Right signal wont work. Checked fuses and bulbs, they are all good. Was told to replace my flasher relay which was told is under the dash. I cannot for the life of me find it. Please help!

The book says its at the lower left side of the steering column. A quick way to find it is, if the left turn signal is still working, turn that on and listen for the flasher while you are under the dash. It should be a small like plastic box with three wires coming out of it (a lite blue, purple, and black) and it should be making a clicking noise while the left blinker or hazard flasher lights are on. Hope this helps.

But after looking at the wiring diagram, it cannot really be the flasher I am sorry too say. If the flasher was bad neither signal would work. It looks like a bad signal switch or wiring to from the switch. Try the hazard lights and see if those work.

But they are all controlled by the same wire, so the only real test is to see if you have power coming out of the switch on the steering column. It is a dark green wire coming out of the switch, it is highlighted in yellow on this wiring diagram.

Hi, thanks for helping me locate the flasher relay. I replaced it, now my left signal works. It sure was a pain to get the old one out though.

2002 Chevy Venture. No right blinker. I found that the right-side amber daytime running light/turn signal bulb overheated and melted the sidelight assembly.
I replaced the sidelight assembly and all of the right-side bulbs front and back (as instructed from another post). Still, I could not get the right blinker to work.
After reading this post, I turned on my right blinker and then located the turn signal relay under the dash next to the steering column. I could easily feel it clicking. And yes, it looked like it was difficult to remove. Instead of removing it, I gave it a knock with my knuckle and it started working normally. All lights, signals, etc are good. If it fails again, I'll replace the relay. Your suggestion for checking the relay was correct. Thank you!
