Do you have a two terminal bulb in it? Also to check the bulb you can take the left bulb and install it on the right side see if it works.

What type of pug are you using? If it's a 7 prong plug ,one of the prongs could be broken.

this probably won't help. but the other day when neither left nor right blinkers worked for me, I turned on the 4-way flashers--just to see if they worked--and they worked. After that my blinkers came back online. I have no idea why that was, but it worked.

the bulbs could be good but the fitting they plug into dirty / corroded and in need of cleaning . now at auto zone when i buy bulbs they say to buy a little tube of grease to apply into fitting to prevent corrosion / build up

do they work on the truck? if not check fuses.. heck check them anyway some vehicles have seperate fuses for the trilaer lights

Definitely check your truck fuses. All newer trucks (1999 and newer) have seperate fuses for the trailer turn signals. They are labeled. Im pretty sure that will fix your problem. 9 times out of 10 thats what it is.

this happened to me at the beginning of Spring. It was the ground wire.

I've learned to apply small dabs of die-electric grease to every contact on the plug that goes from trailer-truck.
Use a paper clip to do it with, or a toothpick, just a small amount.
Then the adapter I use also has lighted LED's that help me diagnose if current is coming through the truck to the plug...
If the LED is lit that means the truck end is good and the problem's in the trailer, vice-versa if the LED does not light up
it means my problem lies in the truck.
Better still WHEN the LED lights up I know right away which WIRE is causing the problem (other than ground),
all this helps me a LOT, it looks like one of these:
