L322 Heater blower

SuffolkCraftsmen · Jan 20, 2020

My heater blower stopped blowing this morning. Checked the dishes in the glove box and they are all ok, all the lights come on ok like it’s working. The diagnostics don’t throw up any faults so I’m guessing it’s the blower motor? Does anyone know what’s the easy way to get to it?

Auto correct! That’s fuses not dishes in the glove box!

I was curious as that was not a spec I'd heard of before...dishwasher.

Final stage resistor perhaps?

Yes I would try that first, could well be. A lot easier and cheaper than the blower motor to change.

I changed my fan a few years back, it was squeaking and making some random noises and on its last legs.
There is a good guide on it here...... http://www.fullfatrr.com/forum/topic14961-45.html

As above the FSR is very common....change it before it kills your battery too.

Final Stage Resistor - FSR, thats all very well but; where is it and how do I change it?

Devilish · Jan 20, 2020

As already ,said, bound to be the FSR

No! Im going to bed but I will probably open her up in the morning to have a look and if wiggling the wires doesnt fix it ill order the part.

Of course if the FSR doesnt fix it then it could be the motor in which case the easy way to get to it is dash top off then cut a hole in the plastic above it ( I kid you not, check it out think its on youtube somewhere) then gaffa tape it back together, friend of mine had the same sort of thing on his J----, his J----, no just cant say that word !

On the later l322, some things have more than one fuse (one for the control circuit, one for the power)
Check there isn't another fuse in the underbonnet fuse box for example.

The previous owner of mine had gone to not very great length to lash in a horn button because steering wheel buttons didn't work, one new fuse was all it needed.
Depending on year, there are some wiring diagrams in the tech archive in my Dropbox (called something like "rave microcat and other range rover stuff"

And this morning it just worked. Ffs

just as well as it’s -5 out here this morning!

SuffolkCraftsmen · Jan 21, 2020

Update. At lunch time it didn’t work!

Saint.V8 · Jan 21, 2020

If it is intermittent, odds on its the FSR.

SuffolkCraftsmen · Jan 27, 2020

Well..... I replaced the FSR, the blower worked for a couple of days but was not working as I would have expected, then this evening the dash board cought fire and wrote the car off.

Problem solved.
