Have a 1990 Buick Lesabre. No turn signals, but I do have hazard lights. Just had the signal switched replaced as well as the fuse, and still no signals.
When the signal switch is activated, and you have the brakes on, it does cut off the brake lights in the direction of the signal. But the lights wont activate. Checked all the bulbs, even replaced some of the brake bulbs.
Not sure what it could be. Any help will be appreciated.

there is a flasher under the dash put your 4 ways on and listen for the tick noise find the flasher unit under dash area driver side there is two one for the 4 ways and 1 for turn signals now that you have found them turn on working signal touch the flasher unit you will feel it pulse and hear the noise when you have the one pulseing on working signal this will need replacing can also be in fuse area have a good day
Sounds like you burned a fuseable link wire. Some of the circuits are protected by a fuseable link in addition to the regular fuses you can see. Check the wires at the starter with a test light or meter - one of them may be burned inside.
the turn signal flasher is a small canister-shaped or rectangular unit located under the dash, either in a clip adjacent to the steering column or in the convenience center which is located located under the right side of the dashboard and houses relays and other components. The fuse.faulty flasher unit a broken switch or a loose or open wire. We have eliminated the switch, I would check all fuses inside and out, you can replace the flasher with the hazard flasher as if I remember correctly they are the same shape and size, then it is just a matter with a tester light running it from the column to the sockets and finding the break. Hope this helps Tim
Yes all the wiring needs to be complete. Then all the bulbs must be inserted into sockets. left side marker right side front turn back turn reverse lights brake light everything. Then make sure they all work. The problem could even be a bulb thats on the fritz ready to blow but still on and dim little light. if that's all fine then it's probably your flasher. There are 2 flashers one for turn and one for hazards but I think they are the same but still separate. located under dash on either side of the steering wheel. The flasher closest to the door is up in there pretty far it's size is about like a 2 liter cap and it's silver. good luck
I think that your flasher is bad I believe that the 4-ways flasher is a seperate flasher unit it should be in the fuse box and look like the 4-way flasher , to find the flasher turn on the 4-ways and you can feel it or hear it flashing and lok for the flasher for the turn signals
