I have no heat- and was told I need to have the blend door replaced. on 2006 Pontiac Torrent

Is this a common problem? Should it cost $650 to replace?

Asked by for the 2006 Pontiac Torrent
If that indeed is the problem, I can see it costing that much. More than likely they have to remove most if not all or the dash to get to it.

I priced 3 mechanics around my area and it was all similar to around $900-$1100 for parts/labor.
The part itself is cheap, but the labor is very extensive.
Good Luck
