Need help !!! Condensing fan doesn't work at all.

Hi all, I have big problem about air conditioning.(my car is Toyota van diesel engine). At this moment, a condensing fan doesn't work at all but the fan motor is okay.(connect battery voltage to the fan socket,it works normally).I have no idea where I have to check.Today, I have removed a lugguage box and behide it there are a lot of connector . I don't know which one concerning the condensing fan control circuit.Any advice please .
More information ==> A/C button on dash doesn't work. When I try to push it on and off , there is nothing to compressor. Actually, when I push it to off , the compressor must cut off,right? Is it this concerns with condensing fan?
sorry for bad English.
thanks

Today I have removed glove box and take a photo.Could you tell me which one is condenser fan relay?

Does anyone know what the resistant located beside condenser fan is for?

Worren, most of us here on TVT are in North America. I'm not sure about Canada, but here in the US we never had diesel vans. Your van is different enough that I'm afraid to speculate on the problem & or offer any specs that may or may not apply. My advice would be to purchase a factory service manual for your specific model and use that to get the information you are after. Good luck. Tim
