12' Silverado Defrost

[Jason24]

Problem #1 with the new truck
Driver side windshield defrost seems to work just fine, but the passenger side does not. Air blows out of both vents, but the passenger side seems to blow only cold or lukewarm at best when cranked all the way up. I have the digital automatic climate control. Are the blend doors for defrost separate for driver and passenger?

See if there is a separate temp setting for the passenger. (I would think there is on an LT with digital climate)

There are separate temp. controls for driver and passenger, but I'm pretty sure the passenger one deactivates in defrost mode. I will double check though.

I haven't personally checked yet, but according to the manual:

The passenger temperature control
cannot be activated while in
defrost mode. If the PASS button is
pressed, the button indicator flashes
three times and will not work. If the
passenger temperature buttons are
adjusted, the driver temperature
indicator changes. The passenger
temperature will not be displayed.

I haven't personally checked yet, but according to the manual:

Have you tried increasing the temp of the passenger side prior to going in to defrost mode?
By those instructions, it sounds like you just can't make a change to the pass temp while in defrost.

No go under that circumstance either. The problem does however seem to be somewhat intermittent as it worked just fine this morning. I called the dealer and they are going to check it. I just hope the whole dash doesn't need to be ripped out of it.
