It can reduce carbon emissions by pumping fresh air from outside into the exhaust stream. By the time fumes leave the tailpipe, there are fewer hydrocarbon pollutants in them.

Which is a symptom of a fuel pump problem?

Can a Ford Fusion run in hot weather?

My car (2011 Ford fusion) does the same. When it’s cool outside, the ac runs forever. But in hot weather, it might blow cold air from 5 seconds to 5 minutes. In super hot weather it’s not even worth trying.
