sizzling noise in dash

[Maddog7]

Hello everyone,

I have 2019 5.7 hemi and this morning I noticed a sizzling noise from the dash. It sounds like it's coming from where the tach is located. When I am at a stop the noise seems to go away. I monitored the tach and it seems that the RPM does not influence the noise. It picks up only as I gain speed. I did check to make sure I had nothing rattling in the side of the door, thinking and hoping it was just spare change rattling, but the noise persists. Seems like a shot in the dark, but thought I'd post it here and see if anyone here has any ideas. Thanks in advance.

did you by chance slide this selector from "mail" to "bacon" ?

Does your truck have active noise canceling ?

If so maybe it’s acting up.

You may not want to park in your garage until you are sure it’s not gonna catch on fire.

Do you have a scanner to check for DTCs?
If not, most parts stores will scan for free.

It might be better if you can scan while moving and the sound is happening, but you may see an electrical-related DTC regardless, if there is an electrical issue.

Do you notice any irregular smells in the dashboard area?

This might help to point you in a direction.

And, to Ram Forum.

A/C system refrigerant expansion? My wife can hear what she calls a hissing or sizzling noise in our 2020 - I can't hear it due to being an old far$. Noise goes away when A/C or Defrost is turned off.

Maybe someone left a George Foreman grill in there

Lol...I will check the bacon setting first. Lol. Actually I will try the DTC scanner as a first step and see what that tells me. Thank you.

I watched a video on a car with a noise that the dealer could not fix, Dave's auto service tec just completely closed the passenger window that was down a hair or 2.

But in the dash? Did you turn radio off, do a nose check,
If you had a short in power wire, should take out fuses, you hope.
I don't know anything about the auto noise cansilling in these trucks.

Blend door?

Could the sound also be described as sand hitting the windshield?

I once had a car that had a windshield seal that started buzzing at higher speeds.
