anyone had problems with their reverse lights working on and off,because of the reverse switch on the gearbox, I have to hold the gearstick in the reverse position hard for the reverse lights to come on,otherwise they dont work. is there a easy way to fix or replace the switch ? from underneath the car ,not only is the front drive shaft in the way of getting to it, but even if it wasnt the spot where it is ,is near impossible to reach. i dont want to have to remove the whole gearbox just for a switch. any ideas?
