you must go for air conditioning service...where they will change the filter/dryer that is probably wrecked...clean the evaporator drain (do that water does not end up on your feet....and recharge the system~ ...probably still want to engage the a/c for removing condensation from the windshield regardless of the outside temp~


and evacuate the system (this is why one might not be able to perform this themselves)~


Had serviced and recharged. Working when I left but now,only work cold when it's cooler outside.

Could there be a thermostat issue?

of course...the engine operating temp is 295....if the thing is stuck open will allow the coolant to flow through the whole loop...including your heater box~ leavin you with practically NO heat~ if defrost is selected will engage the air flow to the windshield first passing through the evaporator...if plain heat...the flap will close the evaporator from the air flow circuit~ so check the operation of the Defrost vs Air pointed at your feet cable connection...if it seems loose and ineffective~ kudos on gettin' your vehicle a bit of service~!


Clean condenser coil with a garden hose and nozzle if the coil is clogged with dirt and bug not getting enough air flow across coil.


firebird338 you and I have a shop-vac...putting a hose inside the care seems a little hard to keep things dry...'specially the 'lectronics...I guess you mean once the evaprator is OUT of the car...they I agree...there are much better ways of assuring that the evaporator drain is not plugged with bugs...spiderwebs..dust...AIR BLAST...if you can find the one remedy...others are a "coat hanger" cut and straightened~ some cars actually have a rubber piece that redirects from the evap drain too~ car crazy....especially in the alberta clipper section where you might be lucky to crisp open the hose and turn the spigot from the mountian of ice that is beneath the hose bib~...but your choice this is all free advise here~


my mistake the radiator in front of the radiator...she would probably not go cold then? couldn't hurt...if your hose is not frozen shut~
