Usually when ones turn signal is blinking fast its telling you that a turn signal bulb (and in some cases a brake light bulb) is out. If it blinks fast when you turn on the the left signal the burnt out bulb is on that side of the vehicle (could be front or rear bulb so you'll have to check). And vice versa
Start with checking the left rear brake light bulb.
The right front bulb is probably burned out.
if it only flashes fast on one side, you have bulb out on that side. If both sides are fast, change the flasher
turn on your turn signal and look for the bulb that's not blinkingAnswerThe light that needs to be replaced will be the one that is not flashing. You need to turn on your turn signal and walk around the vehicle to see which one is not flashing.
I have a 1996 Grand Marquis. If one of the brake lights goes out the signal on that side flashes faster. I would check the brake/tail lamps.
The turn signal and brake light use the same bulb. When you get a fast flash, it is from a reduced electrical load being placed on the flasher unit due to a burned bulb. Replace the bulb and this should fix your problem.
the front bulb needs to be replaced.
You need to replace the failed TURN SIGNAL lamp. Select turn signal selector to direction which flashes fast then check which exterior light is out. Go to any auto parts store. The light usually costs under $5 and can be replaced easily.
You need to replace the turn signal bulb. When bulb is burnt out the turn signal will flash faster.
you have a blown bulb, some vehicles use a double filiment bulb that operates the turn signal and brake light
Check your bulb, In the rear of the Generation 4 Ford Taurus, they use a single Dual filament bulb for the marker, turn signal, and brake functions. Chances are your bulb is burnt out and needs replacement.
Bad bulb socket? Broken Wire to socket?
