2004 honda accord radiator coolant fan not turning on
#21
You either got a bad new switch from O'Reillys or the switch doesn't close at the proper coolant temperature to turn on the fans. If you have your original sensor and it wasn't damaged, then reinstall. If not, I'd spend the extra money on a Honda switch.
The reason the a/c isn't turning on the fans is the a/c system is discharged, so the pressure switch is not close and is disabling the a/c system. Evacuating the a/c system with a new desiccant bag (since the system was open) should fix the problem.

Since your a/c system was open, I'd change every o-ring in the system and the receiver/dryer. Button up the system, make sure it holds vacuum, then recharge. The system should be in good shape from a leak standpoint for a long time.

Cooling fan not working
Let me jump in this old thread and see if I can get some of that knowledge you guys have for my cooling fan not working.
2004 Accord EX sedan 4 cyl
Both fans come on with the windshield defrost setting and a/c setting. The radiator cooling fan isn't coming on by itself though. Let it warm up for about 20 minutes. Checked all the fuses, jumped the relay and fan comes on fine. The car is not overheating, it's sitting at normal temperature after it warms up without turning the a/c or defrost on to kick on both fans. Normal heat and it sounds like the thermostat/heater core is opening when turned from cold to hot.
In other words, the car seems to be operating normally, great heat and great a/c, just the radiator cooling fan isn't cutting on alone. Is it just not getting hot enough? It's strange that both fans operate when the a/c or defrost is on and everything is running fine and no over temp. I'm scratching my head. Thanks in advance for any guidance!
