#6 of 8 2007 Grand Prix Cooling fan
Jun 04, 2010 (4:31 pm)
I have a 2007 Grand Prix with 3800 series III. Drivers side cooloing fan not coming on. Checked conector with voltage meter, no power. Checked relays by switching them and the seem to be fine. 30 amp J-fuse is also ok. Are there other sensors that could be problem. Also if ac is turned on will or should both fans come on?

The 2007 Grand Prix update: Direct wired fan. It is ok. Disconected coolant temp sensor still no fan movement. All relays and fuses are good. Followed wire to fuse block and found no power in fuse terminal. Completely stumped. ??? Every thing else on the panel seems to be working.

Yes when your A/C is on both fans should run but only part time. Passenger side fan should run constant while A/C is on drivers side fan off and on when thermostat opens.
