Car is a 94 Grand Prix SE sedan, 3100/4T60-E with 139k.
Niether of my cooling fans are kicking on. The primary doesn't turn on at all, and the secondary doesn't turn on even with the a/c (although niether does the compressor). The coolant temperature sensor near the thermostat housing looks to be new, but I'm not sure if that's the one for the gauge or for the ECM (there were two separate ones if I remember right). Where's the second one?
BTW--The service engine light was on last week due to a vacuum leak, and the fans kicked on with the light then, so I think that rules out fan relays/fuses/most wiring connections.
