maybe it's low on freon or its just tooo hot out side did you make sure temp. setting is where you want it?
you would need to add freon
air conditorner doesnt blow cold air has freeon compressor doesnt kick on
An air conditioner blows out heat
Portable air conditioner will not blow cold air. What to do?
It might need to have the Freon re-charged.
If it does blow just not cold air you should see if it needs to be recharged
I had the same problem...until I had the coolant in the AC system recharged two years ago
gas leak or wrong wiring
you shold check the AC relay located near the battrey it is a comon problem with Camrys. Good luck
diagram for 1999 chev subarban air conditioner
Coming out of the vents around 43 degrees
You have to get it recharged. you have no freeon left which makes the cold air
