The turn signal on my 93 Daytona Iroc is acting up. Usually, around the heat of the day, the turn signals will completely stop working. The only way they will work is by turning the lights on and pulling the dimer switch back. The right front signal won't work at all requardless even if you change the bulb. The indicator will flash wildly as if you have a bad bulb all the time that it is working. I suspect that this is due to a bad socket, wiring, etc. Has anyone encountered this problem before? I have replaced the turn signal switch but the problem continues.

 

Mine is acting the same way- I am going to try a flasher unit first then if that don't do it I have a new turn signal switch I can put in. Mike

 

Sounds like a wiring problem to me, good luck.
