Is the radiator supposed to turn on when AC is on?
Both radiator fans should always run when the AC compressor is engaged. Both radiator fans should always run when the coolant temperature sensor in the bottom tank of the radiator reaches about 212*F. Click to see full answer. Then, is the fan supposed to be on when AC is on? The fan only turns on when cooling or heating (in winter) is required.
Do you need to replace the condenser fan in a car?
Many cars use the same fan for both the radiator and the condenser though. Anytime the air conditioning is on, your condenser fan should be running. If you start the engine, you should see this fan spinning with the AC system. If it’s not, you need to replace it.
When does the cooling fan of a car turn on?
Many cars use an A/C pressure switch which, as well as a maximum/minimum cutoff, will turn on the cooling fan if the system pressure rises above a set point. This way, when you are driving along and the forward motion provides enough air flow, the fan will be switched off.
What happens if the radiator fan does not come on?
If the fan does not come on, something in the control circuit is defective. Simply so, does radiator fan affect AC? Yes, a broken radiator fan can cause the air conditiong to stop working. The AC system depends upon being able to dissipate heat into the engine coolant.

When does the condensor fan and radiator fan stop running?
Bingo, after a while BOTH radiator fan and condensor fan stopped running (high speed or low), and then for 30 sec of so, they will try to spin up for a split sec and stopped again and so on… It is at this moment the air becomes warm. This problem is not easily duplicateable.
