02 F 150 V8 4.6L rear driverside blinker does not work and blinker signal on dash flashes 10x faster than the right side signal HELP?
Probably a burned out bulb. Many vehicles do that to draw attention to the fact that a bulb is burned out. it blinks realy fast just to let you know the light bulb is out. turn on your emergency flashers, look at all the lights to see which one is not blinking and replace it, you will be good as new. It sounds like you have a faulty bulb, and the system is signaling you.
If you are referring to the blinker indicators on the dash board, it is because one the signal light bulbs need to be replaced. The side that blinks faster is the side where the bulb needs to be replaced. Turn the blinker on and walk around the car to see if it is the rear or front bulb that needs replacement.
How would you fix your blinkers if it isn't the fuse and they don't work manually by hitting the blinker arm?
When you push your horn on your 98 silverado your right blinker lights up but no horn and your right head light flashes with the right turn signal and is dim the rest of the time?
If your blinker is blinking at a faster rate than normal, it usually means that one of the bulbs is out. For example, if the left turn signal blinks faster than usual, check either the front or the rear left turn signal. If both turn signals seem okay, check the front left parking light. (this is the front orange light that is on when your headlights are on)
