    Cooling fans not coming on HELP!

    My sons 99 Camaro, 3.8, threw a P0480 (Cooling Fan 1 Control Circuit) and P0481 (Cooling Fan 2 Control Circuit) codes today. The cooling fans are not coming on even when the AC is turned on. The temp is only going to 210 right now. Any ideas what might be happening?

    Thanks

    First thing to do is check the fuses and relays. Then jump the fan connections to make sure the fans actually work. Even though it seems hard to believe that they would both die at the same time.

      Oh yeah, I forgot, check the wiring for the fans, too. Since neither one works, maybe there's a bad ground somewhere.

        wana fast test? turn the key on. Then fine these 2 wires. http://shbox.com/1/fan_switch_wires.jpg one at a time remove some of the wire sheeth and ground the wires. you should get low speed with one grounded and high speed with the other.

        Tell me if they come on or not and then we can go from there
