Question about 2002 Chevrolet Silverado 1500HD

1 Answer

Heater blows cold on one side of dual system.

My heater started blowing cold air this morning on only the driver's side. It's still blowing warm on the passenger side. I have the dual air/heat temperature control with one fan for both. Can you tell me what part has gone out and is this something I can do myself?

    I have a 2003 Cadillac Deville with the dual air/heater system. The driver side blows out cold air but the passenger side blows out cold. Even if I put the system on defrost it does the same thing. What problem am I having and what can be done to solve it?
