Does it cause the car to overheat?

 

Yes if I idle for too long, the cooling fan isn't being turned on when the coolant gets to the temperature in which it should switch on the cooling fan.

 

These cars don't use a cooling temp switch. The fan is controlled by the ECU which grounds to separate pins for either A/C control or engine coolant temperature control.

You need to inspect the wiring, especially the grounds. If you need the wiring diagram, send me a PM.

Sometimes my car overheats and when I look under the hood I notice that the fan is off and the water is boiling. When I hit my radiator fan it turns back on. I'm thinking it's the fan, but the thing is the fan on autozone, and amazon has this connection that looks different from the one in my car. It is a 2007 corolla ce 1.8. I'm yet to return the fan, just wondering if you maybe ran into something similar here.

Did you ever solve your problem?

 

The fact that it turns on when you hit it means there's a connection or grounding issue. You could replace the entire fan and still have the same problem. Gotta check ground and wiring. It could also be the motor is shorting out, and it "connects" when you bump it. In that case, replacing it would work, but you need to find out if it's the wiring (and the connector) or not.

If the one from AutoZone or the one online has a different connector, then you might be looking at the wrong one. I replaced my fan assembly with a TYC assembly and the connector matched what I had in my 2004 Corolla.
