Lexus says I need this replaced and it will cost $3895. Well I need A/C...but no way am I paying this.
It's a 2007 IS250. Any ideas?
They also say i need a new intake manifold and that will be $1045. Because it shows the obdii code P2006 and throws out the check engine and vsc lights.

 

So I guess this is the entire A/C and heater assembly. I think it is $1795 to replace. If I really needed to, could I replace this myself? Is this a possibility?

These are the codes that the Lexus tech said he got:
B1421, B1424, B1441, B1442, AND B1446

And apparently code P2006 pops up. He says I need to replace the lower intake manifold

 

Any advice at all?

 

Well I'm gonna pick it up tomorrow. Spray down the MAF sensor, throttle bottle, and intake and see what happens. Look at the A/c some more. idk what else to do
