Central locking

[xjokux]

My 1995 rvr locking has recently started playing up in this winter season.

Driver side has a epileptic fit only unlocking the car. It's not a consistent issues but is becoming more frequently.

Usually it stops once the car is on. I know the alternator bushes needs a clean/replace.

I have taken off the door trim but happens to be working fine.

Would this be related to the alternator or the locking motor itself?

It's likely to be dirty contacts in the central lock mechanism, but without seeing it myself it's hard to diagnose.

I've seen locks do this before, it's only ever the controlling locks that do it as well.....weird.
