First post. Glad to be here. I recently purchased a 1985 F150 Single Cab 4x4 with 351W Engine. Shortly after purchase the blinkers started acting up. I replaced the Flasher Relay and all fuses. Every blinker works except for the Driver's Side Front. Hazards all function as well. When left turn signal is engaged the dash light does not come on, but there is still the "blinking sound". I've tried researching what could be the problem but haven't seen any clear answers. Any help is greatly appreciated.

Yo 85,
I THINK THE 85 have a seperate flasher for turn signals and hazards. Check for one behind the fuse panel, believe it is for hazards.

One Indicator light doesn't light ..
- ***Check the bulb and socket (for corrosion & Wiring issues) on the Front driver side***
- ***Check the left indicator light bulb***
- Check the flasher by substitution
