Where do I find the signal flasher unit in my 1986 buick century. I found the 4 way flasher thinking the signal unit would be close by. I have under the dash all torn apart but cannot find it anywhere. Hoping you can help. Aaron
PS I did try some research only to find that it might be on the right side of the steering colum but I tried there but still no luck.
Look behind the panel on the right side about the height of where your kneecap rides.
I found my silver flasher tucked back and up being CLipped up out of the way. I never found my 4-ways (did Hear it!) just my 2way and only after I contorted into strange shapes with my head stuck back as far as I could get it and facing skyward with my legs trying to hang onto the back of the seats!
I hope yours will be easier to find than my 94/95 was.
I was told my 4-ways were on the left and that my 2ways were next to it -- not so! Heard the emergency near center and to left of steering column, never found! BUT, I do have all flashers NOW!!!! You'll get it tooo!

you should find the flasher unit under the dash on the drivers side,it may be a square or round unit with a connector plug on the top, when you remove the connector plug there are three terminals on the unit......hope this helps......cheers.
Time to change the flasher unit, it's usually close to the drivers side of vehicle and behind a fuse box access panel and will have something like "12v 23/98W " on it. It's a largish cube shaped componant and may be water damaged !
there is a flasher for both 4 way & regular turn signals ( check to make sure the bulbs are good
the backs are easy >>> Just step on the brake, If the lights light up the bulbs are good you my have to remove the bulbs one at a time in the front check your ground wires to the lights if everything is good replace the flasher unit if that fails replace the turn signal switch
Check near the fuse box and the left side under the dash. There are two flasers in a car, one for the hazards and one for the turn signals. You are on the right track for if the hazards are working the bulbs and wiring to the bulbs are eliminated. Once you replace the flasher your problem should be fixed. When checking for the flasher remember they sometimes are clipped or taped up, so feel around as well as looking.
The way to check if you need a flasher is to turn on your 4-ways (emergency flashers), if you have emergency -- shut that off and then try both turn signals. I had a flash on my right (OK); The left had lights on both front and rear with no FLASH, which meant that the 2way flasher was not function.
I was told to turn my 4-ways on and it would help me locate my 2way ------ NOT So. I bent, twisted, readjusted and thought some ugly words, but it wasn't so bad once I found it (even though I disasembled almost all the bottom panels of the dash) so here's my version:
I just replaced my 2 way flasher: it was to the right of the steering column and was tucked up high and Clipped in the approximate vicinity where your right kneecap would be as you drive, behind the dash panel. Look for a silver flasher, the one I replaced it with was yellow. My 4-way I Heard on the left side of the column.
Best to you, it wasn't much fun not being able to see, not knowing what I was doing, and not being a young person anymore! But the ol' gal got it done, NOW THE COPS won't be following me for that anymore!!! ...................leathers
The Buick Century uses separate relays for the hazard warning and turn signal functions. The turn signal relay is located on the accelerator pedal bracket, and the 4-way flasher relay is located on the convenience center near the left kick panel. Try switching these two relays with one another to see if your turn signals work instead of your 4-ways.
