problem with turn indicators

I have a problem with the indicators which I can't fathom. I'd be grateful for any ideas or a solution as I've been battling for two days on this.

When I have the ignition on and indicate, neither left or right indicators flash, but I do get a steady green light on the dash.

When I put the crash flash on, with or without the ignition on all four indicator lights and the green light on the dash flash. Also the bulb in the illuminated crashflash switch works.

When the ignition is off  and I put the left or right indicator on,  the appropriate front and rear sidelights are illuminated.

I have just renewed all the earth points on the car as shown in the Haynes manual

 

There are 2 fuses in the turns.  A low numbered one for the Hazards f4, and a higher numbered one f19 for the turns.

On the back of the hazard switch there is a single bare Spad connector (thin) that if you short it to ground it takes out the higher numbered fuse.  When that fuse goes the lamp but glows. And you can short it on when you put it back in, or have the bare wire dangling about as you work on something else… To quote the immortal Forrest Gump "It Happens!" at the end of that scene you see a t-shirt with this on it .

To fix it from happening again, take some heat shrink and insulate that connector.


 

What a complete star you are - but not quite what you or I expected.

I checked the fuses and found a total of EIGHT blown fuses on the board. So I have a few hours trying to work out what is going on and individually check the circuits…What a nightmare.
However if you hadn't suggested this solution I would not have checked all the other fuses as well, until I have checked it all there's no point in me trying to fault find any particular facet.

I did buy this heap of junk as a project, it's providing me with that O.K.

There's so many cut and twisted together wires on the dashboard it's not true and that was after taking an aftermarket alarm system out. Thanks again.

That's like saying that marble statue of David by Michelangelo was just a hunk of stone.  

It only is going to get better with age and hard work.

I feel that any much older with this wonderful car and I'll be dead

LOL!

Aha some kind person had taken the blue/black wire off the switch, put two tap in connectors on and dropped it into the bottom of the  heater controls. Refitted it, took the tapins off, sleeved the wire where the insulation has been ripped off..jobs a goodun.

Next job is to find why the fan switch isn't doing anything

THe fan switch  switches 12V between the different parts of the resistor.  

Check your molex (White Nylon ok may be yellow now )
connector on the left side of the heater box there are 4 0r 5 wires depending on the speed as in 3 or 4 speed.  Take it apart and look to verify that the ground wire isn't toasted. That ground wire allows all speeds to work, or not.  I have had 3 Cabriolets and all of them had a toasted Ground wire.  I spliced around it with a insulated Crimp connection straight to a new poin on the inner firewall.



 

Mmm, seems that the motor is seized, from the noise it is making. I'll strip it down tomorrow

Yep, stripped the motor and gearbox down, out some fresh grease in and oiled the motor bearings, screwed the switch contact plate back with stainless self tappers. All works fine
