Front Seat Pads/Valances & Heating, 2007/From: 08/02/2006; With Bucket Front Seats, With Temp Control Passenger Seat, With Temp Control Drivers Seat

There is an upper and lower heater fan assembly.The part number you gave is just the lower.
BUT.......
There is a control module also, part #9U5Z-14C724-B (old part # 7L1Z-14C724-C ) so it get confusing on what part you need.

What numbers are on the part in the vehicle or going by the diagram what part do you need?
