Astra Mk2 Central Locking Driver's Door

[keithywoowoos]

Hi...

I'm 99% way through fitting a remote start alarm with central locking control to my Mk2 Astra. All good so far except I have sussed that there is no motor in the drivers door and read on here i need to fit one. Is it possible just to fit one from a passenger door? I've read that fitting a cavalier tailgate motor will keep the key control to the system working. Any idea what model Cavalier i need to get one off? Any tips or suggestions greatly appreciated!!

Thanks for your help guys... forums are the saviour of my life!

The thing is, the passenger door has a motor but no switch! (Someone at GM was desperate to save 0.09p per car on central locking)

Any mk3 Cav boot locking motor will do the trick. Had to do it a couple of times myself.

or a universal one off ebay i got the three wire one and it worked perfect

Thanks guys... That's real helpful. Task now is to find one! Had no idea they would be so hard to get hold of! Guess I'm off to a couple of breakers tomorrow!

So after ringing about every breakers I know, the cavi lock just isn't about, unless I wanna pay £75 for a new one... Which I don't!! :-) how do the universal ones work then? Do I need a specific type? I've seen some 5 wire ones on eBay but I'm not sure about connecting it to the current system. Any suggestions?

So I found a scrappy with a cavi... Drove over and bought the tailgate motor... Fitting it to my drivers door and... Works exactly the same as the one already fitted. Pops the locks with the key but won't pop with the remote. Came to conclusion that the motor was duff and returned it. Did I do anything wrong? Just did a straight swap. No other motor arounds :-(

Should just plug and play.

Had a dig through one of my spares boxes and have a known good mk3 cav tailgate lock motor here. £10 posted if you want. Part number is 90274241 if you want to look elsewhere.

Just checking: how many wires does your drivers door c/l unit have going to it?

[keithywoowoos]

5 wires mate... Checked it against the input for the controller and matches up. Rest of the system pops with the remote, just not the drivers door.

[keithywoowoos]

That's great mate... I'll have that off ya please. How you want paying?

[BigDave1979]

Sent you a PM!

[neilb1798]

if you are fitting after market alarm you need to remove it from the relay on tyhe car central locking and use the alarm box for the open and close

[keithywoowoos]

Could you tell me more about the relay mate? I've not been told this before and could be why the last cavi motor didn't work!!

[keithywoowoos]

FINALLY CRACKED IT!!
It would seem that the wires running the drivers lock with a bit dodgy as the passed through the plug in the door. Have spliced from c/l contoller and fed to lock Merck and boom... Instant central locking!!
Thanks for all your help guys!!

Glad you got it working.
