A/C only blows out warm air. Does not work.
A/C only blows out warm air. Does not work. My Air conditioner worked perfect yesterday. Today on my 15 minute ride to work I turned on the air and it would only blow out warm air. I got home tried to put FREEON and it would not take it.
What is the problem with my car? Why does the A/C blow out warm air?
Why does it not accepth the freeon?

Try this: Jump the wires on your low press switch and your compressor should turn on. If it turns on it when you jump the switch then your freon is low (the purpose of the low press sw), if your compressor doesnt turn on then you might have a bad sw.
Good luck!

Take it to midas and have them check it out. Its not that expensive. You may have a leak or something. In my 97 cavalier, which i sold, but it would do the same thing, blow warm air. they put freon in, and it only worked for like 2 days. there was a leak so they have to replace something in there.

What is the low pressure sw?
How do I jump the wires?
What is a bad S/W?

If the sw is bad then your compressor would never turn on no matter how much pressure you had in the line.
Now with that said, there is also a high pressure sw that does the same thing except it shuts the compressor off when there is too much pressure in the line.
I hope this helps, most of the ac problems are either not enough freon in the sys (causing the low press sw to open) which could be caused by a leak or bad switches (either hi or low)
good luck!

Another good check is to simply touch the lines. The low side (big line) should be cold and the high side (small line) should be pretty hot. You can use this test to see if there is an obstruction( ice in the lines due to too much moisture in the fluid) as well as checking to see if the compressor is pressurizing the fluid
