Hi, my heater blower has stopped working on my 2005 x type diesel estate. The switch already had 2 settings not working when I bought it a year ago then 3/4 months ago lost another. Now it has stopped altogether. Took fan out and connected it to a battery and it worked, albeit a bit noisy so bought a new one. Still not working. Swapped a relay over, same. Would it be the resistor I need to replace. It is a 6 pin plug one. Approx £45 from Barretts Jaguar. Or would it be switch. Haven't got a tester and don't know how to use one anyhow. Ideas would be welcome. Also is that a good price
