So I replaced the CPU and wiper/hazard switch, and still when I put the hazard fuse they just flash like they're on.
When I push the hazard button they flash double speed, but never turn off.

I'm just trying to get my blinkers to work... Any ideas ?

 

sometimes the wrong blinker bulbs can cause this too. did you change out the bulbs?

 

Did you replace the parts mentioned with known good units?

Other than that, maybe a short in the system? Any wiring been modified on it?

 

I replaced everything from my turbo parts car everything worked fine. All bulbs are new as well
It most likely has a short
Not sure where to start tho.
It had a pos jumper cable touch the neg side. That's what's caused all this in the first place

 

Don't worry. They sell it here. Blinker Fluid - $18.95 : KaleCoAuto.com, Your home for the rare, unusual, and hard to find auto parts.

 

Some NA and Turbo wiring, pins, and plugs are different. I'm thinking you may have constant ign. on (+) due to this...not thinking a short as much of a possibility now.

PM forum member "Satch". Look at electrical issue threads and see how posts often and detailed advice. Those members are more in the know than I am.

 

Hmm I'll check into that. I have the fsm for both

The CPU and the she itch cluster had the same part numbers but who knows

 

do they stop blinking when you turn the wipers on high?

 

Nope but they don't flash faster when the wipers are on.

I'm bout to give up and swap to my spare chassis. But no garage bleh

 

it isn't a convertible i hope, the switches are different between a coupe and vert since the vert has a convertible top switch in that location instead.

 

Naw 86 gxl
CPU and switches from a 86 turboII ( steel hood

 

same symptoms as the old switch?

the new switch also came from a series 4?

 

try disconnecting turn cancel connector F-16 at the base of the steering column

8 position connector all wires are green, one is light green. the cancel mechanism may have been damaged by a faulty steering wheel install, which could be preventing both turn signals from canceling.

 

Pull the 15 amp Turn fuse and then plug in the Hazard fuse and see if that changes anything.

 

Tried em and still not any change. I think I have to bust out the fsm an start checking wires

 

When the Light Green wire (CPU) has a ground on it the flasher unit will activate. The hazard switch button is what causes the ground to occur on the Light Green wire. If the button was in the off position then the wire would not have a ground on it. And if the indicator lights in the gauge cluster were bad perhaps that could cause the overly quick flashing.
