Why does the radiator fan only come on at 35 mph?
It rarely comes on at speeds over about 35 mph because at that speed enough air is forced through the radiator to keep the engine at about 198 degrees. I would start by looking for a blown 30 amp fuse under the hood.
Why is the fan not working on my Chrysler 300?
The fan wiring is some of the more vulnerable wiring in your 300. You can test the voltage going from the fan relay to the fan itself. If it is getting 12+ volts, the fan should be coming on. But if it’s not, which means the fan has gone bad.
Why does my Rad fan stop running high?
Vacuumed it down, and noticed a small release of the vacuum. We put 24ozs of Freon in and the high fan speed stopped running high speed. So I waited till the next day went to his shop which was 90 miles away. The ac worked great on the way there. Vacated the system down again and removed the expansion valve.

If you do have low coolant, don’t fill it up until the engine has cooled off. Adding coolant to a radiator dry enough not to trigger the engine temp sensor can cause problems from drastic temperature change. Let it cool down first.
Why are the fans not coming on in my truck?
With my scanner hooked to the truck, the engine temperature will go up to 220F and fans will not come on. After reading several forums on the issue, I understand that there are two wires that are “grounded” in the PCM to make the fans cut on. They are a GN wire in Connector 1, Pin 42 AND a Blue wire Connector 2, Pin 33 of the PCM.
