Is it the ECU or something else?

I notice that there is a little bit of delay on my fans once i turn my ac on. It takes a few seconds for them to start up. Sometimes the driver's side fan doesn't even spin, and i have to bang around the area and it will start up. Not sure if its my fan motors acting up, or something else that is causing the delay.

 

Its the ECU...

 

so i guess before i attempt to get my car fixed, i should try the reset ecu method to see if that will fix my problem?

 

Are you actually having problems ( car overheating or a/c not working ) or are you just worried that the fan operation doesn't seem normal? Both fans are independant and the ecu decides when to turn them on based on various factors.

 

I see... well I am having overheating issues when my car is idle. This seems to happen when the A/C is on. It use to start blowing warm air out after letting the engine idle for a few. But now the overheating problems seem to be going away and coming back. So I am just trying to pinpoint where the problem is. Seems like its my fan tho. Cause when I bang around the shroud area of the fan, the fan starts spinning up. My fans just act differently a lot.

 

My a/c has went from high to low before on it's own, but just briefly. It dips down like I set it to the lowest setting, then goes back up again and all is fine. I haven't searched the issue or anything, so I really don't know if it's a problem or normal behavior.
