Indicators not self cancelling and horn not working

It is a Renault and it is old! :>D

This is a known issue and is mention in the link. I would take it to a good auto-electrician and connect it to a quality scan tool computer and test the alarm sensors and the bonnet switch. Why the alarm sets itself is even more of a puzzle!.

Hi, my lefthand indicator light is not functioning propely on my Renault megane scenic 1.6. 2001 model. there is that flicker sound when I turn it on and it ticks very fast and nothing flashes on the dash and nothing on the external lights as well. It also does the same thing on the hazards but the right hand side works perfect. please help. EDDIE

Your turn signal switch is most probably faulty. You will need to replace it. Please, check the videos below. The first video shows a similar problem on a Renault Clio. The second one shows the operations to replace the turn signal switch. I think that the operations are quite similar in most modern cars. Good luck!

Check the bulbs in the back lights as i suspect you have a wrong bulb fitted ,remove each bulb in each cluster in turn and look in the bulb holder as i think that you may have a single pole bulb in a double pole bulb holder ,if this checks out ok then check the earth on each rear light cluster as a non earth connection could also cause this problem,but i suspect a incorrect bulb in the wrong holder

Possible tdc/crank sensor. this can cause the car to not start and cut out

push the stork in towards the dash now try it if this works change the stork

I had the same problem. Horn not working and indicators not self cancelling.
After removing the steering wheel I found that the central two pronged collet, that engages with the steering wheel and drives the horn contact slipring and indicator cancellation, had worn down its prongs. this had caused the horn wires to stop rotating and they had been snapped by the motion of the steering wheel.
the ideal solution would be to replace the collet and horn wires but I managed to repair both
