Exhaust/light Unit- Exhuast stays on even when the switch is off.


I am replacing the light box in the bathroom with a exhaust/light unit.
When I hook up the unit, the exhaust runs continuously even when the switch is off. The light seems to be working fine, It turns off when I turn off the switch.
I have 3 lines coming into the Junction box.
Line 1: Has 1 black and 1 White wire
Line 2: Has 1 black and 1 white wire
Line 3: Has 1 black, 1 white and 1 Red.
Not sure if the color of the lines mean anything but Line 1 and 2 are white. Line 3 is black.
All the 3 black wires are tied together and all the 3 white wires are tied together.
The fixture has 1 blue, 1 black and 2 white wire.
I am connecting the blue to the red. The 1 back wire from the fixture is connected to the 3 back wires in the junction box. The two white wires from the fixture are connected to the 3 white wires in the junction box.
What am I doing wrong?

there is only one switch, correct?

if so, take that black fixture wire out of the black pigtail and tie it to the red wire.

the blue wire is the light which is connected to the red switched wire

the black must be the fan and by connecting to those other blacks its wired as always hot

If I understand this correctly, there will be 3 pigtails:

Pigtail 1 1 Black wire from the switch and 1 Red wire
Pigtail 2 2 hot black wires
Pigtail 3 3 white wires

The blue wire from the unit would be tied to Pigtail 1. The back wire from the unit will be tied to Pigtail 2. The two white wires from the unit will be tied to Pigtail 3.

Is that correct?
