No Heat Drivers Side. I have verified the HVAC system and all checks good except for the driver side vents blow cool and the passenger side hot on my 1999 RX300. This includes the front defrosters, the console vents and the floor. Hate to think that I have to remove the entire dash to gain access to the HVAC control box and look inside the guts, some way? and figure this one out. This is a weird one. And yes, the dealership says to bring it in get riiped for hundreds of dollars. I'm bound and determined to figure this one out. I just bought the car and don't want to have the Lexus blues.
