only on the first morning start the cooling fan kicks on for about 30 sec just after its started then it turns off, this is the 4th day its been happening, a while back i was overheating and the high speed fans would come on but a thermostat fixed that issue, could this be related or is there another issue that wont throw a code? very strange i say

 

anyone?

 

Is your Defroster or AC on, they both use the Compressor and if it comes on the cooling fan does also.

 

no, but now that you mention that if my heater settings are off and the heat dial is at full cold the fan comes on, if my heater is off but set to heat the fan doesnot come on, weird

 

I wonder if it's possible the sensors for the fan were damaged by the "overheating condition"? That kind of thing used to be a problem back in the day.

so we have somewhat figured most of it out, on a cold start the ac condensor turns on and then the fan, about 10 sec after its started you can hear the ac clutch kick off and about 30 sec after that the fans click off, does anyone know what is causing the ac to turn on cold start?

 

the ac condensor clicks on at cold start then the fan runs, about 10 sec after start the clutch kicks off and 30 sec later the fan does too, all heat settings to cold and off, if i turn the heat dial from cold too hot the clutch and fans dont turn on??? anyone know what might cause this with no codes?

 

please help?? anyone have an idea?

 

My '12 has always started with everything running wide open, even well below zero. The fans shut down in a few seconds. Most likely because in the cold i always start the defrosters on high, full heat to warm up the glass gradually (had a windshield pop from thermal shock years ago and it was not fun). The defrost air will warm up very slowly as the engine warms up while I am brushing off the snow. My defrosters are always on at cold start, it is just a habit I have, turn the defrost on high when I shut down so it is ready in the AM, winter or summer.

My 2014 3.7 has the fans coming on at cold startup. Has since new regardless of temperature.

 

ac was low and refilled, no more cold start fans.....
