Hello i have a 2002 lexus rx300 AWD and where i live its starting to get hot my a/c is cold but i want it colder my freon is full so is my coolant my a/c compressor is working perfect so are my cooling fans i wanted to try and add another cooling fan to my a/c condensor and see if that would help any ideas...and if so could someone help me mock up the diagram for it thanks alot. ~Anthony

 

Most of the time it is airflow or rather the lack of it, that creates a demand for a lower temperature. Check out the aircon filter , the ducting, the vents etc. for blockage. See if the cabin is" airtight" in the sense that a window isn't creeping down while driving, check if the moonroof is properly closed etc The RX's aircon is pretty effective to keep the occupants cool in extreme hot climates and it shouldn't be necessary to add fans etc.

 

+1, clean the cabin air filter.

Try cleaning the condenser to remove any bugs, and other junk!

 

Try using the recirculation mode instead of the fresh air mode.

 

I see about a 6-7 degree drop when I put it in recirc mode....

 

Thanks for all the help guy!! Just like a member said to clean all the bugs and junk from the condenser and keep the air on recirculation my a/c stays ice cold!! Even in 110+°F in heavy stop and go traffic 😎

 

I just bought a 2002 RX300. Drivers AC is nice and cold. Passenger AC not so cold. Any suggestions? Also where are the cabin air filter and condenser? My RX300 didn't come with the owners manual.

 

Open your glove box and look straight back their will be a cover you have to stick your fingers in their and pull the cover off and the filter will be right ther

 

I have a RX 2002 AWD and I notice cooling is affected by outside humidity to some extent. Today was not humid and I just about froze by the time I got to work at noon - 30 minute drive. Most days are really humid here in TN and I would have been fine. Recirc mode helps as does touching Auto button after turning temp to COLD.

 

Hmmm...my ac is cool at idle and when you go over 2k rpm's it gets ice cold no matter how humid

 

Thanks AnthonyMtz! Found the cabin air filter and it was quite dirty. Cleaned it as best I could until I can purchase a new one.

 

Not at problem glad I could help!
