Central locking hazard lights

Dempo1

Forgive me if asked before. I've a clio 2009, for some inexplicable reason the Hazard lights are activating on their own, even when car parked up and engine off. The fault seems to be linked to the central locking system. I've noticed on the button you can activate central locking when in car, there's a red light on all the time. The issue seems only to happen when car parked up and engine off. I decided to disconnect battery tonight, have a better look tomorrow. Any ideas appreciated, thanks.

Where is the red light? On the key,is it? If so try taking the battery out of the key & see what happens.

Thanks, the red light on central locking button inside car, the key fob itself has no light, I've also tried a replacement battery in the Fob.

I'd not noticed the red light on before, only when clicking CL, now its on all the time.

Renault and electrical problems, sounds about right! Have a couple of electrical demons with my own

Had several cases where water has got into the interior, and on the Clio and scenic/megane family, there are a number of electrical plugs under the floor on the passenger side, and if they have become waterlogged, all sorts of strange things can happen as a result, including things like hazard lights operating when they should not, or worse.

It may be easier to take the seat out in order to get easier access to the plugs, as the carpet has to be pulled back to get at them. The big issue is that if it's not caught quickly, or the water is salty, the pins in the sockets and plugs can corrode, or in the worst case, with power on, the wires can become loose as a result of dissimilar metal electrolysis, and when the connector is moved, the wires will literally fall out of the pins without much strain, and to complicate the issue, all the wires in the smaller connector are the same colour, and on a recent Megane, there were no numbers on the wires to identify the circuit.

On the Clio, the water got in as a result of blocked scuttle drains, so the water rose in the scuttle, and came in through the heater. The Megane went into salty water, not over the door cills, but it got in through the floor drain plugs, and the large connector had to be cut out and the wires soldered, as did the smaller connector. The dash light up like a christmas tree, and it's taken a few hours to get everything dried out and stable again.
