I have a Mk 3 Astra 2.0 Sport Estate fitted with a tow bar.
I put the trailer plug on the wrong way. It wasn't going in all the way but I put that down to it being stiff and drove off anyway. As soon as I hit the brakes I got a brake light message on the console. I've come back and started checking fuses and bulbs.
The bulbs are fine.
I can't see anything wrong with the fuses(well those under the dashboard anyway)
Left and right indicator do not click inside the car nor blink outside the car.
Hazards on the other hand work perfectly well.
Brake lights won't come at all.
Any ideas, please!!!!
