Chevy silverado heater stinks

I have a 04 Chevy 2500HD with the 8.1 and everytime you start it up the AC/heater unit blows out air that smells like burnt eletrical, it use to do it only when it was cold out but now it does it all the time.

There is a fan control module mounted in the air plenum that is known for going bad.Check the connector where it plug's in under the case below the glove box for a burnt connection.Usually the connectors will melt but it can still be bad where it goe's into case.It need's airflow to cool the resistor,s for the differant blower speeds.

One side air blows cold one side blows hot


GM has a known problem with the electric actuators that operate the blend and temperature doors in the HVAC system. There are 4 or 5 of these in the typical system. Any can start sticking or binding and cause this problem. Sometimes they can be cleaned, or they might need to be replaced. Sometimes resetting the HVAC system controller by disconnecting the battery for 10 minutes, then reconnecting it, will correct the problem.
