There are a few possible causes for this issue with the air conditioner turning on by itself in your 2008 Chrysler 300 Touring:
Automatic Climate Control System Malfunction: Your vehicle may have automatic climate control system that is designed to turn on the air conditioner when the interior temperature gets too warm. If there is an issue with this system, such as a malfunctioning temperature sensor or control module, it could cause the air conditioner to turn on by itself.
Electrical Short: An electrical short in the wiring or control circuitry of the air conditioner system could cause it to turn on by itself. This could be caused by damaged wiring, a faulty relay, or other electrical component.
Malfunctioning A/C Control Switch: The air conditioning control switch itself could be malfunctioning, causing it to send a signal to the A/C system to turn on when it is not supposed to.
Ghost Signal Interference: It's possible that a remote signal or other interference is being received by the A/C control module, causing it to turn on the A/C system.
To diagnose and repair the issue, it's recommended to take your vehicle to a qualified mechanic or dealership for a full inspection and diagnosis of the A/C system.
An E2 error indicates a problem related to the inlet cold water temperature sensor. The sensor may be sensing temperatures outside normal parameters or the sensor itself may be defective

Hi,
Please check the auto programmed ON/OFF on your remote commander. May be the auto programming is running that run your air conditioner all time without stop. Check also your temperature setting.
To hard reset your remote , remove the battery and wait for 1 hour and replace the battery. If your remote has reset button just go has it reset.

E4 means return air sensor error, if the error cannot reset may be the return air sensor is out of range or defective. But if the sensor is ok you need to replace the control board itself. The reading of return air sensor is 8k to 10k ohms @ 25deg. C temperature.
