Just a thought that part may be component protected so replacement isn't a simple case of swap out/in.

Are there any obvious clips on the new part? Sorry don't know how to fit it but if it doesn't screw in behind the dash I'd assume there is a release clip. I'm sure someone else will be along to advise. Let me know how you get on still no heaters either and the weather is getting colder!

How have you got on Dan? Got exactly the same problem on mine and the garage recommended exactly the same remedy. Has flushing it worked?
