1977 trans am 4 ways and turn signals dont work the little green arrows dont even come on but when i push the breaks both little green arrows come on at the same time checked bulbs ok fuses ok but cant tell wich one is turn sig.

Sometimes there are 2 flashers, one for the 4-way emergency and the other for turn signals.

Little confused about brake lights turning on/but not flashing. There is a switch on the brake pedal lever or on the clutch lever depending if it has a manual transmission. This switch often gets hit by the drivers feet and dislodged or broken. If it is broken it can do weird things by routing electric to wrong places. Since you have brake lights it is less likely to be bad but worth a look.

Turn signal stalk. Can break in so many ways. One thing to try is to push the 4-way flasher off and on about 20 times. The internal contacts for the flashers share the emergency function. Using the 4-way button can re-shift the contacts back to normal.

check to see if you have a bulb blown out

bad bulb on right side check and replace

DID YOU REPLACE THE BULBS

I would try another flasher relay if it is a 4 connector type. Usually that or a bad ground connection somewhere.

This sounds like it could be that you need to check your bulbs for one that has burnt out or broken. Also, you may need to check to see if you may need to replace your turn signal flasher. Hope this helps.

well first off lets clear a few things 4ways are wired in with the break switch not the turn signal switch so yes even if the turn signals dont work the 4 ways might and vise versa...
if this was a car in my shop i would first check the fuse, if thats ok check the multi funtion switch see if the signal is going out from there, I am sorry now if its the multi funtion switch they are $$$ to replace most of the time when i get this kind of problem in its the multi switch they have plastic tabs in them that push the contacts together and they break off and stop working, but then again if all your turn signals are not working its probly the fuse. post comment if you need more info
good luck

Check your Emergency light switch and turn signal switch.

What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.

If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.

Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.

If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.

But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.

This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.

Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.

Combination switch in the steering column is most likely bad
