If you mean the short 3 position stalk on the steering column - then yes, I've been through at least 4 on 3 110's!!
The contacts just let go after a while - maybe I'm too rough with them.....
Buy the right one - yours will come with loose ends on the wires needing spade/bullet connectors. The later models have a nylon oush fit block and cost about £40 from memory :shock:
Steering column covers need to be both undone (screws under bottom section and 4 recessed in top section. Real pain to fiddle over the key assembly (make sure the key is out!). Putting back together is worse just finding the screw hole underneath. Contorionist and use a feeler to locate the threaded hole first before putting the screw in worked ok.
If its not this then good luck anyway......! Age
