Heater blower will only work on max. I have read other articles on this where people have replaced the resistor and all was well. I too went down this road replaced the resistor but still the same problem. A little more playing with the multimeter and it turns out it was the little aluminium capacitor on the reverse side of the resistor. A quick call to RS solutions a quick solder job and all works again. Landrover OEM replacement £140, capacitor £0.18p
Hope this helps anyone one with the same issue.

Love it!
Well done!

Why can no one make decent capacitors? This seems to be at the root of so many electronic breakdowns. Not just in cars.
I have had it in dishwashers and domestic thermostats.:(

Respect for your work but you keep telling about a "resistor" while on then D2 it's about a power transistor in this case unless it's the very primary spec with he D1 matrix.:rolleyes:

You are probably right on the correct terminology, I have only called it a resistor as all the threads and info I have read about this have used the same term.
In plain terms it's the little round thing in the middle of all the cooling fins. 👍

The electrolytic capacitors can dry out, especially if they are near a heat source, like in the old telly's for example. There's a variety of solid dielectrics such as tantalum or 'X7R', and some of these are better in certain applications than others. That said, the one Dreckly has just fitted will probably see the car out!
 
OK, so the saga continues.......another capacitor down. As it turns out, the cheeky little rascals at Landover have hidden a little 2amp fuse on the underside of the black plastic moulding, which is only accessible by de soldering the resistor (the little round thing with 2 prongs). i have now soldered a new fuse in place and all is well. Everyday is a school day :p
 
IMO you should have replaced the transistor too cos it might have a resistive/intermittent "leak" inside hence it blew the capacitor and the fuse, the original is Toshiba 2SD1460 hard to find in Europe but there are equivalents for it like for example MJ11016

Thank you for that info, I did mange to track down some 2SD1460 from China, however whether they are genuine is another issue.
Thank you for the equivalent too ill make a note of that. Its all working as it should now, so fingers crossed it stays like that. 👍
