Dodjour Posted December 2, 2018 Report Share Posted December 2, 2018 Can anyone tell me the parameters for wich the electric cooling fans turns on/off? it’s not causing overheating issues in the engine but it is causing A/C issues. At idle it will kick on but only for a few seconds then kick off and continue to do this regularly every few minutes. I want to know what is telling it to kick on and what values it used so i can determine the problem, or if there even is one. Quote Link to comment Share on other sites More sharing options...
jkeaton Posted December 2, 2018 Report Share Posted December 2, 2018 (edited) Maybe you’re low on refrigerant and the compressor is also cycling which makes the fan cycle. Just a thought. Edited December 2, 2018 by jkeaton 2late4u 1 Quote Link to comment Share on other sites More sharing options...

jkeaton Posted December 3, 2018 Report Share Posted December 3, 2018 Does it do it when not using AC? Quote Link to comment Share on other sites More sharing options...
Dodjour Posted December 5, 2018 Author Report Share Posted December 5, 2018 I have manifold gauges and have checked the pressure verified by a certified tech. Yes fan acts the same with AC on or off Quote Link to comment Share on other sites More sharing options...
