New guy on here
 

I am really new here

I just want to start off by saying that I have an annoying problem with my truck. It is a 1999 Chevy Silverado 5.3L V8. It makes a chirping noise when the weather is wet or humid outside. The noise goes away once the truck heats up. Any suggestions?

Welcome Julio!

I would make sure that your throttle body is clean. They can be finicky when it's humid

Welcome to Truck Forums
Glad you joined, hope you can stick around for a while.

Can you be more specific of your chirping noise?
Does it happen intermittently.
While truck is moving or at stand still?.
Does it speed up or slow down with vehicle speed?
Can you tell where it is coming from? under truck? from a wheel? from engine compartment?

The noise may be from the suspension. A good under wash might cure it. Welcome to the forum.
