Please help.

have just got a Smax 2008 2.0 tdci. Found air con not working.

Have found a break in the PWM wire feeding the fan and reset fault codes but air con is still not working.

Have 14 v at fan, PWM unit cable 12 v when connected to the fan and 4.4v when disconnected.

Really just want to prove the fan will come on when the engine is hot, have left the engine run for 30min but not much past the mid way point on temp gauge.

as towing a caravan just want to make sure the fan will kick in when temp of engine gets too hot. Is there a way of testing/ disconnecting a sensor to get fan to start.

Air con not that bothered about as have windows.....

Please help

Thanks

It could be an issue with the refrigerants, are you sure the system is full?
