The Mégane II Owners' Club

I have a 1998 Renault Megane Librete so probably not the best site to post but I was wondering if someone could help me with a lighting issue which occurred today. When I press the brake pedal the nearside flasher unit speeds up until the brake pedal is released at which time it reverts back to normal. I have checked both indicator bulbs and found them to be working, so I was wondering what else it could be.
Thanks

squeeze the connectors together on the rear nearside cluster....
