If fan,s are moving ,but not fast,the problem may be the fan motor,s them self,most fan,s do not move real fast anyway,but if you think they are running slow,it will be the fan motor,s,you might check the voltage to the fan,s and make sure there is 12 volt,s to them,but if you are straight wired i can only assume there is 12 volt,s there,,,check the fan motor,s

Most vehicles have 2 speeds for the cooling fans, high and low. When the coolant reaches a certain temperature the fans come on at low speed. If the temperature continues to rise they switch to high speed. This is usually controlled by the computer and a high speed fan relay. My Grand Prix has 3 fan relays. One for each of the 2 fans then a third relay for high speed. Perhaps yours is the same. Are you having an overheating problem? HTH. -Jim

I'm assuming that the engine overheats at idle. Like when stuck in traffic or waiting at the drive thru. I'd check the relays first. Since the fans will run when straight wired the motors are good. If the relays are good check the coolant temperature sensor. That's the sensor that tells the computer how hot the engine is. If that sensor is not working correctly the computer may not know to start the fans. HTH. -Jim
