On a 97 cadilac were do i start to trouble shoot the engine fans
Country: United StatesMake: CadillacModel: SevilleYear: 1997Engine: V8
I start with using a homemade harness that connects to each fan motor on one end and the battery positive and negative terminals on the other end.Hook the jumper to each motor to test operation and see if the jumper gets to hot.Next i test for power and ground to the fan relays.If that all tests good I will replace the relays next.This will usually cure the problem.
Were are the relays located on this car?
The 3 cooling fan relays are on a bracket on the lower rear radiator support facing the engine in the middle between the cooling fans.They are accessed easiest from under the radiator area.
