I had a minor a minor fender bender at which messed up my radiator and A/C condenser. I have replaced both of those but my van is still overheating. Only one fan is working. Is that why its overheating still? If not what should I do next?

Hello,

In order for the engine to run the correct temperature both of the radiator fan needs to be functional. Otherwise the one fan just does not pull enough air to cool the engine.

Check to see if you are getting power to the electrical connector of the inoperative fan. If no power then you have a wiring issue, may be a short in that harness. If you have power, then likely a bad fan motor.

You can put 12v power source to the fan connector to see if it comes on.

I have attached diagrams for your reference.

Please let me know of any questions.
Thank you.
