Based on the TSB, I have to replace the pump valve unit as randomly with the a/c ON, hot air blows from the outside vents and cold air comes from
the center vents.
My car is out of warranty with only 42K miles.
Dealer wants like $600 to do this job.
I bought the part for $271 and was looking to install it but need some help
in installing this. I have worked to MBs and BMWs.
Where is this valve located exactly?
If anyone has replaced this before, any guidance would be great.
