Reading through past threads on the subject left me with questions. I have verified the strip fuse is good. Resistor is new. The fans do not operate on low speed or high speed with engine at operating temp with A/C on or off. Both fans operate when powered at the connector behind the drivers side light. The fans do operate when the two white blade connectors in the same location are jumpered. Do I understand correctly that unplugging the coolant temp sensor should enable the fans with the key on? If so, does this indicate a faulty sensor? How would I verify if the problem is the "dual cube relay" behind the fuse box? On a side note, does anyone have a picture/description of what all the cube relays control in this location or where I might find one? Again, this refers to a 92 model.
