Hi All
My wifes Range Rover is a lovely L322 year 2005, 3.0 Diesel BMW Diesel.
So as we know the L322 likes to eat batteries. I replaced the battery about 1 year ago with a good quality VARTA Battery and all has been okay until the recent cold weather and with Covid lock down not being able to go anywhere.
I use a trickle charger, but sometimes this still is not quite enough therefore I have ordered ordered another battery YBX5019 Yuasa Silver High Performance Car Battery 12V 100Ah HSB019, I think my current VARTA battery is okay still and will keep as a spare charged up in the garage.
Also I have read through the posts on causes of battery drains and most seem to point to the infamous:
HEATER BLOWER FAN RESISTOR MOTOR REGULATOR HEDGEHOG .
Therefore I have also ordered one of these but I have a question that I would like some advice on.
The reason I am looking at changing the resistor is that I noticed when I was sitting on the car without the key in the ignition, I could hear what I think was part of the heater matrix system coming on and off, its like a faint low hum. I therefore surmise that this could be caused by a faulty heater fan resistor hence why I thought to change, would you agree?
Thank in advance
