Can anyone help! I have a discovery 2 td5 2001 (pre facefift), my heaters have packed up in the cabin. They were working on setting 3 and 4 unroll last week. I was told it was the resistor pack that had gone, however I looked up one for her and can't find it? Plenty of motors though. Is it build into the motor unlike the facelifts where it's a pack separate? Or is it part of the switch on the dash? Thanks for reading, Dawn.
