Mk2 Hazard Switches are prone to stop holding in, making a piece of folded up paper a vital tool in Nova Mk2 ownership. lol
However, taking it apart and tweaking it to work correctly again is a simple (if fiddly) job.
You'll only need a small electrical screwdriver, and a pair of pliers (or two) to do this fix.
Remove the switch from your car.

You need to remove the switch fascia, a small screwdriver under the lip.

and a pull off the moulding.....:thumb:

The next step in to slowly prise the outer casing off the switch.
Insert your screwdriver into the gap between the two to lift the plastic over the small lugs

Do the same for the bottom two lugs and carefully push the switch backwards.

BE CAREFUL, THERE ARE TWO SPRINGS INSIDE.
With the switch apart you'll have the following three units.

The bit that is causing the switch not to latch is the metal rod, it will have bent slightly.
Remove this rod.

With your pliers, bend this rod straight or slightly bent towards the lugs.

Notice it's slightly bent down :(
That's the fix done, now time to put it back together.
Push the rod back into it's clip. (it will be a tight fit)

Then take the front half of the switch, locate the springs into their location on the front half of the switch, place the pins on the back of the switch into the centre of each spring and carefully push the two halves together.
You need to ensure the metal contacts on the front half are inside of all the back outer contacts.
When you push the two halves together it should click together.

If it doesn't, you need to bend the rod slightly more.
Take this assembly and slide the outer casing over the front it, to locate on the four lugs at the back.
You should end up with this.

A press on the front of the switch.....

Sorted
Refit the front of the switch and fit it back in your dash
(Keep the folded paper, just in case)
