Heat Problem

[02silveradols]

I just picked up my new (well new to me) truck last night. I noticed that the passenger side is always blowing hot air out of the two vents no matter what I set the temp to. The drivers side is fine. It has the dual climate digital HVAC system in it. Any help would be great. Thanks Its a 04 silverado.

Sorry, no help from me. I have a Work Truck. One heater. One system. All works fine.

 

Those fancy trucks with dual this and dual that, well, just more things to go wrong.

 

But as a guess, there are valves/baffles/ducts and one might be stuck. Has anyone previously taken apart the dash? How many miles on truck? What year?

 

Good Luck.

 

I hope someone can provide a more definitive answer.
