The hoses from the compresser seem to be backwards.
The big hose running to the accumulater is hot and the small one is cold. this is backwards from any ac ive ever seen. the system is holding freon and the compresser kicks on fine. still no cold air. what could b the problem?

by that can, with hose. and gauge. see connnector on hose of can. see it? now on car there are 2 pipes, and one has large conn, and one is small only 1 fits hose. easy huh? us the one that fits. do not run the compression if there is no A/C, you can burn it up. the Freon has PAG oil that must he present , if missing BOOM. BIG MONEY!
Has two cans of charger, compresser running, the bigger of the two AC hoses cold while charging nothing inside car, then hose got hot and still nothing inside car. It's been charged for month tried daily, seems to be no links. Manuel has no information. Anyone know anything to try? Thanks for your help.
Both of the hoses at the heater core should be hot. If one is cold the heater core is plugged.
You can think of it this way. If the thermostat was stuck closed and you checked the upper and lower radiator hoses with the engine hot the upper hose would be hot and the lower hose would be cool because there is no flow. If you check the hoses with a properly working t-stat both hoses will be hot when the t-stat is open and coolant is flowing.
Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
It is very possible that there is air in the Heater hoses and it needs to be "Burped". With the engine COLD, remove the radiator cap and locate the Heater core hoses (there will be 2 hoses close together - In and a out). It is also possible the thermostat could be installed backwards.
it could be a slight leak from the heater matrix (check for damp in the passanger foot well) its self or the thermostat may be sticking this may cause the bottom hose to stay cold. you could try removing the thermostat and running it without it and then putting a rad weld in the coolant system to seal the matrix.
check under hood for the two hoses at firewall leading to heater core with engine running and warm carefully feel each hose if one hose is hot and one cold or cooler then you have a plugged heater core if both hoses are hot check to make sure hot cold selector is moving door if they seem ok reply and we can perform further tests
hope this helps plz vote or comment reply if need more help
RADIATOR fluid does not evaporates over summer or winter as it should stay in the cooling system and just go around and around so if you are loosing fluid then you have a LEAK and it might be when hot/ when cold /when driving , so tie a plastic bag over the out let pipe on the over flow bottle and see if you get any water in it over 2 weeks if yes then you could have a head problem,water pump problem,hose or hose clip problem leaking water but you wont see it ,it could also be the thermostat which needs changing to winter one,could be water pump or core plug leaking either hot or cold ,its a big job to find a small leak ,but a small job to find a big leak,but a few early Camrys had slight thermostat housing water leaks but dried up quick when you stoped, but another way to do it is to add a blue or a green die into the water system and run it for a week then check it over and you will see the stain...
Have a goodday..
it seems as if there is a clog in the radiator, flush out coolant system and see if this helps.usually when top hose is hot and bottom hose is cold there is a clog somewhere in system. check radiator and make sure coolant is circulating. hope this helps carl,
