What is wrong when a 2000 Hyundai Sonata makes a hissing sound when the air conditioner is turned on and it stopped blowing cool air only warm air comes out?

Possibly the compressor has a hole in it. My 2000 Sonata had the similar problem soon within a year of purchasing. The dealership replaced under warranty.

Your air conditioner blower may have stopped working because the blower motor isn't working. You can replace the blower or replace the air conditioner.

so its not blowing at all anymore, as in no air at all? if tahts the case then how do you know its still cold. if it isn't blowing as well you may just need to change out your filter, just like in a house all cars(most)have a air conditioner filter. if its not blowing anymore at all it sounds like your compressor or your whole dam motor went out, take it to shop.

Sounds like the compressor coil is either blocked or plugged. It may also be the fan isn't blowing when the car is stopped also.

If the air conditioner is not new it could have stopped blowing cold air because of several different things, too many to list here. Here are couple of possible reasons: all the refrigerant gas has leaked away; a pump has stopped working; someone else turned the temperature control to a higher temperature...? The best advice anyone can give you is to call a licensed Heating, Ventilation and Air Conditioning (HVAC) technician to fix it for you.

Which part isn't working? Is it blowing air but it stays cold, is it not blowing at all or is it just blowing to the defroster?

air coming out of the brake lines... that is if its a truck. if you aply the parking brake.

wind stops blowing when there is no high pressure area & low pressure area- and this is possible only when earth gets equally warmed by,if the wind stopped blowing for a year then there will be no rain on that year. on other hand the production of electricity by wind power will stop.

Has the fan stopped blowing or is the air coming out cold? Need more info please, make model, year and such.

Could be anything? Best to have a pro look at it

If the compressor has stopped running altogether the AC will not work.

the unit stopped working completely - did it freeze up?

Check blower motor fuse Check to see if compressor is working

1. The shop drained the system and did not recharge it. 2. The shop accidentally disconnected the a/c clutch wire harness. 3. You may have a bad sensor or switch. 4. Nothing, it just went out.............

The air conditioner may have stopped working in a 2001 Acura TL because it needs Freon. It may also be a problem with a connection somewhere.

check and see if evaporator coil restricted, coil frozen, if not check pressures sounds like unit running but not shutting down, if coil frozen oil may be carried from compressor and leaving compressor with no lubrication repair before burning out compressor.

I'm not sure maybe there's a fan somewhere...maybe you stopped using conditioner. If you have rough, static hair, then use conditioner. I prefer Aussie conditioner but it's up to you. Conditioner gives you smooth, flat hair that's soft. Aussie conditioner comes in purple bottles. Aussie gives you soft hair after only one use! Good luck!
