Fan isn’t working when ac is turned on. I can use a scan tool and command it on with the scan tool and it comes on when engine reaches the temperature needed to command them on but it doesn’t work with the AC on. Any advice on what to check is appreciated thank you

 

im having the same issue. tho with the scan tech 2 tool, i can see in the hvac disabled history log it shows unstable rpm speed... around 680-700rpm on idle.. tho the engine idles just fine n quite. ive messed with even vacuuming back into the R134A cans. nothing changed other then pressure low message showing up when i take too much out.

its like the fan acting on wrong information. so it won't kick on at idle and stay on..

you having the same symptoms?
