Door lock actuator

Just spent an afternoon stripping and rebuilding my freelander passenger front ns door to fit an alleged working actuator which I bought from a car dismantler. My door lock was working only to lock not unlock with the fob before I started. Well what I noticed in the part I got from the dealer was that it had eight pins on the connector whilst mine had only seven dont know if this makes a difference? Anyway I fitted it and tried it ! nothing absolutely nothing ! Was I ****ed off, is there something I am missing does this pin difference make a difference,does anything need to be rest or is it just a dud unit ? Help required asap.

This is looking bad lads ! no one has any idea's.

Have you tested it with a multimeter to see if currents going where it's supposed to? Locks are little feckers, got my tailgate seen to today. So far so good.

I would say the different number of pins would make quite a difference, to be honest.

Personally I wouldn't trust a 2nd hand unit. Get a new one. At least you know it will work, and will be right for your vehicle. As in, it will have the right connector on it

Yes you are right however 2 university graduations in a row with photographs dinners etc and one with three return flights to the main land from N.Ireland really eats at the linnings of the pockets ! so I will have to back burner it for a while but thanks anyway to all.
