i`m guessing you check all the bulbs by turning on the hazard lights and they worked.there fore this should have told you the fuse was good.try changing the signal flasher.it looks the same as the hazard flasher but is a different flasher.its located by the under dash fuse panel.
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
if turn signal does not work, check the bulbs and the flasher. The flasher should be located under the dash near the steering column, but it's not necessary to take the steering wheel off unless the turn signal switch itself is bad.
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
There is a Turn Signal "Flasher" that should be on the Fuse Panel inside the Car. If not it will be in the Fuse Relay Box under the Hood. This is the Problem and needs to be Replaced. Let me know if you need more Help! Please Rate my Response, I need all the Help I can get! Thanks!
