I have been trying to chase down this issue for about a month. My hazard fuse blows out every time my right turnsignal is on and I am moving (does not happen when I am sitting still). The fuse will not blow out when I have it on left or in any situation when I am not moving, same goes with the hazards. I have changed out the switch which did not fix it. Also my Turnsignal circut still makes the click noise when the fuse is blown. I am thinking it is a wire shorting out when It shifts around on the right side turnsignal circuit.

I am just looking for suggestions before I resort to tearing my interior apart trying to fix this problem. From what I have seen in searching turn signal fuse blowing is common but none of the results I have found searching have helped.

Thanks,

 

Two fuse make the signals work. Hazard and Turn. Turn makes the *flasher* work click, click. Hazard actually feeds the power thru the contacts on the flasher to the lights themselves.

That explains why you still hear click, click but no lights work.

Seems you have a dead short at one of the front or rear lights on the right side. Which one? Got me. Unplug one bulb holder at a time and find out?? Say yes. Not one bulb at a time, but one bulb holder at a time.

 

Yea I actually already tried that. I unplugged both the front turn signal and the back one at a time and it still blew out. I am afraid the short may be in the dash (The dash wiring has seemed to be acting up alot)

 

I still have not resolved this problem. I have dug through the wiring and have found no shorts. Also, my low fuel light does not work Its all just a mess and driving me nuts.

 

Go to the CPU and depin the wire for the Hazards. It's a Light Green wire in color.

 

this sounds easy enough, but what should i expect to happen when i depin it?

 

By doing this your figuring out which half of the Hazard circuit is bad.

It's either in the switch itself or the CPU, one or the other.

If you depin the wire at the CPU and can now get turn signals, then the problem lies in the CPU.

If the problem persists, the problem lies in the switch itself.

I'd think it's a CPU problem myself but wouldn't know unless you did the above.

 

Well i depinned that wire at the cpu nothing changed. The blinkers still worked normally, when i hit a bump with the right signal on it blew the hazard as before.

I know i depinned the correct wire.

 

Also, I changed the hazard switch with no luck.

Nothing in there has to do with Turn signals, but thanks

 

Just trying to help. I dont know much about these cars. I just aquire my first days ago. That was just a thread I ran across.

I can't even figure out how to get the exterion door handle off mine. Go figure!

 

Help is always appreciated.

So the next step in the process is trying to trace down the wires that run out of the cpu to the front/rear right turn signals. I want to depin the right turnsignal wires from the cpu and see if the problem still happens.

 

According to the wiring diagram it is a G/W wire on the cpu plug for the right lights. I am going to depin that and see if it still blows fuses when the right signal is triggered

 

the turn signals are pretty much fixed. I splice into the green/white wire from the cpu and ran new wires to the front right turn signal and the back right turn signal. Only wire I have not ran yet is up to the indicator. Not real sure where that wire is or how I should run it.

 

To me that would have indicated that the problem did not lie in the hazard switch itself or its wiring and the problem would lie in the either the CPU or the wires b/t the CPU and the signal lights. Disconnecting the r/h and then the l/h signal lights at the lights themselves might have been the next step or depinning the l/h and then the r/h signal lights at the CPU would have been the next step to see which run of wires is the bad actor.

Not real likely it's the indicators in the dash. you could disconnect those two if the problem persists.

 

That is what i did, when i disconnected the right signal lights from the cpu the fuse blowing stopped. so i just rewired that. The only part i have not rewired is the dash indicator light because i have not figured out which wire goes to the cluster yet.

As always hailers you are a huge help.

 

The wire to the turn indicator is still GW. But what the deal is, is that according to the diagram above, the GW wire has a couple of other GW spliced to it INSIDE the harness wrapping. Hard to say just how far away from the CPU the other GW wires are spliced to it.

Plus the GW for the indicator on the dash has two connectors it goes thru. One connector is at the gauge cluster and has a ref designator CR-01 and prior to that is a connector that has a ref designator of FC-01. I dont' right off know where that connector is. The online diagrams have a picuture showing the approx location of it inside the car.

Your problem seems to be fixed so I'd leave it alone for now. Gone
