Windshield/Dash Fan for the HMMWV

[mgFray]

Driving yesterday I got caught in a rain storm, no big deal got a little wet. But I had to pull over due to the fogging on the inside of the glass. The fan, on high, didn't have enough airflow to keep the window clear.. (ended up clearing the window with my hand until I got somewhere I could buy some paper towels.)

I'd like to avoid this in the future, was talking to someone who was in the Army in the late 90's. They said their unit had installed dash fans from either a bus or the larger trucks (2 1/2 ton/5 ton) that they got from the motor pool and that gave them additional air flow when driving normally, as well as the ability to point it at the windshield if it started fogging up.

Does anyone have any pointers to a decent military, 24V fan and how to go about installing it? (Wiring is the one that I'm not concerned with, she said they just piggy backed off of the wiper motor circuit.)

Thanks!

Have you tried a fogless coating as well or even a Rain-X.

I've used my milwaukee 18V work fan a few times, but mostly now use the Red Dot aircon aimed forward at the windshield to keep them clear.

Federal Military Parts has some 24V fans in various colors for the HMMWV, or if you don't mind chrome that one is half the price

Looks like the actual military one is built by Maradyne. Found it a couple of places, the second link I just ordered 2 for myself from ($20 each, and $35 shipping for the pair)

Federal is out of the box with pricing as they just resell other's products........

Fans like this are standard in Construction equipment and trucking that is 24V. Go to a real NAPA or truck pro or real hd store and they can fix you up with 24v dash fans in black or chrome.
Should also be all over epay or amazon as most non US countries construction equipment is 24v.

I would suggest a simple seperate circuit with toggle switch and in line fuse. Some come with a switch on them. Easy to run under floor mat and feed from battery box. I would not mess with wiper motor circuit, YMMV

I second what juanprado said, those contacts in the windshield frame cause enough problems without adding more current to them, shame on Federal for even suggesting it!
