in mark 8's they use a controler to make flashers flash. this module has gone bad
it might be the hazard switch all the blinker circuit runs through it.
Assuming you checked all the bulbs and fuses, it sounds like the signal switch is shot.
the blinker relay is probably bad
Could be the control stick for the blinkers. If the lights work, try replacing the stick or checking out the signal path for that blinker
Make sure the bulbs are good.
All Bulbs were replaced. fuses all checked, relay switch new and flasher, Also when the relay switch is in it gets really hot. Any suggestions
I checked fuses and replaced blown fuses and now it won't start.
The blinker relay is under the dash, on the passenger side of the steering column. It is under a black cover with a small number of fuses.
GO AND BUY I NEW light bulb !
has anyone checked the fuses and bulbs?
Check the fuses first.
check fuses under dash panel and for short if wired for trailer
