I have a 2007 lincoln town car (signature limited). My problem is that when I have the dual temp on A/C and set to cold, I have cold air blowing out the right (passenger side) vents, but very hot air blowing out the left (drivers side) vents. This also happens in the winter time when its cold outside (warm on passenger side and cold on drivers).

please help.

you have I thing 2 blend door motors on that car. Sounds like one of them is bad. You can try to run a EATC diag, but I am n9ot sure of your configurations of buttons on the face. Can you post a picture of the face of the unit?

Some new cars have a Dual climate control valve (DCCV) that locks up!
