The heater will not turn off, cannot change temp setting, or fan speed. Is this a simple repair or will I need to a shop?

Without knowing the cause it woon't be possible to recommend any rectification methods.

Get a scan done to check for trouble codes.

Which module did you replace?
Was the blower control unit tested for shorting?
