A car air conditioner may smell like sewer due to mold or mildew growth in the evaporator core or drain pan, where moisture can accumulate. This stagnant water can create a breeding ground for bacteria, leading to unpleasant odors. Additionally, a clogged drain line can trap water, exacerbating the problem. Regular maintenance, including cleaning the system and using a disinfectant, can help prevent these smells.

It could be that the condesate drain line has been connected to the wastewater/blackwater stack.

If dry, sewer gasses are no longer blocked by the hydraulic seal... resulting in a nasty smell when the unit is turned on and the fan kicks in. Just a thought.
