2002 Chevy Cavalier Check engine light/cooling fan

2002 Chevy Cavalier 40000 miles

Hi, I’ve had this problem for a few weeks now and I hope someone can help me fix it. I own a 2002 Chevy Cavalier with approximately 40 thousand miles. About two weeks ago when I was warming up the car on a very cold day I noticed a burning smell coming from the heater vent. It smelled like plastic burning. After a while the smell would dissipate as I drive and no other problems were noticed. I checked the anti-freeze and oil level and everything is ok. About a week ago the check engine light came on so I took my car to Advanced Auto Parts and had the salesperson put on the diagnostic tool to check what the error code was. It came up with p0480, cooling fan #1 relay. I bought the new part, put it in, had the salesperson reset the fault code and away I went hoping the problem was fixed. Everything was ok until later that night when I went to go to work and the check engine light came back on. The engine is running “slightly" hot as it was before the fix at 195 degrees and I noticed that the radiator fan is not turning. I am not sure if it is supposed to turn all the time, but I assume it should. I no longer notice a burning smell coming from the heater vents either. If anybody could help me with this I’d greatly appreciate it. Thank you for your time. Chet
