Re: [DML] What would cause my blower fan (A/C) to quit after 1 minute?



Excess heat is often caused by the spade terminals, I always replace with an eyelet type and re-crimp the connectors

40 is for the fans up front. 25 is plenty for the blower. If a good, relatively new 25 amp breaker is tripping on the blower, the blower is bad. When blower motors fail they pull too much current. But even at this they would only trip the breaker on speed 4 as speed 3 has a resistor in the path that reduces the current. 

The reason it works on speed 1 and 2 with a bad breaker is that the breaker is not in the circuit at all at those speed settings. 

The other 25 in the kit is for the lock module. 

As breakers age and corrode, they tend to trip out at lower currents since the contacts inside get hot. A properly functioning breaker in the fan circuits should not be hot to the touch.
