92 regal custom 3.1 radiator fans won't turn on?
My radiator fans won't turn on. I've replaced the relays, thermostat, coolant temp sensor and coolant temp sender. Wired the fans directly to the battery and they both turned on. What's the problem? The mass air flow sensor was replaced as well as the ecm and crankshaft sensor. We disconnected the battery for 10ish minutes to reset everything. The fans just won't turn on. Could it be bad wiring??
