I owned a Blazer 4×4 1999 and this did not happen while using the 4×4 feature. Also, sometimes the engine is too noisy due to the cooling fan. The engine losses power and the fuel consumption increases. Now this situation is more frequent and it seems that the cooling fan is engaged at all time.

Why is my 4 wheel drive not working?

It all started with a 4WD drive switch. Like many car repairs, it all snowballed from there.

Instead, it broke off–through no fault of my husband I’m told–and the 4×4 service light popped on.
