All the lights on my trailer work except the driver's side blinker.
I changed the bulbs and still the blinker is not working.
Any ideas why?

Forgot to mention that the ground wires/connections on both the tow vehicle and trailer are brand new and in good shape.
Also, I used a 12-volt tester to check the tow vehicle wiring and it all seems to be working fine.

Make sure that the ground at that light is good. Most lights bolt to the trailer and use the frame as a ground, rust occurs under the mounting causing a bad ground. If you have a separate ground wire going to each light (not likely) check that.

grounds look okay but i'll double check them just in case

thought I'd reply to myself one more time in case anyone out there is having similar trouble with their trailer.
I just got back from Uhaul. Hooked my truck up to 2 different trailers and sure enough, once I hooked to them the driver's side blinker did not work on either of the two trailers.
So now I know my problem is with my truck wiring.
Next step for me is to buy a T-connector and give that a try....will keep you posted.

Not a chevy....
My truck is a Ford Ranger
Hopefully a new T Connector will fix my problem....we'll see.
Had the exact same problem last year, check your truck wire harness. Might have some corrosion.

New T Connector (truck wire harness) did the trick....thanks.
This is the 3rd T connector I've had to put on my Ford in the 5 years I've had it.
