"blinker problem" i used to have to flick my leaver up & down to make them blink. 92 buick rd master estate.

theres 2 blinkers in the car that look the same, switch them and see if you still have 4 ways, and if the turn signals still dont work, if the problem is reversed, go buy a new flasher throw out the bad one, in a dark area, check to see that all of the lights work , dont assume that because theres more than one bulb that all is ok replace any or all that dont work

The flasher unit is probably bad. It is under the dash and silver in color about 1 inch in diameter and there should be 2 of them one for the 4 way and the other for the signals. Turn the 4 ways on and fell each flasher unit and you can fell it clicking. The other is the turn signal flasher. Take it out, some have 2 prongs and some 3. Go to the parts store and get one that matches it and that should fix it.

Change the 4 way flasher with the turn signal flasher 2 c if it's just the flasher ! They have 2 flashers..& tell old blinker but 2 go kie a flite..

It's broken! Bring your '92 Buick Roadmaster to a mechanic!

either a bulb is out, or the relay is bad on it,

i had the same issue on my 1992 LeSABRE

I think you need a new turn signal switch.

Do you change your blinker fluid every 3,000 blinks?
