Can a Lexus RX300 run in the summer?
I live in Austin, and I can’t ever get the car below 77 or 78 during the summer here. It sucks. My other car, a nissan, can get to 65 degrees in minutes on the hottest day of the year. I own a 2000 RX300 that is running great except I recently moved to a warmer climate and have noticed the A/C isn’t pushing out cold air.
How to fix a Lexus air conditioner problem?
The simplest fix, to improve A/C performance dramatically and get better FE, is to go to Home Depot and purchase a water flow shutoff valve to put into the hot water hose to the heater core. Turn off the how water flow and your automatic climate control will still try to use the reheat/remix mode but no airflow heating will result.
