Does anyone know the part number, manufacturer, etc. of the HVAC circuit board? (I cracked my LCD doing LED swap) I am going to look around and see if I can find the manufacturer or what not of it and possibly get it direct or some nonsense I dunno....Before I go buying a whole new unit, junk yard, etc.

 

Not possible to buy another LCD, you will have to purchase a replacement HVAC from a junk yard or ebay. They go for $60-$100ea. Or toyota wants $450+

 

What if I go directly through Denzo somehow?

 

Not gonna happen, sorry!

 

and why is that?

 

Try it and see. Denso will not sell an eletrical component such as a custom made LCD screen specified specifically for toyota to the public.
