Did you check the fuse? Anyway, it's impossible to answer your question. Re-ask and be very descriptive about what the signals will and won't do.
check your fuse
Check the bulb it is double filamented with the smaller being for the stop and turn signals
The only fix is to remove the head and replace the gasket.
You fix it
I have the same issue on my 81 El Camino and I am still researching the issue but if U happen to fix it then please let me know at dave_8423@hotmail.com...Thanks
Replace the radio.
Take it to a mechanic, get a copy of the service manual and do it yourself.

check the recalls there is something in there about tail light and signals
It could be as simple as a fuse. Or as hard as a multi-funtion switch. Which means the switch for your turn signals.
Just keep on power it on
