BLINKERS DON`T WORK

Make sure all outside blinkers are flashing at one speed, if not check the bulbs and all connections, If that doesn't work check flasher

check the light switch .see if the wires have been pulled out if not prolly a bad switch.

I would say that the contact points in the blinker handle have had excessive current flow and they are burnt or bent so as not to make contact. Possible invest in a new indicator switch assy.

There is more than one flasher. One is for hazards and the other flasher is for directional signals. They are located under dash just left and right of the steering column. Don't go tearing up the steering column, then you are asking for trouble. Try the least expensive and labor intensive fix first.

There should be a flasher unit on the fuse box under the dash for the turn signals and another behind the dimmer switch for the hazards.
Sometimes one of the flashers is behind the fuse box in the glove compartment if equipped.
Don't be surprised if the flasher is not the problem. Most of the time the problem is the multi-function switch on the column.
There are stories online about using WD40 to take care of the switch problem.

You will need the wiring diagrasm, we do not have them but you can access them here www.alldatadiy.com

blinkers sounds like the flasher unit is not working. It's located under dash. Also check for burnt out bulbs.
Rear defrost, or rear defogger?: Your defogger for the rear window would run off a relay, probably located in the fuse panel of your car. Often, the connections at the rear window get broke or disconnected.
Front defrost: does your heater blower work?

Check the switch

Have you removed the bulbs and checked them and the sockets for corrosion? Also make sure they are locked into place properly. Another thing is to check the flasher relays under your das by the fuse box to make sure they are properly seated.

on the brake lights, check to be sure the switch located at the top of the brake pedal isn't stuck, you can Jumper the switch to see if that works,
