okay, so my car is trying to become road ready and there is a problem with my directionals.

when i turn on my hazard lights the left side works and the right doesnt but then when iturn on my parking lights the lights flip and the right side works and the left doesnt. my girlfriends father said that there is probably something wrong with a relay or a switch. i was wondering if some one could help me possibly narrow down this problem and possibly point me in the right direction.

What yr car?

If you turn the key to ON and select LEFT, does the green turn signal indicator on the instrument cluster light up. Do the left front and rear signal lights blink?

When you turn the key to ON and select RIGHT, does the GREEN turn signal indiactor on the insrument cluster light up. Do the right turn signal lights blink? And does the GREEN right indicator blink?

What yr car?

i had a very similar problem a little while ago.
if the dash indicators^ dont work when you signal either way then the problem is either in your turn switch or CPU. if it does the switch is fine, and most likely the CPU is fine. that leaves the bulbs, wires, ect.

when i select left the green blinker light does turn on. however when i select right i hear a blinking faster than the normal blink and the green light does not turn on neither do the directionals. wait it gets weirder when i turn on the solid parking lights only the right front corner turn on. mr steve thinks that the green light on the dash completes the series to the outside blinkers. is there a possibility that because the green bulb is out it would cut power to the outside blinkers. and what is the likelyhood tha my problem is the relay.

Cummon dude. What year?????

On a series four car, the wires that make the green indicators work come from AFTER the CPU. Therefore if the green indicators blinked/worked, then the problem would NOT be the flasher inside the CPU (that's where the flasher is located that causes the blinking).

So. If you select right or left, and the green indicators do not light up, it's more or less obvious that the problem lies inside the CPU. Because if the flasher inside the CPU was good, then when the signal leaves the CPU would cause the green indicators to light up. I'll attach a series four diagram showing what I mean. Later.

IN the attached jpg I tried to show how the left turn output leaves the CPU/FLASHER and then goes to the light bulbs on the right and left side plus how it goes to the green indicator bulb in the cockpit. Colored the output in Purple. Then did the same for the right side signal output from the CPU and colored it red.

Just saying that if the flasher was actually putting out a good signal, then the green indicators in the cockpit would at least light up. They don't for you in one case or the other, indicating the signal is not getting out of the CPU to the front and side turn signals. Make sense?

That dwg of theirs is a bit wrong by the way, but close counts. I'd say bad flasher board inside the CPU which can be replaced with a new one from ?? dealer or Mazdatrix.

I don't think its in the turn signal stalk area. Because when you go to HAZARD and push the button, that bypasses the steering wheel circuit and just sends a ?? gnd to the HAZARD/FLASHER unit and it output power to both left and right signal wires and at the same time power to both green indicators. THAT is NOT happening for you.

Hazard/flasher board is kaput baring someone monkeying up the wiring AT the CPU plugs.

There are things you can prove/eliminate. You could go to the CPU plug called F-55 in the picture and pull it off. Then with a meter, put the meter on the Green/red wire and check for power when you have the key to ON and selected left. IT should be there when you select left. Then check the Green/Yellow wire for power when you select RIGHT. Should be there. IF power shows up on the meter when you do that, then you know that problem lies inside the CPU.

Or to prove the CPU bad again, you could pull F-55 and then jumper the green/red wire to the green/black wire in the plug. Then with key ON and selecting left with the stalk, the left front and rear lights should come on (won't blink, just come on) proving the wiring is good outside of the CPU and that the CPU is corrupt. Same can be by jumpering the green/Yellow to the green/white wire in the F-55 plug and selecting right with the stalk with key ON.

Series five. Uggh. Probably the same as series four as described. I'd have to look at the series five wiring. Still sounds like a bad board in the CPU. Easily replaced.

Here's a series five turn diagram. Similar to the seires four. Some wire color changes and plug number differences. I'd still say bad flasher board in the CPU. No way you could do what I described for a serie four in the other post on the series five. So ignore what I wrote about jumpering wires in the other post.

Your girl friends father is right in that the flasher is a relay of sorts and that's what needs replacing, but it comes on a electrical board . Visit the Mazdatrix site and look at the electrical parts section and look for CPU flasher boards etc.
