Got a problem today, whilst pushing the brakes pedal theres no relay click sound hence no chance to move the handle from P to any of R, D, N. When I start the engine, pull out the key and put it in the emergency kinda socket right beside the gearbox handle it switches no problem thus I could drive and reverse.What could it be? is there any fuse or something for that relay???Could it be fixed by myself or should to bring it down to a garage???
