It is deff in fact your ac compressor. Reason being the ac compressor operates on defrost to remove moisture in your truck. So it being, if you had you defrost on, your compressor will run.

Your A/C compressor is engaged in EVERY position except vent only and feet only... Every other setting calls for the compressor. So, if you had the defrost on , your compressor would be cycling.

When the compressor clicks on it can be pretty loud if you're standing in the right spot.
