I change my cabin air filter and since then when I turn my heat on high the heater core is very loud anyone experience that

 

U probably putting it back incorrectly, just open it and adjusting it. make sure the arrow facing the right direction

 

Double check your installation. Here is a DIY that you may want to visit to ensure you didn't miss anything.

 

Dont break the recirculate door!!!

 

Might be too late for that.....

thanks for all the help will try it later

 

I was thinking that too...based on the noise comment...

 

frotiss, when you turn on the car, does the A/C button flash?

 

I didn't turn it on since will do that when I get home later

 

Do you remember if you forced the door open by hand to access the cabin filter? If the door is shut; pressing the re-circulate button on/off will lift that door for you gaining access to the cabin filter. Hmm thats all I can think of that might make that noise, if its now binding...Let us know what you find!

 

The lexus dealership told me they see tons of IS cars that need a new blower motor assembly because either the door gets broken or it gets caught up and binds and breaks.

If the door happened to break, get to your dealer asap...you might get it fixed under warranty...

Its around 1200 for parts/labor for the new blower motor assembly.

 

That's not really what happens. The owner goes to change the filter, forces the door open because he didn't read the directions, and the plastic rod with the bellcrank on it breaks. AMHIK.

Then the owner stuffs the old filter back in the blower housing and claims ignorance.

It is a huge PITA to replace the whole unit, and they don't sell the door separately.

 

I own over 10 lexus I know how to handle the cabin filter my car still under warranty will take it to them

 

You own over 10 Lexus?

With warm regards kindly provide us with the information upon these autos!

Thanks and regards
