| A simple cheap fix for weak Central
Locking Motors on FTO's
Introduction
How many of you guys (or girls) have central
locking that does not always work? My FTO had a very weak drivers side
lock. (200bhp and they can't get an electric motor to open the door!!)
So far I've cleaned the central door lock mechanism twice. The first time
I pulled the little motor apart that drives the whole thing and cleaned
the sensor switch etc, it lasted two months. The second time I cleaned
all the moving parts of the door lock to remove all the old grease and
lubricated it with thin silicon oil. It lasted two weeks!!! I got bored
with this and came up with the following solution.
Parts Required
A Door Lock Motor from Maplin.
There are two types, a 5 wire (Order code YD78K £8.99) and a 2 wire
version (Order code YD79L £7.99). Either will work all you need is
the 2 wires but the 5 wire version has a built in 2 way switch (May be
useful if you want to use it to fold in your mirrors or something)
A couple of Lucas spade connectors (Halfords
or Maplin)
DO THIS AT YOUR OWN RISK
There are a couple of things I'm not sure
about. What effect it will have on the Mitsubishi Door Controller (Under
the dash on the driver's side). How long will the Maplin Door Lock Motor
last. The Maplin Door Lock Motor moves about a lot when it operates, is
it going to fall off. (Time will tell)
How to Install
-
Disconnect the battery. (It's up to you!!!
Reset your ECU/Gearbox or blow a few things up)
-
The first thing to do is to remove
the interior door panel.
-
Disconnect the cable from the bottom of the
original central door lock assembly.
-
Remove the BLUE/RED and BLUE/BLACK from the
connector housing, use a very small screwdriver to release the catch inside
between the metal connector and the plastic plug housing. This is very
fiddly.
-
Now reconnect the connector (with the two
remaining wires) into the original central door lock assembly so it can
use the original central door lock position sensor. (Providing this is
not the part that’s faulty - normally it's the motor that gets weak)
-
Fit the Maplin Door Lock Motor as per the
photo below.
just make sure that the window does not hit the new Door Lock Motor. You
will need to drill 2 small holes in the metal inner panel and bend the
connecting rod to suit. DO NOT fully tighten the adapter that fixes the
new rod to the original connector rod, this will need adjusting once it's
all working.
-
Connect the BLUE/RED to the GREEN wire and
the BLUE/BLACK to the BLUE wire on the Maplin Door Lock Motor. You will
have to solder on some new connectors onto the Maplin Door Lock Motor as
they are the wrong type.
-
Now connect that battery. Look for smoke!!
-
Now operate the locks with the remote control.
You will have to operate the door lock manually at the same time to keep
the original central door lock position sensor in sync, if not the locks
will do some funny things like unlock and lock straight away.
-
Take note of where the adapter that fixes
the new rod to the original connector rod, adjust and fix to suit.
