Ok I research and see that this is a problem with a lot of 2004 rx-8's, where can I find after market replacements.

 

Paul at Mazmart.

 

I had to bite the bullet and buy it from the stealership

 

the **** itself is not that expensive, like 20-30 bux ? (well its not really cheap for a plastic ****, but its cheaper than the whole HVAC unit)

but if its the HVAC control unit ... then its gonna cost couple hundred.

Oh yes go find the parts @ Mazmart. They might have some used one that you can get for cheap.

 

no aftermarket that i know of, but mazmart (a great sponsor of this site) should have some that you could buy.
