Btw I may be in the wrong forum because mine is an engine swap, but I'm not for sure where to put it. So my Condenser fan wont come on leading to my engine getting hot in idle. I have tried everything i can think of. At first bought a new fan, didn't work. Then bought a fan switch, that didn't work. so I went online to look for some help some people used paperclips to jump the fan to make sure it is the switch, so i did that fan worked fine. so tried taking out the switch then putting it back it, that didn't work. then i thought maybe it doesn't have enough radiator fluid to tell the switch to turn on so the fan doesn't turn on. filled it didn't work. Please help what do i do now, did i miss anything?

-Thanks guys

Update: I tested the switch earlier just to make sure i didn't buy a faulty switch it works.

 

You are talking about the radiator fan then,

Test drive with the switch jumped and the fan running all the time and confirm there is no overheating. There are situations where the engine can overheat yet the fan will not come on, even though the fan system is working properly. The fan switch senses the temperature in the lower radiator hose not the engine. If there is no flow through the radiator (e.g. lack of coolant, or thermostat stuck closed), the fan will not come on.
