Sprinter Tempmatic

I have a Benz Sprinter (Transporter cargo van) 8AC9036615A929267 313 CDI with a Tempmatic AC set-up. [/align]This model doesn't have the roof or rear option cooling, just front passenger area.[/align]The auxiliary fan to cool the condenser doesn't come on. a/c work fine for the first 15 min and then nothing. [/align]I have been able to trace as far back as the absence of apositive value that's neededto energize the relay and turn on the fan. I have been told that there is no control box as everything is built into the switch assy.[/align]What is required in terms of inputs to allow the switch assy to energize the relay and turn on the fan ??[/align]I am thinking evaporator temp and ambient temp value but what else ?? Does the fan stay on as long as the compressor does ?? do they cycle together ?? [/align]Can you please assist ??[/align][/align]Thanks in advance.[/align]
