1992 Lexus SC300 Air Condtioner blowing cool/warm

My 1992 Lexus SC 300's AC blows cool air (NOT cold) and then gradually gets warm, then up to whatever the outside air temp is.
what is most likely wrong?

    It does this when on recirculation and/or fresh air


    All guages seem to be working - the display says "cold", "75" etc, but the air is warm


    thanks so much for responding

    the 1st thing to do is have the system charge level tested, then if that checks ok u may have a temperature control blend door problem.

My 1996 Lexus ES300 ac blows cold for a while then starts blowing warm air. Then I turn it off for a while


There are a number of possibilities.
1. If the compressor has a clutch, do you hear it engaging and disengaging?
2. The valve controlling the hot water going to the heater which mixes warm air with the cold air from the evaporator, is not working properly so it si not maintaining proper temperature.
3. THe temperature sensor that senses air temp at the intake to the AC in the cabin is defective.
4. THis is too comlicated to fix yourself, so you need to take it to an AC expert who knows this particular model.

My girlfriends 2003 beetle,s ac does not blow cold air. This happened after an issue with low coolant. Is there any connection here, or is there other potential causes?


does it blow cold ac when the car is started after sittin overnight? if it does and gradually gets warmer as the car warms up, then you may have an air bubble in your cooling system caused by the low coolant level. if it blows warm anytime, then your ac system may need to be inspected or recharged.

1992 es 300 lexus heater is blowing cold


. Yes it could. some are vacuum powered, cable powered (mechanically) or electric powered. If the valve does not open. The hot water will not get to the heater core. It could also be the thermostat not opening.

Heater blows cold air


With the car warmed up,feel the heater hoses,are they both warm/hot near the firewall in the engine compartment?If they are both warm/hot,then the heater core should have circulation through it and it may be a "blend door" issue in the heater a/c assembly.If they are not warm/hot then the heater core could be dirty and plugged up and needs to be flushed.
If the above does not help,a drain and vacuum of the cooling system and vacuum refill will remove any trapped air.
Sometimes,clamping off the top rad hose and holding the engine rpm at 2000 rpm will force trapped air out of the heater core.(Watch temp gauge when trying this)
Lastly,a NEW thermostat doesn't mean its working correctly.
