Please help me on the driver side is blowing really cold and the passenger side is blowing really hot while the a c is turn on. This happen to anybody?

 

You have to change out your servo motors bro. Look it up, read on those topics. It's located in the passenger side, in the dash compartment. Behind the plastic components. There's allot of threads with pics and everything on how to do this. Look it up: SERVO MOTORS. Also, my recommendation, change both with OEM Lexus. It'll be the best option. I had to as well. If you sign up on www.sewellparts.com and link your CL account to it, you'll get GREAT discounts... on everything. Hope this helped bud. Good luck & I hope your problem is resolved!!
