I just got this 87 Iroc 2 weeks ago, the right turn signal only lights the rear and does not blink. The front doesnt work at all. When I turn on the hazards all 4 corners work as they are suposed to. I did check and replace the front bulb. The left side, front and rear work. Could the problem be inside the colum? The car only has 90500 miles on it, everything else works except the rear hatch pulldown. But it will be fixed soon, thanks to the info I got from this site. Thanks for any advice.

 

your problem maybe the rear bulb, make sure the connections to the rear turn signal is clean and that the prongs are plugged in as they should, and then check the front wires to make sure there is no rust or deterioration of the wires or the socket. I do believe it's the rear bulb is the problem though.

 

wow thats an odd one

so only the front right doesnt blink, and only with the turn signal switched on?


wierd.....


i would have to presume that if the wire for the right side was cut inside the column then the front right light would not blink with the hazards either


id have to say bad contact in the signal switch assembly


check rear bulbs sockets too


hmmm

 

Cool, thanks I will check the rear in the A.M.

Ya, I checked the rear bulb and it is good also. So my next step was going into the colum. Thank you for your feed back, it really does help.

 

HA! i had the same problem. id turn the left signal on and the back signal light would stay lit up and not blink, and the front one did nothing. but they all worked with the hazards on. but after a few days, the crap just worked again. if you find out your problem, let me kno what is was please. thanks.

 

It sounds like one of your bulbs or ground wires is bad. Something like that in the turn signal circuitry will cause the flasher relay to go haywire.

The hazard switch will make everything like it should because the hazard switch forces the flasher relay to flash.

I would check every bulb and every ground wire on all 4 corners.

 

Keep it simple. did you replace the flasher unit under the dash??? Thyat is the cause of most turn signal problems

 

i have the same problem with my 87 trans am it is in the wiring harness under the hood. If i move the harness it will operate fine for days or seconds one of my winter projects!

 

check the connectors on the lights in question.
If any of the light sockets have green tint in them,just clean the sockets with some sandpaper or steelwool and make sure to add some dielectric grease to them before plugging them back in.
