2005 overheating town and country with check engine light
Hello, I am new to this site and am looking for some assistance. I have a 2005 T & C with the 3.8L V6. last week the van while sitting in traffic started to overheat. I turned on the heater and was fine. After this event I got a check engine light that has stayed on. Then four days later it overheated for my wife in a similar situation while sitting in traffic.
I checked the coolant level and it was good. I checked the fuses and relays that control the fan and they seemd ok. I did another test last night in the garage. The large two fan cooling assembly never turned on. I am thinking it is some sort of relay or temparture sensor that is not telling the auxillary cooling fans to turn on and off. Could the thermostat be going bad?
Any ideas or suggestions on how to repair or trouble shoot? Any help would be appreciated. Thanks.
