TO THE BEST OF MY KNOWLEDGE THERE IS NO PLUG-IN FLASHER BASE FORREPLACEMENT. IT IS IN THE ELECTRONICS MODULE LOCATED JUST TO THELEFT OF THE ASH TRAY PULL OUT, DOWN TOWARDS THE BOTTOM OF THE DASH.THE "FIX" IS REMOVING THE TURN SIGNAL ARM/SWITCH AND REPLACING ITOR TAKING IT APART AND CLEANING THE SWITCH WHICH IS LOCATED IN THESTEERING COLUMN.

I have a '98 TownCar and found that the turn signals and flashers had stoppedworking, but running lights were still good. I ruled-out thelighting control module, by having been told it was very reliable.The turn signal arm is fairly easy to remove. The steering columnshroud (cover) is held together with Phillips screws underneath.But the steering tilt engagement arm will need to be unscrewedbefore the blinker arm can be pulled down and out. The tilt-arm isscrewed in w/some wicked locktite. I had to use vice grips with aswatch of bike-tube rubber to keep from marring the metal. afterthat, the blinker arm can be removed with a 7mm socket, and the 2wiring harnesses can be unplugged. After removing the arm, Icleaned the unit with a can of QD electro-contact cleaner (plasticsafe) from the home center. I did this WITHOUT disassembling theactual blinker-arm unit. Instead I found numerous openings in theplasiic housing to inject the cleaner. After giving the unit alittle time to dry, I plugged the 2 harnesses in back in, andeverything worked like new.
