A good pictorial explanation can be found in the Volvo service 'green' books. A PDF copy can be found at https://volvoamazonpictures.se/wordp...rvice-manuals/ if you don't have a physical copy to hand.

Hi thanks for that.
So where does the sensitive coil on the heater valve sit, i have heard that from factory it was postioned inside the heater unit next to the matrix, or does it just sit in the cabin next to the valve.
Does this unit actually work in regards to regulating hot and cold, mine i know is knackered so the only control i have is via hot and cold lever. so when on cold its hot and when on hot it is really hot!
