Passanger Side Draft

[hoorders]

Hello everyone,

 

Ive got a 2000 Silverado 1500 Z71........Just noticed today driving down the highway that there is a draft coming in under the dash on the passanger side................just wondering if anyone knows where it might be coming in from and how to seal it up....

 

Than ks.....

There is a TSB on this. It is very common, mine does it. It's kind of a complicated thing to fix. Basically it involves resealing the fan box for HVAC system.
