Just recently the steering wheel has not moved into it's set position when the key is put in the ignition. It will jog in increments on the switch and then operate normally, and all is well for a time. My question is, could this be a relay?. And if so where is it located, and what is the part number if it is the fault. I can here it clicking. Many thanks. Anthony.

 

Mine does this too. There is at least one detailed thread on fixing this, have a search. It is not a relay. its a mechanical issue and is a bit annoying to get at/fix, which is why I havent done it yet. I think working under the steering column is one of the worst positions to be in working on a car lol

 

I did this repair a few years ago and I'm pretty mechanically inept. It was a pain but doable. Here's the link. Check it out. Lots of good advice and where to get the parts.

In your case though it wasn't working at all. In the OP's case it's the usual "does work but keeps stopping", which can be fixed by snipping a wire:-

Snipped the wire yesterday and voila it worked. Thank you forum
