Where is the turn signal flasher located in a 1999 Cadillac Deville?

Answer 1

AnswerUnder the dash, driver's side. AnswerTo the misinformed Cadillac 1999 deville only has one flasher and if the emergincy works its not the flasher. If the turn signal don't work its in the switch on the steering column. And it could cost as much as 200+ to repair. So much for owning a cadillac. Answeron the 1999 and earlier deville there are two flasher relays. one controls the emergency flasher and the other controls the blinkers. the one for the blinkers are located under the instrument panel on the left side of the steering wheel and the emergency flasher is located on the other side.

i brought the book after nobody could tell me anything besides its an electronic flasher and the switch is the problem.

AnswerThe 1994-1999 deville share the same body configuration except for cosmetic and enginge changes and this procedure works on the 1999 Deville. On my 1996 DeVille, the flasher is a 3 prong, square unit that is located just above the emergency break pedal on the inside face of the lower dash panel. To replace this flasher you should start by removing the 2, 9/32" bolt head retaining screws holding the black access panel just above the break pedal. Lay down on your back and look up inside the dash. You may find the round hazard flasher high just above your head, this is not it. Stick you hand up along the panel in front of the emergency break pedal just behind the trunk release button. Locate with your hand a 2 inch long square relay box and move it to unhook it from it's clip. (If the flasher is the factory flasher it will have a metal clip retaining it under the dash. Your new part will not have this clip.) Route the old flasher and wire down so that it hangs from under the dash. Now you can see it and disconnect it. There are multiple connectors, but only three of them line-up and actually have metal receptors inside the socket. Take note of the removal of the flasher so you are not confused during reinstallation. I think the other connectors are for additional features not needed in the US. Take the part to the parts store or just replace with new one. Relocate the flasher safely up in the dash in relatively the same place and make sure it won't move around. return the black panel to its position above the break pedal and replace the 2, 9/32" retaining screws.

More Detail

First thanks to those who put up the above answer. This worked and I feel great that I both saved myself probably a $200 fleecing for a $15 part. My Caddy is a 99 Deville Concourse. Here's my experience

Yes it's true. If your hazard lights work, but your turn signals don't, it's the flasher part.

The part is a black rectangular cube about an 1-1/2" deep with 3 metal prongs.

It is in fact located in front of the emergency brake and above the hood release, but I still found it difficult to find, but it was there. It was attached to the inside of the panel, and had a socket plug with wires attached to it. I successfully unplugged the part, but the part was still up there. The wires dangled down and but there were more holes in the socket than prongs on the part, and as above, only 3 have metal connectors in there. I plugged it in and my flashers worked! I'm so happy. I ripped off the old one, then found that there is a clip the you can brace the new one into.

You can do this!

AnswerYes, it is difficult to find, just grab the wires and follow them, on my 98 Deville, the flasher was to the front & outside of the e-brake, behind the metel side of the cabin! It IS THERE, just difficult to find.

Thanks to those above me who pointed this out! :)
