My check engine light was on and when I hooked a tester to the car it said there was a problem with the cooling fan. The engine would overheat within about 10 minutes and I'd have to shut it off to let it cool down. I ordered a new cooling fan assembly (fan, motor & shroud). I installed the cooling fan and waited for the enging to heat up and the fan still doesn't work. I checked the fuse that I thought was connected to the cooling fan and it is good.

Is there a relay I need to check? Could it be the thermostat? Some other sort of electrical problem? Is there a way to check to make sure that the new fan that i bought works?

Did you check coolant temp sensor,i believe that sensor will control the fan to go on and off depending on the temputure of the coolant.

Haven't looked at the Sonata setup but many cars have a relay in the cooling fan circuit. I would check that first.
You should have straight wired the fan to the battery to see if it worked before you replaced it.
What exactly was the OBD code that you found?

No, I'm not sure how to check the coolant temp sensor.

I also could not find a relay for the cooling fan, but that doesn't necessarily mean there isn't one.

How would I straight wire the fan to the battery to check it?

I do not remember the OBD code, just that it said there was a problem with the cooling fan

Just run a jumper from the battery to the power wires of the fan. If there are only two wires. The relay should be in the power distribution center.

I have not had this issue on my Sonata but my Jeep had only two wires to the fan.

There is a large fan module at the left frame rail that gives fits... that is likely where the fan code came from.. look also at the harness for overheated lugs/melted connector..

BTW --- What was the exact P-xxxx code recovered ??

Whoa slow down with all this replacing parts stuff. LOL check the connecting harness. I had this same thing happen to me. I clean the engine bay alot and I found that the connector had rust on it to the point it wasnt allowing the fan to work. I ended up cutting the harness and splicing the wires. No more problems.
