00 buick lesabre turn signal problem

i have a 00 buick lesabre that i am having problem with no turn signals. it first started with the infamas fast blinker on drivers side, so i replaced all the bulbs , so when that did not fix the problem, i thought it was the socket, but it turned out ok, so i replaced the flasher and after that, i have no blinkes at all, haz work but no blinkers. i tryed old flasher but still no blinkers. i checked the fuse that runs the blinkers, it was ok.i replaced it anyway.is there any hidden fuse that i missed somewhere,any sugestons ? thanks.

Try looking under rear seat- on driver's side at the rear fuse block- there are lamp circuit fuses in there...

the only fuse that i could find that was marked for the turn sig /haz was under the back seat, and that is the one i replaced wich looked fine but you never know. i am wondering if there is a fuse in the colum or hidden under the dash that is not able to see.

Should also be a related fuse in the under hood fuse block

Check IGN 1 Fuse 12 10 amp Rear Fuses
Fuse 36 15 A Rear Fuses Tsignal and Hazard
Stop lights are Fuse 19 15 A.

That's all I can see.

Thanks for coming back and telling us what you found.

I'd also mention to make sure you are using the correct bulbs. I've seen a number of LeSabre's cruising around with rear lamp lenses melted because someone used the wrong bulb. You don't want to overheat your lenses or potentially blow a fuse again.

The owner's manual for my 00 specifies the following:

Rear Tail/stop/turn signal (rear corners) - Bulb 3357
Trunk mounted tail lamps - Bulb 194
Trunk Mounted Back-Up lamps - Bulb 3057

Front Turn Signal - 3157

I am having this same issue and have changed the fuses listed in this thread. No dice. Any further suggestions? Thanks!
