Does anyone know what kicks the fans into high on the 2013 Avalanche ? It seems my temp stays around 195 to 200 and the high speed setting of the fans kick in whenever it wants.
it could kick in at 195 or 200 it doesn’t seem consistent with a set temp.
the low speed will run constant at these temps until it kicks into high.
When they kick into high my battery voltage drops down to 12.5v and goes back up to 14.5v after awhile once they go off.
I think I have a bad alternator but would like to find the set point for the fans.
