Heater and ac not working but lots of fan air. Fan working and not clogged. There was a mouse in truck for about a day and it did start a nest somewhere in ac ducts past the evaporator. Can a bad blending door create these symptoms. Compressor comes on and hoses going to heater core are hot. EVAP does not feel cold but not sure if it should.

Sounds like the temperature blend door isn't moving, get yourself a lighted bore scope to see if there's a nest stopping the door from moving.

Heat came on when I took truck out for drive. One of the lines at firewall is supposed to be cold enough to sweat. My line is just cool. I never use ac so was not watching it much. No one else ever reported this no heat/cold so should have been suspicious.
