My fan motor has packed in and the resistor has burnt out.
I've read the various threads on how to repair the motor and the resistor. However, none of them describe how to actually remove the motor from the vehicle.
I've removed the air intake from above the motor, but the motor seems to be secured within a sealed unit. I think it might be secured from the underside. Do I need to remove the entire unit, including the fuse box on top and cabling?
Help, please....

I had my motor out the other week to try to improve its running. You can remove it without taking the housing off, but you'll never get it back in again. I'll have to nip out in the morning to refresh my memory if this is not clear, but there are a few 10mm nuts to remove, disconnect the in-line 12v connector & gently remove the whole lot from the bulkhead. Note - there is a connector that passes thru the hole in the bulkhead where the housing attached - this is for the re-circulation flap motor - it will need to be disconnected before you can fully pull it away.
Turn the unit over, undo 3 screws & the rubber drain pipe & the motor/fan will come out. Undo nut on top of fan (probably rusty) & carefully remove fan from motor spindle. The next bit is tricky unless you are confident about this sort of stuff. I would recommend you make a scratch or mark to indicate which way round the bits go. Undo the 2 bolts that hold the motor together. CAREFULLY try to push the spindle into the motor so it pushes the rear of the motor assembly away. The idea is not to seperate the brushes inside the rear section from the main rotating part (armature). You will have to overcome the strength of the magnet to do this. Once apart, note where the brushes, springs & washers go. Carefully clean all the parts & bearings. The bearings should be self-lubricating, but I used a small drop of light oil for good measure. In true Haynes manual-style: re-assembly is the opposite of removal, but be careful to get the brushes in the right way round as they will have bedded in one direction. It would be worth a quick test before boxing it all back together again.
This is not a job for the faint-hearted: I wished I hadn't started, but had no choice but to stick it back together again. Best of luck

You can remove the fan unit from the bottom and put it back in - but I agree with SJ it is a bit fiddly - I found the secret was using a ratchet phillips screwdriver - as you will only be able to get one hand underneath the unit. There are only three screws if memory serves.
BTW after being smug about fixing my resistor pack and servicing the motor months ago - found it blew again on Monday. Had a look under the bonnet and drain plug was full of crap - so its worth checking.

Hi there
We've had our bongo for 'bout 4 weeks & then i noticed that the fan motor was not operating, i first checked the resistor with multi meter - which appeared to be OK, then moved onto the fan motor:
You can remove & refit (i found quite easily) the motor from beneath the duct. There are 3 crosshead screws (around the fan motor near to the 'edge' of the assembly), undo the 12v connector and ease out the motor & fan basket - it needs abit of wiggling!
Knowing the price of a new fan motor i decided it was worth dismantling,
after removing the 'fan' I undid the 2 screws holding bottom together - then the problem was clear - rusted up connectors & brushes ( the brushes were corroded and didn't spring forward on the windings etc) i just took it apart piece by piece, clean it all with sandpaper & reassembled - to my delight it now works as new on all speeds!!
Please note I take no responsibilty if you try this & cant get it back together/burn down ur bongo etc....
