2003 Chrysler PT Cruiser: turbo..overheating..the cooling fan..Circuit

Customer Question

I am working on a 2003 Chrysler PT Cruiser 2.4 turbo. The car is overheating looks like because the cooling fan isn't working. I have a code of P0480 "Fan code Circuit". Can you help me diagnos the problem. Also I don't no if this is related but when I turn on the A/C the idle goes extremely low almost stalls. Help

Good evening, chances are that one of the speeds on the fan is bad. It is recommended to use a scanner that can actuate both the low and high speed fans to see if either works. Another method is to gain access to the fan connector from under neath. There is a 3 wire connector for the fan. The outside wires of the 3 wire connector are the 2 power wires for the fan. One is for the low speed and the other for the high speed. The center wire is the ground. You need to actuate the fan with the scanner and then check for voltage at either of the outside wires to see if 12 volts is present. You can try to use a jumper wire hooked to battery voltage to see if you can make either of the speeds work. Just be careful because if the fan draws to much current, it can cause the jumper to overheat or even damage the circuits. I personally use a "Power Probe" that has a built in circuit breaker than protects the system in case of excessive current draw.

Ok, we tried turning the fans on with the scanner it does give us the menu to do so but when we try it say's. "Test not supported" so we can't get the fans to turn on. Also we are only finding a four wire connector to the fan not a three wire we have put pwr to each one wire and the fan isn't turning on. The wires are brown, black,pink and yellow. What next?

Sorry its hard to accept when I no one ever got back to me I waited all day. So I really got no help.

Can I get you to check the violet/red wire at the fan assembly to see if there is battery power there. If there is check the dark green/orange wire with engine running. There should be power with engine running. Let me know, thanks!
