This is driving me in circles, ABS Inop light comes on, Traction Control turns off, and fans do not operate. In the beginning this would happen for about 5 min, then everything would come back and be normal for days/weeks. Now everything is off and not coming back on. Seems to be all linked. Checked every ground could think of, and all the relays/fuses. Pull the temp sensor, fans turn on. Anyone else ever have this problem or know a solution?

 

Those items and the horns are all fed from fusible link K. That is one of the gray "2.0 SQ MM" ones in the bundle atop the shock tower near the battery. Try turning on the ac to force the fans on, and wiggle all of them one-at-a-time till you find one that is intermittent for the fans.
