Howdy,
I have a 95 Explorer XLT 2x4. I don't believe the AC has ever been serviced. It has progressively blown less cool over the years, until about a month ago it now just blows hot air.
If I turn it on now for a few seconds, I get a funny smell coming through my vents, like ozone or something.
Is this normal for the AC to progressively get warmer, and is the solution normally just to have it recharged?
Or could this be a sign of a bigger problem?
