Flashers believe it or not are often responsible for working on one side only. I would change both out just as a starting point. I'm assuming the car is running too. If off there may not be enough power generated to flash. I run into this regularly on old cars.
One important thing to note is parking lamps are done by a separate filament and are not handled by the turn signal or hazard switch.
There are two flasher cans. One for turn signals and one for hazards.
When you turn on the hazard switch there are three things that happen:
Power from the hazard flasher gets jumped to the Front Left and Front Right turn signal lamps
The Rear Left and Rear Right signal lamps connection with the brake stop switch is severed.
Power from the hazard flasher gets jumped to the Rear Left and Rear Right signal lamps.
As you can see, the rear signals are a little more tricky because they double as a brake lamp. Even when making a normal left or right signal, the "cancelling cam" first breaks connection with the brake switch before apply power from the flasher. Also, Both the brake switch and hazard switch rely on the "cancelling cam" and it resting in the center position for powering the rear signal/brake lamps.
Ok, thankyou for the information regarding the flasher issue Im having.
I had another look at her today with the objective of it not beating me.
I checked the loom coming from the firewall connector blocks. The wire for the right turn signal is black with tan stripe.
I put a meter across this from end connector end all the way to the plug that goes into bulb.
There was continuity , so cable is fine.
Like i say, rear left and right turn signals work fine.
Front left works fine.
Front right, no good.
In the end, i spliced a wire from the brown wire coming from the steering coloumn connector block.
This flashed a bulb when operating right signals.
I took the wire all the way to front right signal bulb.
Bingo.. she works.
Both front signals work
Both rear signals work
Headlights and tail lights work and dip/main
parking lights work
side flashers work
Reverse lights work
Brake lights work
I took her out for a drive, all working great, however....
I noticed that when i apply brake, im getting front right signal come on... darn it.
