Under the hood in the fuse box.
The turn signal flasher relay on the 1999 Honda Odyssey is located under the driver-side dashboard. The relay is tucked near the cabin fuse box.
The signal relay is attached to the emergency flasher on the center of the dash. Gently pry out the flasher and the relay is attached at the rear.
According to my Haynes repair manual, it is under the dash to the right of the steering column.
Yes All Aurora are a Like 1995-1996-1997-1998-1999
well first check the fuse if good the relay is behind the dash so climb under streering wheel and look up behind the dash to see the relays there.
broken turn signal switch assemblyreplace it
Reach behind the bumper of the 99 Cavalier. There are two nuts that hold the turn signal assembly in. Remove the nuts to take the assembly off and replace it.
its under the steering wheel
I found out through a Chevy dealer mechanic that this year/make/model Chevy doesnot have a flasher in it. If the turn signal doesnot work it will be the turn signal switch in the steering wheel.
The turn signal flasher on a 99 Bonneville is either behind or next to the fuse box. Remove the plastic panel mounted with 3 bolts left of the steering column to be able to see it.
