1998 bonneville - heater control valve

Can any tell me where the location of the heater control valve is under the dash. Is there a reference diagram showing it?

Are you talking about the 'blend door actuator'?

Are you talking about the 'blend door actuator'?

Not sure all I know is I don't get any heat and the mechanic said it was a heater control valve. I bought one was told it was located under the dash but am not sure where.

The actuator goes on top of the heater box.
