The likely cause of a 2015 Tahoe’s Radiator Fan not turning off is a faulty Fan Control Module.

2015 Tahoe Radiator Fan Won’T Turn Off

If your 2015 Chevrolet Tahoe’s radiator fan has stopped turning off, there are a few possible culprits that could be behind the issue. The fan is an important part of your vehicle’s cooling system, and a malfunctioning fan can lead to further damage if left unchecked. Finding and solving the issue can require some detective work but is generally a straightforward process. First, check your coolant level and top up if needed. If this doesn’t solve the problem, look into the engine temperature sensor or thermostat. A faulty thermostat will usually cause the fan to stay on too frequently or too long after engine shutdown, while incorrect temp sensor readings can cause the fan to stay on when it shouldn’t. For an accurate diagnosis, you may need to consult a technician or take your vehicle in for repairs.
