So I noticed that my front driver blinker was not working. Thought to myself ok just replaced the bad bulb. Pop out the old and in with the new and still nothing. I also noticed that the light for the blinker on my dash wasnt working. So basically the right side blinkers work fine including the dash light but on the left side or driver side, only the rear blinker works. No front blinker and no dash indicator. I already pulled out my cluster and swapped that bulb for a good one but still nothing. Where should I go from here. Its never an easy fix on this truck it seems like. Guess I should include it's a 1993 F150 XLT 5.0 automatic 4WD

 

do you have 12 volts at the bulb socket?? Get a meter and a wiring diagram/schematic and test each socket for 12vDC. Then you will have a fact to help you trouble shoot the problem. Never a good idea to swap things, unless you have a valid reason to do so.

 

Work the hazard switch several times. Click this, read the caption, & follow the links in it:
