DRIVER SIDE DOOR SWITCH

[aearch]

as these are nla and tend to break \ here is the replacement
it is exactly the same . you just take off the rubber
and cut the extra part of the button off with diagonals. and file smooth

$45? - No thanks!

These are $3:

The driver side is different, it needs the second prong for the window relay.

Cool thanks for clarifying. Definitely more expensive than the single prong one! $45 is still too much for a door switch though. Looks like they can be had for $20ish:

? Can you elucidate a bit more about the need for a second prong for the window relay. What's happening there?

Not on euro models.

i think this only applies to coupes with electric windows

I have leccy windows all round

I have a US model with electric windows. My door switch is missing. I haven't dug into it yet because the car will shortly be taken apart for rust repair but I'm wanting to get all the bits I'll need so I'm ready to go and not waiting for parts.
I was planning to add relays to the window motors to lessen the load on the switches and maybe speed things up as was suggested in an earlier post. I still don't get what the door switch might have to do with the windows.

Thanks for the help.

For the US at least it is a feature that lets you use the window before using ignition switch. Open the driver door and windows will operate. Also anti theft, can't insert a stick into car and hit one of the switches.

Same here. Euro with power windows front and rear. Confirmed single pin. Must be a US feature.

It's a later feature as well i think, my '72 does hot have these relays.

 

[mulberryworks]

Very interesting. I hadn't considered the anti-theft facet.
Thanks for the help. Great photo Mark.

The erudition of the members of this forum is beyond parallel.

Mine is a '73 built in '72. Would be interesting for a '74 euro car owner to check.

There is only one relay, if you push the button in you can hear it click. Steve, you can't open windows unless key is on?

May have been introduced when circuit breakers were added and motors changed:

CS 2213396
CSA 2231938
CSi 2264525
CS USA 2240634
CSA USA 2250501

No, I need the key. This is my plunger switch, is this what it should look like if I have the relay, and where should the relay be? I will check.

guys, i have a '71 2800cs (us spec car), and it has the same switch Steve has ... and has 2 separate wires. i do not have the window circuit breakers ... well i actually have them in the panel since i have a '74 telescoping steering column and the '74 trim panel ... they just aren't wired up.

 

[aearch]

one wire goes to the interior light and the other goes to the passenger side.
hence two wires which are always hot and the switch grounds it

 

[HB Chris]

Steve, yes that is how it looks. Relay is near steering column/firewall I think, will have to check.
