Dash noises 1 = chirp, other = ?

So I've got a relatively recent development on the '05 LGT. I've got two new noises from the dash that I can't nail down. These are not rattles. Whatever they are they're mechanical or similar in nature. I searched the forum but maybe my terms were no good because I couldn't really find anything that matched.

Noise 1 - This is an intermittent sound that I haven't been able to tie to the AC either. It's an intermittent chirp, that again, hate to coin some a silly animal reference but it literally sounds like a baby bird chirping lol. AC, recirc, no AC, I haven't been able to pin it down to any particular function within the dash itself.

Noise 2 - Happens when you shut the car off. You a noise that sounds like a rodent is trying to scratch it's way out of the dash. It's very odd, and that's about the only way I know to describe it. Sounds like it's coming from right behind the radio/ac unit. It goes on for about 30 seconds or so, then it's done but it does it every time. AC, no AC, doesn't matter.

Noise 1 sound like it could be the Blower motor. sometimes things get lodged in there or create noises on its own from constant usage.

Noise 2- no idea lol

I have those same noises. My guess is the blower motor going or might need to be cleaned. When I am done with my projects it's first on my list to check out.

#1 sounds exactly like the blower and I just ordered one from Ebay. I'll replace it as soon as it gets here.

I have one that sounds like it coming from my vent gauge cluster. but it ony happens when I'm moving. And the faster the car travels the louder it gets. Definitely coming front the front left of the dash. Any suggestions?

Sound #2?

I just replaced the fan motor and the sound of the chirping went away completely. The fan is for an 04-05 toyota Rav 4. It went in no problem.

Sorry for the late response guys. Went down to the coast for a couple of days and I'm just now getting back online. I'm sure you guys are right about #1. I believe that it is in fact the blower. I think that it chirps when it's running then when you shut it off, after it spins down it starts to go quiet, then all I can assume is that it start to freewheel from incoming air from the road and starts to chirp again? Just a guess.

The latter noise, who the heck knows. Something that is probably under vacuum until you shut the car off. Not sure. Meanwhile I'll do some checking on how much of a PITA it is to replace the blower. Unfortunately I now have a howling noise under the hood when the car is cold. Sounds like a pulley or idler that needs to be lubed. After it's warm, no prob. Oh well, atleast it's paid for. lol

Shotokan, thanks for the link. I couldn't find anything on a search but that's definitely it and is basically what I suspected, only I didn't know the technicalities of it.

I think this was covered in another thread, but Im not sure. If you remove the drivers side panel cover, there is a plastic clip holding the dash that people have had to do some "mods" to tighten the dash and stop the noise.
It happens on mine sometimes, was worse before I took some stuff off to install boost gauge, now I dont hear it as much

Yeah, I was thinking that was a "rattle" which I have as well, but this is mechanical.

The blower is not a pain at all to replace. It is just 3 screws.

Roger that. Thanks for the info.

I have stuck a small piece of black foam in between the windshield and the dash in both corners, it seems to have mostly stopped my rattles.
