Having problems with your 2005 Chevrolet Cavalier ?
2005 Chevy Cavalier, ticking sound when the a/c or heat is on, sounds like it's coming from the passenger side.
That is something in the Blower housing on the interior. I had this same problem on my 2000 Neon. Turned out to be a piece of vent hose that wasn't trimmed correctly.
