turn signal flasher question

[Barracudadan]

Is the turn signal flasher also the hazzard flasher on a 72 Barracuda? I thought they are separate parts I found the one up by the brake pedal which I think is the hazzard flasher but I can`t find any other flashers underneath. My turn signals and dash lights are not working now and I am having trouble finding the cause of the problems.

The turn signal flasher is behind the dash. Take out the ashtray assembly and it should be to the right of that. At least it was on my car.

  Look behind the ashtray

Correct the turn signal is behind the ashtray and is held on by a little tab.  If your car has air conditioning - you will have to be creative with your hand and you WILL say a few nice words trying to get you hand on it.

The emergency flasher is a separate circuit and it's located on the steering column by the fuse box.  You will have to stand on your head to access this one.

Good luck!

Thanks everyone, I will have to look better around the ashtray. I have another question when I put a simple 12 volt test light on the fuse for the hazzards and pulled out the hazzard switch I could hear the flasher working and the test bulb was blinking would this indicate that the flasher is ok? Can I do the same test for the turn signal flasher? I am still trying to pinpont the source of my turn signals and interior lights not working.

Have you checked all your bulbs?  Look for corrosion and fix/clean as needed.  The bi-metal flashers work on resistance and if the circuit does have any resistance the unit doesn't work.  The flashers are cheap (Under $8.00) and available at your local parts store.

All the bulbs should be good but I will check them again.

Found it! I switched it with the hazzard flasher and used my test light to check it. I can get it to make the lights flash when I put the test light on the fuse at the fuse block. So I am assuming the flashers are ok. I have power to the dimmer switch when the head lights are on which I also assume is correct. After that I am stumped.Is it safe to say my problem is somewhere after the dimmer switch? I can really use some suggestions this is starting to drive me crazy!
Last thing I noticed when I put the test light on 1 side of the fuse for the hazzards it lights however when I put the tester on the other side of the fuse it wont light is that normal?

Your fuse is no good, replace it.

it`s not the fuse!

Ok Here is my latest I was getting power to the dimmer but not anymore. I checked for power at the orange connector for the instrument lights no power there and at the turn signal switch no power there as well. Car still starts I am getting fed up with this and you know how that goes can`t even think straight anymore! Need help S.O.S!

Do you have access to a wiring schematic for your car?  I have one for the '73 e-bodies that I will scan tonight and post here if that will help.

Sit back - have a cool beverage and get back at it checking the grounds.  By the way are all the sockets for the bulbs in the housings.  On some cars, especially the Challenger's the rear housings are part of the ground circuit.  If the socket is out of the housing, feedback in the system occurs and the lights really do weird things.

Good luck - you are close.

Thanks for the encouraging words but I have to give up the fight for today I`ve had enough. I do have a schematic. All the bulbs are in I do have the instrument light bar out but I put an alligator clip on it to provide a ground. I`m just fed up everything worked great untill I opened up the damn dash to get to the voltage limiter. Now I have no power to turn signal switch WTF! I just don`t get it! I`m beginning to wonder if the problem is down at the fuse block.

Do you have an Ohm meter? With the power to the lights turned off, test the resistance between to two terminals of the dimmer switch that don't have power to them. It should change as you rotate the knob. My guess is you will see infinite resistance and rotating the knob will have no affect. It is quite common for these dimmer switches to give up the ghost. This however doesn't explain the turn signal problem.

Does it matter which 2 terminals to try? I`m guessing do the 2 outside ones? I`ll have to try it tomorrow,but at my last attempt I was not getting any power to the dimmer switch and I tried to jump it out and completely bypass it with no luck which leads me to believe my problem is before the dimmer. I think I will make another post about the turn signal switch problem, I hate making a bunch of posts like this but I am getting nowhere fast on this and when I find the problem I know it`s going to be something really stupid!
