Your grounding. have you replaced the radio lately? go back to the last work done on it and look for the wire that is grounding.

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

No brake light no running lights no dash lights if u play with the headlight switch u can get every thing to work but brake lights but when u press the brake it turns your headlights off


Hi,
I'll make it brief( something wrong w/ my ISP ).
You got problem in the light switch assembly, the plastic cam is already melted and failed to push the metal contactors to the contact points. Replace is necessary.
The brake and headlight problem, better check the shorted wire in the relay and fuse box in the engine area, there is a shorted wire that stealing the power of the headlight relay, thus it turns off when you step on brakes.

Recommendation: Better have a tech to check on that, a total check up of the lighting and brake light harness is required, the main harness under your steering must be check thoroughly.

Hope that helps!

Keep blowing fuses for the taillights when i turn on the headlights...everything else works, even the headlights..what could this be? a short in the wiring? bad headlight switch?


short in the wiring. More or less a positive wire is grounding on the body of the vehicle. you are going to have to trace it from the switch to the lights to see where the wire is broken, stripped , burnt or touching.

When i turn on my headlights it blows the fuse but all the other lights work till you turn on the headlights


You have a short to ground somewhere. I would start at your headlights and make sure the wires are in good condition. From there I would look at your switch since it's the most used in the system.

Headlight headache


Soounds like you have a wire problem. Look under your dash at the headlight switch and the connector for any melting....repair as necessary. Look also around the headlight wiring....sounds like you have a wire that is shorting out.

89 Thunderbird, no tail lights


Having the same issue somewhat. Tail lights and dash lights quit. Checked the headlight switch wiring harness by looping all other prong holes back to the main power and they all work, so mine must be the switch. Having a real hard time finding a switch that matches the old one, even though they say it is a replacement. I paid the $25 at www.alldatadiy.com and they have quite a few wiring diagrams for the car.
