It gives the description "Low speed fan relay control circuit" and "fan 2 control circuit" respectively. Where is the relay control circuit? And why would it throw a code for fan 2 when there is only one fan? Any more help on this old thread would be appreciated!
The codes are for high and low speed on the radiator fan. I would suggest manually checking the radiator fan by applying 12 volts to both the high speed and low speed on the radiator fan. When you go to do this test unplug the radiator fan plug. Also make sure the pins are making good contact on the radiator fan plug.

If the radiator fan and wiring is working properly check the ground wires going to the drivers side inside fender. Sometimes the group of ground wires get corroded and stop making good contact.

I'm not trying to sound like an idiot but I can admit when I'm clueless lol. How does one apply the 12 volts and check all that? I can do a decent amount of stuff on a car but the electrical has always baffled me.

I've noticed my car runs better in general when the engine light goes out and the fan will even kick on sometimes. Could that be a sign of a short or that it's not making good contact? The engine light comes on a lot but then randomly goes out. Sorry for all the stupid questions but thanks for hanging in there with me guys

There is a good chance the brushes are barely touching on the radiator fan if the P0480 & P0481 keeps coming up. I would consider getting a new radiator fan if the one in the PT Cruiser has been there for a long time. See if you have a friend that can help you apply 12 volts to the radiator fan with the radiator plug disconnected.

This is the second replacement fan. The first one I put in lasted 3 months. This fan stopped the day I put it in. As far as testing with the voltage, is it just a tool or something else entirely? I can go to a parts store if it's just a gadget 😊

When you replaced the fans, are getting the fan complete with the wire harness and new relays, or just the bare fan and reusing the short section of wire harness and old relays?

When my fan went out, the shop got just the bare fan. That fan was thought to have failed a short time after being installed, but it was actually a bad connector on the short section of harness to the main harness. They had to get another fan assembly to get the wire harness. Installed that and all has been good.

It had a connector attached to the assembly. I just plugged in the harness coming from God knows where in my car lol. I'm going to buy a multimeter and see if I can test the connections leading to the fan. I looked up a list that said to check the temp sensor and a few other things. I just really can't afford to take it to the shop so I've gotta take it one step at a time. Thanks for the patience and advice guys! Keep it coming please!

My new fan failed like rcstein's only it was the fan wiring harness connector with the female terminals, had become hot and loosened the terminals, namely the center terminal which was the ground.

It checked good with a Volt meter but the terminal was loose and made contact sometimes when connected. Look closely at the male and female terminals inside the connector for anything that looks burned or melted, it doesn't take much.
