On the 98 Elite, the outside temp display comes up blank when I cycle through the dash display, which the previous owner said just needed a new sensor to fix. Not un-coincidentally (from a few searches here) it turns out, there's no life in the aircon. ???
After looking at the maintenance guides, it's suggested the sensor is behind the bumper on the nearside. Rummaging around this evening it looks like the car's taken a front-end hit at some point and everything's been lashed back together sharpish. There's no sign of the sensor, but I did find this connector dangling down near the horns - does it ring any bells with anyone ?

You'll notice the signal wire from the connector is cut, so it wouldn't have done anything anyway, but if it's the right wires I could try putting a variable resistor across it to see if I can trigger a reading on the dash...

That's the SAI pump plug. Look for sensor clipped in underside of bumper, in that area

I'll have another look tomorrow evening. The SAI pump probably wants power as well, while I'm there. Never knew Vauxhall used so many wood screws to hold the bumper on... ;D

SAI can stay unplugged, as it's just for tree-hugging purposes. You may find, after plugging it in, that there's a annoying knockknockknock or other noise coming from the engine bay, the SAI pumps often fail over many years, the usual thing is to remove them completely. :)
