I'm having problems with my XK's aircon and while groping about the InterWeb found these people
- JaguarClimateControl.com
I couldn't see a reference to them in the S type FAQs. If they've been mentioned before then sorry..Otherwise it might help someone (not me unfortunately)

Thanks Steve.
They have been mentioned several times and used to post here on the various heating/cooling threads, I haven't seen them for some time.
A reminder never harms.

Thanks for the feedback, Norri. I thought someone must have picked them up but you never know.
Back to trying to see ANYTHING in the XK engine compartment. Oh for the sixties and my 2L Vitesse - open the bonnet, sit on the front wheel and get at everything......
