Hi guys
I have bought a different micro-switch for my boot lock because I am only able to open it with the remote.

I plugged it in before taking the old one off. Good job I did because I get nothing, no lock noise when I push the switch, so I guess this one is not working as well.

Am I missing something here, do I need to do something else to get it to work?
If my original switch isn't the problem, any ideas what else it could be, because like I said it works fine with the remote.

cheers

edit:
Is there anyway I can check my switch before buying another one again?

Is the interior button working?  Any other locking issues?

Usually the switch if its just the boot switch issue but other locking problems could point to the drivers door lock
module being faulty.

Cheers thats pretty much confirmed what I was thinking.  

The interior switch doesn't work either but I have no other issues with my locks at all, so that would suggest this one is faulty as well then.
Any ideas on how I can test it before I take it back?

Use a multimeter
Resistance shows when switch works
DC volts for the circuit.

Connect meter to the Blue/black wire of the boot switch and to earth.
Should be only around 2V (not 12v).  If 0V, unplug the dash switch and try again.
If still 0V then the wire is being earthed somewhere, look for damage to the loom in the boot area, it's a matter of finding it!

Discconnect the boot switch, Does the interior button start to work?

[pcs333]

Thanks guys for the tips and info. Much appreciated  

I will test with my multimeter tomorrow and also try the boot switch. I know it doesn`t work when the switch is plugged in.

Let you know how it goes.

Thanks for the info.

I have tested as described and I am getting 0.15V from the blue/black wire, but it goes upto 0.7v for about 30secs after using the remote to activate the boot lock and then back down to 0.15v.
On the switched side of the micro-switch I am getting a reading of 0v, so i guess the switch is getting some power.
Also the dashboard switch still doesn't work with the micro-switch unplugged.
I have ordered another new switch so hopefully this one will work.

A slight error, I was relying on memory.
Mine has 0.8V at the dash switch, blue/black and yellow/black wires share the same terminal.
Voltage does not change when the remote is used but obviously the switch earths it.

Hope that helps with the fault finding!

Thanks for that.
When I get the new switch I shall do some more testing if it doesn't work.

Right new switch didn't work either  

I have tested the voltage at my dashboard switch and it is about 0.5v, the same as the boot switch.

I`m stuck now, are there any fuses I can try? I can't see any.
If there are no fuses or relays I can test I guess I will need to try a new drivers door lock, is that correct?

Cheers Guys

Where is the drivers door lock module guys?

Thanks for the guide, most of the pics associated with the actual locking motor are missing though.

Is this what I need http://cgi.ebay.co.u...64#ht_500wt_949 , or is there a seperate module as well?

[Master-of-none]

Yes that is the lock/motor/module

But, before spending £25+ you could try this:
Others have found damage where the cables flex when joining the tailgate it may be worth peeling this back to look.
otherwise the usual disclaimer applies - assumes you can cut and safely repair a piece of wire without destroying the car!

Carefully cut or remove the black/blue wire from the rear of the dash switch, so that just the yellow/black remains
(leave a tail so it can be rejoined/replaced)
Check the volts & dash switch action, if it works then you do have an earth fault in the wiring towards the boot.

I checked today just by unplugging the dash switch and checking the voltage on the black/blue wire. It was 0.5v which is similar as what the boot switch is getting.
Does this not confirm that the loom is ok?

Thanks for your help  

[Master-of-none]

My suggestion would isolate the (possibly) damaged part of the loom and confirm that the dash switch works.

Thanks I understand what you're saying now, I was slightly confused there for a minute.  

I shall try that, thanks again.

No the dash switch is not working either after trying master-of-none's suggestion.

Just ordered another door lock from ebay. fingers crossed it works.

[oldsierra fan]

My boot release switch never used to work, or the handle on the tailgate, when i replaced the drivers master lock it started working and still does .. hope you get yours sorted.

Thanks m8

I did get one from ebay and it arrived with the cable connector broken off so I couldn't use it.

Ironically it did sort my problems out, because I plugged it in to test, but obviously I can't use it.
