Hi you lot,
Just to finish off this thread . . .
Air Con issues: The Condenser on the air con system is leaking. I shot round to Halfords (I know

. . but they were doing a free air con system check

) They gassed it and the guy apparently froze his steel toecap. So I'm going to be sourcing a new condenser unit in the new year.
Fog Lights: I eventually got round to looking at the problem of fitting them. I rang Steve at Heathrow, and he was really great. He expalined the system and flogged me a new piece of wiring loom. The loom from the outside temp sensor to the first main loom plug is replaced with feeds for the fogs and the sensor.
A trip to Vauxhall got the screws and the plastic plugs they screw into for a couple of quid.
Basically I fitted the whole lot on Saturday morning, including changing the main light switch with the extra foglight button (this is where the relay is housed), and . . . nothing

Then I remembered Rob G's post . . the fuse ! D'oh. One 20 Amp fuse later brilliant kerb lighting !
Now all I need to do is adjust the flamin' things
Many thanks to you all for the help . . no doubt "I'll be back"
All the best,
Happy Christmas (Bah humbug)
