I have a 1999 Ford F-150 4wheel 4.6
Last night I realized my front turn signal had stopped working.
When I go to turn on my front turn signal the signal does not display on the cluster. Also it clicks really fast. My left turn signal works but the right doesn't.
The front right signal doesn't work but the back blinks like twice as fast than normal. I changed out the bulb but it still won't work. I checked all the fuses but there good too. What do I do?!

 

do you hear the clicking noise of the flasher? that may be your issue

 

The right front bulb is blown or there's a wiring issue in the socket. Flasher is fine if the left side works.

 

Well the bulb is good I did replace that. If it is a wiring issue, any advice on how to fix it?

 

A common failure of Ford trucks of this age was the multi function switch in the steering column. This affects turn signals and 4 way flashers. Your description of the signals is what I had happen on my 98. I had mine done at the dealer. I was in and out in about an hour.

 

A common problem is some of the wires pulling out of the connector at the multi-function switch up in the steering column, causing all sorts of strange lighting problems. It's a pretty simple repair ...

I was having a similar problem, the left turn ligth was not working but funny thing was that when I turned on the park lamps the front left light was on! just the turn signal didn't work! it was driving me crazy!

I pull out the bulb, it was ok but I replace it anyway and it started working, I put everything back on and again! turn light not working... anyway long story short, it was the bulb socket that was faulty.
