Berlingo B9 van 59 plate heater problem

[Jackkeleher]

Hi guys 

B9 van 59 plate 

Heater works on number 2 but outputs the speed of 4 or nothing 
1-3-4 don’t work I changed the block relay under the glove box to no improvement 
I see a resistor block is available to buy but don’t n ow how to locate or if this would help

Any advice really appreciated

Thanks Jack

The resistor pack is inside the blower fan casing next to the accelerator pedal.
You need to get your head in the driver's footwell and you can see it in the corner. It's a bit fiddly.
Remove connector, One fixing, Slide resistor pack to one side and remove...

I replaced just the thermal fuse on my heater resistor pack when I had the blower (all or nothing) problem.
I crimped the thermal fuse in place. Still working 6 months later.

This is the compatible resistor pack I found if you just want to replace the whole thing.
