I have a 2003 Lincoln LS sport V8 big engine. Not many problems until now. A/C quit this year. Compressor not clicking on. Last year I had to close the dual vent on passenger side and A/C was fine.
This year I dont hear the compressor clicking on. The air blows hot but
sometimes I can feel cooler not cold air trying to come through. I am thinking
it might involve the switch but could include that double vent not working
properly. Help !!
