Post Ventilation system makes ticking noise

When I turn my ventilation system on I hear a ticking noise coming from near the passenger side. It is not directly coming from any of the vents as I can find. Also, this happens with the AC on or off and on any setting. The car is an 04wrx sedan. I tried to take it to a dealer to have them look at it and It seems to be fairly intermittent as to how loud the ticking gets. The dealer didn't seem to thing anything was wrong. This is a very anoying problem so if anyone has any input it would be greatly apreciated.

Now... I don't want to alarm you, but there is a bomb in your ventilation system. Hopefully you still have warranty.

Is it coming from somewhere in the vents (or behind dash?), or engine?

Either something stuck in the fan, or there's a little electronic gizmo (i'm not exactly sure what it is, except that it regulates fan speed) behind the glovebox on most subies that tends to burn out leaving you with a smaller option of fan speeds...maybe it is ticking? It did this to me before it burned out.

I just took it out, resoldered it and stuck it back in...works like a charm.

leaves (or pieces of them) sucked into the intake is my guess... drop the blower out and clean it out.

Turn fan on high, turn off and repeat. Did the problem go away?
Happens to mine from time to time...that usually resolves it. I'm guessing small leaf against vent circulating fan blade.

The problem is intermittent, it will come and go. Turning the fan on high does not always help. Is there a post somewhere of how to remove the blower and clean that out. Sounds like stuff stuck in there could be my problem.

I had a similar problem. My issue was the condensation line was kinked. The condensation would fill the air box and drip on the fan. Occationally it would leak to the floor. I just unkinked the line and all was fixed.
