Looking for some advice from those of you experienced with these things.
We have a 2005 Ford F150 and a Springdale 260LE trailer.
Everything was working fine for 6 months. Today we hooked up and went to check the lights and the rear left light does not work properly.
Turn signal - none
Breaking - none
Hazard - a dim solid glow, no flash
All lights work fine on the tow vehicle whether trailer is hooked up or not.
We swapped bulbs from the left to the right on the trailer and the problem stays with the left side so not a bulb issue.
Per another
thread I had purchased a heavy duty turn two pin flasher and we connected it directly to pins 3 and 4 of the trailer umbilical plug. All lights on the trailer work fine including both rear lights which flash as they should, so not an issue with trailer wiring or 7-way plug.
Now we're looking at the F150. But since the hazards and turn signals work fine on the truck, we are assuming all fuses are good. Everything worked fine before so we're assuming our flasher can support the extra lights on the trailer? But now it's not working so why?
Hubby has gone to buy a replacement 5 pin heavy duty flasher for the truck just to see if that makes a difference but otherwise we are baffled. Any ideas?
