1 Answer

Could be 2 things --- first check coolant level --- if coolant is low or got an air pocket in it it will make climate control act goofy ---- either hot or cold air ( in your case both ///// if coolant level is correct and nobody had messed with it it is the AC mixing valve ( located on passenger side of radiator ( V^ will have 3 lines and V8 has 5 --- There are 2 solenoids on top and this is what controls mixture of hot water to ac to control climate control .

My 2004 lincoln ls air conditioner is blowing hot air. The ac filter light is on and so is the check engine light. Please help. What could be the problem? Does the system just need to be charged?

Your issues can not be answered easily or definitively, as the LS is very complex and all electronic.
I would need the stored codes,that set the check light (MIL Light)
You can cycle the right dash display to ACFilter and Reset,with the top row of buttons,in center of dash. There is no sensor on the Cabin Filter. All the dash displays, are just reminders,you can set any way you want, % wise.

Possible issues--Fuses
-- Coolant control valve
--DATC module

You will need a really good Technician,not a general mechanic, to diagnose your problem
You need to put a professional scanner on it, to start any diagnostic work
