Blinker Problems..

I wanted to know where to start...i wanna fix the blinkers on my 87 camaro...i tried to plug in a bulb according to the previous owner everything worked....but i put a buld in and nothing....so i checked for power when i turn the signal on from the front and i get no power to the back...but when i turn my hazards on the front ones just stay solid and dont blink so what can be the problem?

Sounds like an open circuit from where the front turn signal wires branch out to the rears.

Physically locate that area, then using an ohmmeter trace it till you find the open.


Happy Racing!

When you see fog lights on in good weather beware. Low performance driver ahead.

How bout those nitwits too scared to drive without headlights in the daytime, and the nitwits that need headlights for a little rain

Check the TURN B/U fuse.

If good, put your ignition switch in the RUN position.
See if you have 12 volts coming out of the turn flasher at the
PURPLE wire.

If you do, put the switch in the left turn position.
There should be 12 volts at the
LIGHT BLUE wire from the switch.

If there is no voltage on the
LIGHT BLUE wire, replace the switch.


Happy Racing!

Re: Blinker Problems..

The turn signals require a complete circuit to work. If there are bulbs that do not work, then they will not work. It sounds like there is an issue with the wiring. Check the connector on the steering column. Make sure it is connected. Turn on the left turn signal, check the yellow wire for voltage (or the right- dark green). If you have voltage, go to the tail lights. If not, the problem is in the switchin the column. If you have voltage at the connector, check for voltage at the taillight on the same color wire. If there is no voltage, there is a break in the wiring harness.

Check the steering column first, the problem is most likely there.

Other thoughts, Check the flasher. The older models depended on thermodynamics and were notorious for failing. You can upgrade to an electronic flasher for $9.
