Squealing/Chirping behind driver dash

Hey all,

I'm getting a squeal and chirp noise on. 2004 limited v8

Here is a link to what I could record: https://www.youtube.com/watch?v=eHiIOAdW-1M

Any ideas on what this might be?

Thanks!

 

The video is marked 'Private' but a squealing noise coming from the dash could be the HVAC blend doors or your HVAC blower motor. Is the noise rhythmic or random? Rhythmic is probably the blower motor, random is probably the blend door actuators.

 

Made a new video here https://youtu.be/tG8BDsXHWdY?si=BFqOGflny-iAfT-o maybe the break abs pump?

 

Oh ya that doesn't sound like what i was thinking it could be.

You may be onto something with the ABS pump. Or, is that the electronic brake booster? Or are they the same?

 

It looks like its this part "Brake Master Cylinder Assembly With Fluid" 47050-60081 which is about 1k at the cheapest I could find, rough.

 

I wonder if it could be rebuilt?
