Cooling System For 2003 Chevrolet Malibu Gmpartsdirect The fans come on if i unplug the coolant temp sensor (although the car runs like crap with it unplugged) if i jump the fan 1 (location #12 on the fuse box) relay with a fused jumper wire from pin 30 to 87 both fans come on (seems like low speed). if i jump fan 2 (location 14) from pin 30 to 87 passenger fan comes on (seems like high speed). Hello, fairly simple system, there are three relays and two fuses for the cooling fans. and the power control modules turns the fans on and off. if both the fans dont work, check the fan mode relay. this relay controls both the fans. here is a wiring diagram to help. also the pcm simply provides a ground for the relays, to turn on fans. there also is a ground fuse for the cooling fans check. 1 post · joined 2017. #1 · mar 4, 2017. the cooling fans in my 2003 malibu. i replaced the temperature sending unit, i jumped a wire at fuse block relay and the fans work. i replaced the relay. i had the battery disconnected, when i hooked it back up the check engine light came on. the code was for the relay, temperature sending unit, wire in.
