As often as not it's the switch. Swap the left/right switches and see if the problem changes sides.
If it *is* the switch then you might be able to repair the old one. Often they can be carefully pried open and the contacts cleaned. Or sometimes you can spray electrical contact cleaner into the innards of the switch and bring 'em back to life.
If the switch *must* be replaced be selective in what you buy. Buy a genuine Lucas if you can. Some vendors sell a rather chintzy aftermarket replacement which is even worse than the originals and doesn't last. This makes repairing the old one, if possible, a more attractive solution IMHO
