How do you turn ON DRL on a 1997 940?

[black t top]

OK, so I've searched and searched and can't find any threads that cover this.

Basically on our recent purchase (a blackberry pearl 1997 940 estate to with our blue 1998 940 estate) there are no daytime running lights (DRL's).

I've tried the obvious 2 things, the headlight switch and the relay....I've swapped them out from our Blue car (which has working DRL's) into the new car, but still, no DRL's. I've gone over the wiring and can't see any obviously cut or messed with wires. The headlight assemblies and bulbs are the same on both cars too.......so is there some other way that they would have been turned off, if so, I want to put them back ON again!

Bit of car info:

It's a 1997 2.3 manual M90 Turbo. It was originally sold in Germany, to an army sergeant stationed there, then shipped back to the UK a year later when he came home, has every option going (inc cup holders) and every receipts from new, bill of sale ect. It is RHD.

Car started, light switch set to OFF (\).....front sidelights (small ones above the indicators) illuminate, dash illuminates, rear lights illuminate.

Car started, light switch set to PARKING LIGHTS (|).....same as above, no change.

Car started, light switch set to HEADLIGHTS (/).....headlights come on dipped beam as they should and operate as normal, parking lights above indicators stay illuminated as they should.

Anybody got any suggestions??
