There is a black fill plug on the very top of the transmission. It is below a wiring harness and an AC line (I Believe).
In a 2003 Saturn Ion, the low-pressure cutoff switch for the AC system is typically located on the accumulator or the receiver-drier, which is found near the front of the engine bay. The switch is generally mounted on the side of the accumulator, making it accessible for testing or replacement. To confirm its location, you may refer to the vehicle's service manual or consult an automotive technician.
Under the hood
Dexcool don't use any other type
On a 2004 Saturn Ion, the AC drain is typically located on the passenger side of the vehicle, underneath the dashboard. It usually extends through the firewall and can be found near the bottom of the evaporator case. Look for a small rubber or plastic tube that allows condensation to escape from the AC system. Regularly checking and clearing this drain can help prevent moisture buildup inside the vehicle.
You most likely have a bad a/c - heater controller........
If you want it constantly running jumper the high pressure cut off switch wire. And if you dont want it running turn off the ac. If pully is seized see if a napa can get a shorter belt to route around the ac compressor
If they share a common engine then it may. The 8th digit in VIN is the engine code. You can also tell by visually ensuring parts are identical.
The AC evaporator in a 2003 Saturn Vue is located inside the vehicle, typically within the HVAC housing behind the dashboard. To access it, you generally need to remove the dashboard and associated components to reach the evaporator core. It's recommended to consult a repair manual for detailed instructions or seek professional assistance for this task.
To remove the AC expansion valve in a 2003 Saturn L200, first, disconnect the negative battery terminal and relieve the AC system pressure. Next, remove the dash panel to access the HVAC unit, then disconnect the refrigerant lines from the expansion valve. Finally, unbolt the valve from its mounting position and carefully pull it out. Ensure to replace any O-rings and properly evacuate and recharge the AC system after installation.
Most of the time it means that the AC refrigerant has leaked out or that the AC doesn't work for some reason. Understand that most vehicles engage the AC when the defroster is on because the AC will dry the air, clearing the windshield quicker. If you turn on the Defroster and the AC light flashes, it just means that the AC won't turn on.
To replace the AC evaporator on a 2003 Saturn L200, you'll need to start by disconnecting the battery and draining the refrigerant from the AC system. Next, remove the dashboard and the HVAC assembly to access the evaporator. After unbolting and disconnecting any attached lines, you can replace the old evaporator with a new one, reassemble the HVAC unit, and reconnect everything before recharging the AC system. Make sure to check for leaks and proper operation once the installation is complete.
