Ignition Switch

Could anyone tell me how to replace the ignition switch control (This is the unit that mounts behind the key) of my Porsche 964?

Thx for the help

They unscrew if that's what you are asking. Not sure on a 964 if you have to pull the whole thing to get to it.

If we are talking about the same part, it is mounted with bolts that have a break off head to reduce theft. You need to grind the remaining part of the bolts off to remove.

Are you talking about the electrical switch or the key lock? The lock is bolted in with break away screws but the actual electrical switch behind the lock mechanism is held in place by two simple screws. Changing the switch is actually very easy once you get to it behind the dash. you need to remove a couple of pieces and take the left vent grille off to get to the switch - you also need some band aids

Hello Cjoenck,

It's the electrical switch. I have to pull off the wire connector from that switch.
But then, i think the bottom screw is easy? , but the top screw
how to get there ? Do i need a special tool, is there a secret to get to that screw?

Grtz
Rob

you take the whole assembly out and then swap the switch.

Take out the seat:


Lay on your back with you head under the dash.
Remove this module:

Now you can see and reach the switch.

Now unplug the harness from the back of the switch. The switch will look like this:
There's a hole in the knee bolster below the switch. Put a piece of tape over it so you don't lose the screw from the switch in it. Now take the two screws out and remove the switch.

When you look at the back of the switch you will notice that it will only install in one orientation.
Installation is the reverse of removal.
To John Walker's point, it's usually not the switch that goes bad; it's the tumbler mechanism getting contaminated from the key and wearing out that causes the problems. Try shooting some WD-40 into it and then stick the key in, pull it out and wipe it off about 30 times to get the debris out of it. This technique improved the function of my tumbler.

Does the electrical connector just pull straight off?

I'm replacing the electric part of the ignition switch and am afraid I'll mess up the connector. Does it just pull straight back off of the pins?

Yes .. I used a plastic trim removing tool and worked one side, then the other until it let go.
