A/C NOT FUNCTIONING PROPERLY
A/C PRESSURES CHECKED GOOD,LOTS OF WATER DRAINING OUT OF EVAPORATOR BOX, ACTUATORS ARE WORKING ON DAMPER DOORS, CHANGES DIRECTION OUT OF DUCTS WHEN AIR FLOW IS REASSIGNED,REPLACED A-C TEMP SENSOR, STILL BLOWS HOT AIR OUT OF DUCTS..
There is an easy way to figure out if its air flaps or a/c cooling problem. If your blowing warm air/ ambient temp its an a/c cooling proglem if your blowing air hotter than ambient its a air flap problem. checked the blend air door actuators. found like its not working. hope this info helps
oh also feel the ac lines. touch the low pressure line is should be cold. if its warm then its a cooling system problem... then go on from there. isolate your problem its more cost efective that way
Had same problem recently. Ended up to be the A/C expansion valve. Cheap part, much labor. Center console has to come out. Drop steering wheel, dashboard has to come out. Expansion valve is mounted on the fire wall. But you must get at it from the drivers compartment. My problem was solved. Ah, ice cold air again. But yes, as previous post stated, feel hoses and troubleshoot/isolate the problem.
My wife's 2000 Linc LS,V6, had same problem, but mine was (1) bad thermostat, (2) worn out fan pump, these have an elec/hyd fan and a bad module that has 4 or 5 hoses connected to it and 2 relays on top that controls the heating and cooling. $1800 later fixed !!! Independent garage.
How do you fix the air flaps?
I have repaired a couple of ls's with the same problem. It is your dccv. valve. Dual climate control valve controls how much hot water goes into your heater cores and when it fails it fails open. letting all hot water from engine flow through heater cores. A/C is working but it blows hot air due to the valve failing. It is very common with the ls and it is easy to get to. Mounted on the passenger side of the radiator with two heater hoses on one side and one on the other. One screw and three hoses to take off to replace.
I have a question..have an 04 lincoln LS that barely blows cool air and no water ever drips underneath. It is loud like it's blowing hard, actually I believe it is way too loud, but the temperature never cools down unless it's cloudy or dark out. Any suggestions? I'm an amateur. I know water should be dripping if it's cooling right and there is zero.
Have a question 2003 ls air conditioning works part time and when it does it freeze you out sometime it blows out hot air and in winter whit heater it blows out cold air ! Is that a flap issue
