Hi people. I'm new to theses meganes and one day I was driving and noticed my brake lights have stopped working. I have replaced the brake light switch and changed the bulbs and fuses. But no joy. Wondering if any one can help me as Need the car back on the road asap. Thanks
There is a Major electrical connection box under the passenger seat I think it called the Body Control Module or BCM. This feeds all electrical signals to the rear of the vehicle. Unfortunately due to the design It can be subject to corrosion and can be the cause of all sorts of "strange" electrical wierdness. Removal and repair will need the removal of the passenger seat so you have to take precautions with Air bags Etc. Search for body control module or bcm should find you step by step (you can sometimes check the wiring before and after the module to confirm a fault before starting the procedure
Thank you mate. I have a look today. It's weird it happened when it was raining so I was rain must of got somewhere. Fingers crossed that's the problem. I do some googling now
With mine the fault meant the tailgate lock would not open, (the alternate route via the rear seats was available though ). I'd suggest you check the water ingress on the passenger door (water in door pockets, floor bins, damp carpets Etc) if you have this sort of thing check and clear the scuttle drains ( there are a few threads here on methods )
This is my first megane and I do love it. Until it rained. I have taken out the fuse box in the engine and cleaned it. Sorry one other thing the stop fuse in the glove box when I replace it the minute I touch the brake pedal it blows straight away. I'm just getting a little stressed. Thank you for your help very appreciated
Brake fuses, or any other fuses, blowing immediately that current is applied is a common symptom of a wiring fault (often a Short of the Positive cable to the body earth), this has always been the case, but with modern car designs, can also be due to an electronics fault The first fault is a case of tracing the cable with a meter to find the break and then re-connecting / insulating. The second is often best left to a specialist (it's much less likely). Shorts can also be due to damaged / dirty / wet connections so worth checking these ( Hair dryer is a useful tool for dealing with water ingress ( in your case try to direct some warm air behind / through the cabin fuse box ))
