Any one else had this problem. A/C started to blow hot air out of left vents and cold out of passengers side. Turn off and turned back on and air blew out of bottom. Disconnect battery, turned ac back on all was good for about 30 minutes. Started to blow cool but not cold ac. Any ideas ??

 

I had this happen on two of my IS350's. It was a known problem for the IS350 and they ended up replacing something like 5 different servo motors. The problem was intermittent for me but I didn't have any issues getting it fixed as I believe there is probably a computer code stored and probably a diagnostic they can run.

 

Just hit 10k miles in my LC and I'm now seeing the same thing. Thankfully still under warranty. When my last IS350 had this problem they replaced 7 servos. I'll be taking it in next week.

 

i think you meant now. ? (you can edit the post )

anyway, best of luck and keep us updated.

 

I’ve had to take my 2018 in twice for actuator replacements for AC failure. Nothing like starting the car during a 115 degree Arizona summer to have the HVAC blow nothing but heated air.

 

My car stopped blowing air through front vents at 24K. Was fixed under warranty. The cost was approx $1300 in parts alone.

Now the ventilation system started to have bad smell whenever I start the car.

 

North...Isn't the cabin air filter supposed to fix that?

 

i just replaced it 1k miles ago. Surprisingly, this issue didn’t exist before replacing the air filter

 

Then I would recheck the filter. Maybe you've got a bad one.........
How bad is the smell? .......Any ideas on the type or source of smell?

 

depends if he just ate a bean burrito or indian food.

 

Just got the car back from the shop. They replaced 4 servos:
PNs: 87106-11060, 11090, 11020, 11010. All have a price of $220-280 on MyLParts.com. Dealer said it was a 9 hour job and labor rate is $173/hr.
Lucky it's all under warranty.

Service rep said he believed/heard it was a heat issue as this problem is pretty common in Phoenix and was related to some lubricant or wax that melts/breaks down in the extreme heat. He said he believed that Lexus either had resolved the problem or is close to having a new design that resolves this problem.
