A couple of days ago, my engine overheated in stand still traffic. I’ve been having issues with the air conditioning not functioning when I’m not moving, but when I’m going forward it’s not a problem. My father in law checked it out and found that neither fan on my radiator unit would turn on.

Things we have done:
- Confirmed all fuses and electrical connections are good
- Replaced the relay/fan unit

Things we know:
-Temperature gauge appears to be functioning correctly (showing rising temperatures, etc.)

We don’t know where to go from here.

Good afternoon,

Did you check for power to the fan motors?

Let us start with checking the 60 amp fuse for power on both sides.

Fuses, wires, and sensors are all getting juice.

Do you mean there is power to the cc fans?

As far as we can tell. We checked all wires and connections with a voltmeter, and were able to hot-wire the fan. It just doesn’t come on when the car is running, and I can only get cold A/C when the car is in motion.
