Location of the Turn Signal Flasher on a 2000 Mazda Protege 1.6by Kyle McBride
Mazda equipped the 2000 Protege DX and LX with a 1.6-liter, four-cylinder engine. A flasher control module, rather than a flasher relay, controls the turn signals and hazard warning lights on your Protege. The flasher control module is the smaller of two white boxes mounted on a bracket up under the dashboard, to the left of the steering column. You'll have to lie on your back on the driver-side floor and look up there with a flashlight to see it.
You can easily damage the lock tab on the control module, so don't remove it unless you're reasonably sure it is bad and you're prepared to replace it. Check the 15A fuse in slot No. 14 in the engine compartment fuse block first if you're experiencing problems with the flashers. The engine compartment fuse block is mounted on the driver side, behind the coolant reservoir bottle.
