You go to warm up your car on a chilly morning only to find that your car heater is not blowing air, at all. Our mechanic explains what could be causing that, and how to troubleshoot, diagnose, and fix blower motor and blower motor resistor issues that are probably to blame in this video:
Over the last century there have been thousands of really amazing automotive achievements, and then there have been truly awful failures. Today, I bequeath to you the latter.
I was at a car show over the weekend and saw this really great absolutely terrible “feature” on a late 1920’s – early 1930’s vehicle.  I am leaving it’s name out intentionally. The “feature” is a heater, which obviously sounds like a good idea right? Well it is, but only when executed properly. This design was excellent use of creativity for sure, but heavily lacking in foresight in my opinion. It was a cast iron box that mounted to the top of the exhaust manifold that basically funneled exhaust gases cool outside air through it, warming it up, and shooting it into the interior of the car to warm up your little toesies. This is all well and good until there is an exhaust leak or a cracked exhaust manifold. Then Mr. Carbon Monoxide walks into the place and spoils the winter time party. I don’t know about you guys, but this gives me a new appreciation for my heater core and blower motor.
