Booster fan to increase air flow to rear seats.
Step 1: Parts Needed
80mm PC fan, I used a spare one I had but the higher CFM the better.
12 Volt cell phone car charger.
A few pigtails for connecting charger to fan.
One plastic cable strap.
Solder and Soldering Iron.
Electrical tape or heat shrink tubing.
Step 2: Cut Wires and Solder Pigtails
Cut wires to length and solder pigtail connectors
Step 3: Install Holding Strap
Install plastic cable strap and secure with electrical tape.
Step 4: Installation on Front Vents
Slide plastic strap into vent opening and push fan up against vent. Adjust to direct air flow to right areas.
Step 5: Installation on Rear Seat Vents
Same as step above, depending on size of vent you might need to rotate by 90deg to fit into fin openings. Plug into 12volt lighter socket and enjoy!
