headlights on a 1988 Lincoln town car?

The multi funtion switch problly has to be replaced,

The headlight wiring and radio wiring is getting in contact and causing the short.Both the grounds needs to be checked.Because when headlight is off,the radio work's fine.As soon as the headlights are turned on,the radio goes in scan mode.Its clear indication of radio and headlight wiring issue.The wiring's are getting in contact with ant metal surface or both the radio and headlight wire are coming in contact,where they should not.I suggest you to check the headlight and radio wiring diagrams for your lincoln town car.Here is the direct link.Click the link below :---Check out all the 3 links one by one.Radio wiring diagram for 1997 LincolnTown Car?http://technoanswers.blogspot.in/2012/02/radio-wiring-diagram-for-1997-lincoln.html

Hope helps (remember rated and comment this).

there is no headlight fuse, the headlight switch contains a circuit breaker that trips out when a short takes places and then resets when the short goes away.
