I have tried to get video of what happens, but have not been able to catch the noise while trying to record.
In the meantime, I wanted to start getting your ideas on what might be happening.
2004 Tahoe Z71 with 200k miles
Sometimes, I get a random very loud buzzing noise inside the cabin that sounds like it is coming from the front of the console, where it meets the dash. It can come in a burst pattern of two or three buzzes.
While not an exact match, the noise reminds me a lot of this sound...
Catches me by surprise and makes me practically jump out of my seat whenever it happens!
Feels like its the end of a hockey game period.
It happens more frequently just after start-up, but can also happen at random times after having driven around town a bit.
I was thinking (and hoping) it is the lower HVAC temperature door actuator, which is easier to get to.
Strange thing is, the sound has happened even when the HVAC is off.
Any thoughts until I am able to capture video of this thing in action?
I have a Tech 2 and already played with recalibration of HVAC actuators. Plus, the battery had been disconnected a bunch of times for more than 30 minutes, while I had done other work over the past year.
This is not an emergency for me, but I am curious to see if I can try to figure it out without throwing a bunch of parts in.
I have a Z71 roof rack coming this month (my Z71 has no rack now), so I will be getting that before tinkering with this buzzing noise.
Thanks in advance!
