Yes, the cool air is lighter than the warm air and that is why Ac's are at the top or high level of the room so in this way when the AC gives out cool air it travels down and the warm air travels upwards and the whole room gets cool quickly.
where is the location of ac blower relay
The electric heating elements are probably turned on.
I'm far from an expert but it sounds like you have a small leak or had one and the A/c just needs a recharge.
the ac stoped working and so did the heat . I changed the thermostat added freant
why does ac blow warm air? why does ac blow warm air?
Heatstrips could be on with ac
It appears that it is low on freon. Did you evacuate the system??? Take it to an a/c mechanic. could be the "head unit" or A/c contols in the dash.
It is probably too old or you could have it on the warm setting. I'm going to have to say, get a new air conditioning. MaDiSoN!!!
check the freon and cabin air filter
low freon or none
Needs a recharge
You're probably out of frion, my friend.
Sounds like your compressor is locking up.
Possibly low on refrigerant, time to call a repair man.
The blend door actuator may not be working.
It is possibly due to th compressor disconnecting itself due to overheating ("thermal overload"). It could also be a faulty thermostat.
