NO last resort, i could be something so simple, you could easily get robbed silly for a simple fix.

have you checked your fusebox to see if they are all ok ?,

dirty contact on the a/c button ?,

try to listen for any relays clicking etc when you turn it on/off,

also air-con pumps can have a plate on the pump just behind the pully wheel that you can see move and engage with a click when you turn it on/off, not sure if the bongo's one opperates in this way but worth checking because they can seize up and be resolved with a good whack ( turn engine off though first though )

check these things first and if nothing obvious appears then consider getting a service & re-gas

Does this help..

An estimated 10% of Air-Con gas permeates from the system every year.
Air-Con systems need recharging with gas & lubricant every 2 years.
Air-Con recharge service available from over 650 centres in the UK.
No appointment normally necessary- service operated on a drive-in basis.
Cooler air-conditioning or your money back guarantee

go direct to source, get passenger seat out of the way and look directly at the pump, when you push the button you'll see the clutch engage and then you'll know if your system is working or not, then get stuck into the possible causes.

Ok cant see anything moving behind pulley on pump. Difficult to see anything other than pulley that can move. Feeling body of pump cant feel anythig happening when tuning air con on and off

is it manual air-con or climate ?

because

if its climate there could be a problem with the pcb/electrical etc in the unit ?

or

if it's manual does the little green or orange light come on in the switch ?, cant remember what colour it is

if it doesn't it may help narrow it down to an electrical fault, rather than a nasty mechanical one

this link might help you with what to look for with the compressor when you switch the a/c on and off ( not a bongo but same basics ).

i know you are saying the problem is the radiator fan but i should imagine if the compressor doesn't kick in the fans would not run either

sadly looks like no easy fix then, seems the only other option is air-con specialist for a diagnosis/service/re-gas

atleast you had a go, you never know =D>
