How does the ECM work on a Chevy Malibu?

The ECM receives the input from the ECT sensor & passes that on to the BCM which in turn passes it on to the instrument cluster. The weakest part of that chain tends to be the engine-mounted sensor itself & its wiring. But a breakdown can happen anywhere in that chain.

Why does my AC not work when temp is low?

Under normal circumstances you would be right. The ECM provides both power and ground to the ECT which is a variable resistor so when system voltage starts dropping (which is a result of corroded battery terminals) the temp readings are incorrect and since system voltage is low the ECM cannot read them correctly either.

Why does my Chevy Equinox heater keep blowing cold air?

At the time of writing this it is the 9th highest problem trend and climbing. Automatic heating systems in cars use a temperature blend door that controls how air flows past the heater core. The blend door is connected to an actuator by a plastic arm that is prone to breaking in the 2006 Equinox.

What should I do if my Malibu radiator fan is not working?

The first thing that you would want to do is locate the fuse for your Malibu’s radiator fan and make sure that it hasn’t blown.

Where does the antifreeze smell come from in a car?

Why does my car heater smell bad when I turn it on?

If the smell is coming from inside the car only when the heater is turned on, the problem is either with the heater core or the heater hose. If you only notice the smell outside the car, the leak is in the coolant compartment. Reach near the floor on the driver’s side and pull the hood release.

What to do if your car has antifreeze in it?

Examine the heater core for a leak. Leaks from the heater core usually result in the antifreeze running down the side of the heater or dripping onto the ground underneath the car. Locate the coolant compartment and examine it for leaks.
