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

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
