I've tried searching for other posts, but can't find anything that relates to the issue I'm having.

I have a 99 Civic DX and for the last few months only get hot air coming out of the vents regardless of whether I have the dial set to cold or not. When the dial is moved to cold I also hear a clicking noise coming from behind the right side of the dash; it's hard to tell exactly where the noise is coming from.

The issue started after the CD deck was replaced. I checked the connections going to the climate control console and they were a little loose. I reconnected them, but that didn't fix it.

I've been searching around for possible causes and can't really find anything conclusive..hoping you guys can help me. Thanks!
