Probably just low on refridgerant. Something that I doubt you will be able to check for yourself so bring it in.

If the cabin temperature sensor is disconnected the unit will just blow hot air.

I doubt anything is wrong with the system. Maybe start at the beginning and make sure the A/C button is actually pressed and turned on and you do not just have the fan on. Alot of times when there is engine work done they will disconnect the battery and everything kind of resets. My 98 LX470 still blows ice cold. Never had any A/C parts replaced.

Today I went to dealer to check it out they said there's no leak. that's good news, and they said low on freon that's good news, and they put the freon for free of charge...............

now my is350 a/c running normal again

thanks every one for advice
