Question about 2007 Mercury Grand Marquis GS Sedan
I'm told the flasher in this case is built-in the LCM or Lighting Control Module's board. Since the flasher can not be replaced, how can the diode that senses change in bulbs resistance, can be disabled?
It would probably be easier and a better idea to just get the correct bulbs.
The use of the wrong bulb can cause the flasher to flash too fast or too slow. Turn signals on American cars use either a 1257 or a 1034 bulb, which are interchangeable. A 1257 bulb draws more current than a 1034, however and if it is used in place of a 1034, the flasher will flash faster. If a 1034 bulb is used in place of an 1157 bulb, it will flash slower.
