Customer Question
It's a 2002 GNC...

It's a 2002 GNC Denali that won't change from defrost to the others, I think it's the vacuum line does that sound right?

Mechanic's Assistant: What is the model of your '02 Chevy?

Denali maybe xl?

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

I'm planning on it, nothing just looking it up and it seems like that era of models have had this before and is common after so long

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just that it's stuck on defrost even when I change the switch around I gueas
