cooling fans not running on a 2001 pontiac montana

Asked by Jan 26, 2017 at 09:42 PM about the 2001 Pontiac Montana Base Extended

Question type: Maintenance & Repair

The car was giving a 0128 code. Replaced the thermostat because it was stuck open. Also replaced the temperature sending unit in the thermostat housing. The gauge reads the temperature but when it goes over 220 the fans will not come and run. If I disconnect the sensor wire the fans will run but the gauge does not show temperature. Replaced the fan relay. When I turn the A/C on high the fans do not run either they used to. Is the coolant level sensor causing the problem. Need help

Sounds like the coolant temperature sensor. Replace it with an AC Delco sensor. For some reason many aftermarket sensors don't work well or at all in these GMs. HTH. -Jim

Where is the connector plug located
