My ac started blowing warm air so i got on the roof and noticed the fan wasnt turning.i tapped on it and it began to spin again,but after awhile i noticed it was blowing warm air in the house again so i went back up on the roof and noticed the fan not turning..i open up the panel and felt the fan motor and it was very hot. then after i let it sit for awhile ,turned on the ac it beagn to work again..im pretty sure the fan motor is dead but thought id check

Re: ac not working
You are right the fan is going out. When you change it out be sure to replace the capacitor. This is something you can do it is not easy but no way hard either. If you have any questions when the time comes get back with me and be glad to advise. ken

Does the fan blow warm air or is there no fan working at all? If blowing warm air, suspect a low AC freon charge. If not blowing any air, suspect a blower fan/resistor/wiring issue. You can try slapping the glove box area with the palm of you hand while the fan is turned on to see if it will start working again. If it does, the fan motor will need to be replaced. If still not working, electrical diagnostics will be required
Quite possibly a fuse or relay for the interior cabin fan (heat and cool) has failed. Search for "location of fuses for 2007 corolla" to find out where they're located, and to find a diagram. Once you've identified the fuse/relay, try replacing it. If the fan has failed, though, it might blow out again and you'll have to replace the fan motor (which is usually a TRULY pita job). Before doing that, however, make sure that the rest of the A/C system (compressor, electric radiator fans, etc.) is working properly.
I have a 2007 kia rondo.Ac was working,parked it for a year,ac wasnt working,recharged,the ac,it worked for a month,an started again,blowing hot ai.If you let it set for hour would start working...then after a few days it would only work early morning,if you dont turn ac of,then it stop working,I see the clutch isnt kicking in,ir you try an put freeon in it soon as you start putting it in it would kick on.An its full of freeon.
Make sure the condensor fan is blowing through the condensor on the roof. It sounds like the compressor is fighting high head pressures after running a bit.. After so many attepts, or if it suceeds in operating the load trips the circuit breaker.. Make sure the condensor is clean and air is passes through it from the fan. Just for clarifiication the condensor is the coil that gets hot and the evaporator is the coil yat create the cold air. Good Luck, and if you will, let me know how it turns out. Good Luck. Ned
With power off, go on roof & try spinning fan at rear through cover with a stick, or something, until fan has made 2 or 3 revolutions, then try fan mode only & see if it starts. If no luck, remove cover on roof (watch for bees & wasps) and spin fan good by hand a few times & try again, if no luck, replace fan start capacitor.
The condensor fan should be sucking air from the top and blowing it through the coils, probably a counter clockwise direction. The buzzing/humming sound is confusing to me. A humming sound sounds like a motor that can not turn over to start. A starting capacity would be needed. Just because you changed it out last year does not mean it is good. A buzzing sound sounds like a contactor problem. Contactors buzz and after a while, they will fail. In any case, you can "stick start" the condensor fan PROVIDED you are sure the ac compressor is working (this is for a short and temporary use). Also, you may have a high load duty capacitor that assists in the unit running. This will affect your condensor fan operation if it is not good. Unless you know all the components and operations of ac electrical, I would highly recommend calling out a professional.
