I am looking for a Klima relay for my 1991 SDL.
The part number is 003-545-26-05.

I would even consider purchasing someone's broken relay (this is for a bit of an experiment, long story)

Please PM me if you have one.

FWIW the 86/87 300SDL use the same relay.

Thanks. I've been having a heck of a time finding out what I can and can't use.

I'm really only concerned with the kickdown function. I've bypassed the rest of the relay with an ice cube relay.

For the trans or the AC cutout?

For the transmission.
I got rid of my Klima relay last year (replaced it with an ice cube relay) and with it lost the transmission kickdown function.

I think you just need to send 12V to the proper pin. I could be talked into studying the diagram if you don't have access to one.

I'd be really grateful if you could look. I can't find a wiring diagram or an electrical manual PDF for my car. I'm fairly handy with electrical stuff in cars- heck, I own an older Range Rover- but it's a lot harder without manuals.
