#1 of 10 fast flash turn signal 2005 Crown Victoria
Feb 19, 2010 (1:37 pm)
Anyone know what to check for as to why my turn signal flashes fast? This happens only on left turns. I switched the turn signal bulbs on the left side with the ones on the right (both front and rear), but it didn't solve the problem. The emergency flasher works fine (no fast flash, left and right). After reading in another forum that a blower motor speed can cause fast flash, I turned the blower fan to maximum and minimum speeds, but it had no effect on the flash speed. I'm thinking an electrical connection may have jarred loose from hitting all the potholes lately.

If the faster flashing occurs both front and back, count your blessings & continue on.

Try removing the taillight on that side and removing the sockets from the lens then try the turn signal again. You may find one of the bulbs is not working. There are two bulbs in the taillight and it is hard to tell if one is not working when they are inside the lens.

It may be an electrical issue as you said. Check further to source the route of the problem.

I finally figured out what was causing the fast flash: it was a burned-out bulb. I didn't realize there were two signal bulbs on each side in the rear. When I checked the left rear, I saw blinking and assumed the bulb was OK but one of the two was actually out. When the bad one was replaced, fast flash ended. You may need to make sure that both bulbs on each side (4 in total for the back) are blinking. It's hard to see through the red cover and with the flashing bulb.

A fast flashing directional indicator is usually indicative of a burned out bulb.
If this is not the case, make sure that one of the bulbs has not been replace with a LED replacement. This will cause a fast flash. You can get a resistor to place in circuit with LED's to make the flasher cycle normally. The only thing that will make your turn signals flash fast is a lack of resistance, as in a burned out bulb or a replacement LED unit.
Also, if there is a faulty ground, this will cause dim illumination. Make sure that there is a solid, rust free & dry connection of the ground wire.
