Front fans do not come on - 2003 Oldsmobile Silhouette

engine rad fan, AC front condensor fan.???
all have fuse
all have relays
we test those
and even hot wire fans to make sure fan even works.
or cab blower fan dead.
we can not guess fans, ever, learn to be specific, even tell
exactly where it is.

Should have a ballast resistor which controls fan speeds.

Can you hear the front ac/heater fan? They use the same AC compressor so that should be okay. The fan switches fail quite often on those. That controls how much air is pushed by the fan for AC, heat and defrost. The switch is attached to the fan knob on the dash.

Then you need to diagnose the front fan circuits. You can start by checking for power and ground at the connetor to the fan motor.

The front fan is a slow spinning ac fan, the rear rad fans are for cooling and also ac at times, if the car is overheating then you may need to check the coolant fan sensor,or the thermostant,

disconnect the cooling fans and jumper the cooling fans if the fans run and the fuses/fusible links are good the it may be the fan control module which is in front behind the grill

Replace the resistor in the front fan system.

no the fan in front of the radiator is actully in front of the a/c condensor and serves to pull are across it for the a/c system. no fan on the motor will over heat the engine

replace your fun
