Lincoln Repair Questions? Ask a Mechanic for Answers ASAP
are the hoses going into the heater core both hot?
yep going over the system and symptom tests
so you changed the dual coolant control valve?
what engine do you have, 3.0 or 3.9?
can you hear the blend door actauator when you switch back and forth in temp?
did you bleed the system of air?
we need to run a self test on the auto climate control system
you might have a bad actuator
press the off and floor buttons at the same time and then auto within 2 seconds
no codes and all segments will light
it is on the passenger side of radiator
been a few months since I did one, it did set a code
lets check for codes, might have a bad sensor
ok, air bound could be the issue. sometimes it takes time
the DCCV valve is a very common failure
dealers use a vacuum system to flush and we use it to fill systems too.
you can raise the nose of the vehicle and force the air towards the reservoir. Running it up around 2k and watching the temp will work too.
just have to watch the temp and sometimes shut it down and wait
