My heater now works great.
Originally it was no good at all, in heat or cooling.
I covered the air inlets in the radiator area and all is bliss!
I use it on recirculating and it's great.
Duct tape or aluminum tape for HVAC work will do.
Just remove the grille and tape.
I have a PC-625 battery , a powerhouse. You know the one, slightly larger than an iphone. I think it is 6.25 amp hours. No Problem. I'm gonna grab that cushion also. So i am up to 3 cigarette lighter plugs now - with the Dodge RAM heavy duty alternator upgrade... I'm also thinking of removing the REV 400 , replacing the stock manifold, then trying to fit an extra alternator pulley into the serpentine belt's path. If I do this correctly, my local electrical utility will have to buy back any excess power I generate but don't use. It's the law. I figure this will pay for the car over time.
They just had a grand opening for a Harbor Freight in town last week and had these in their circular. Only thing is that it is about 85 degrees here in South Florida, and only goes down to about 40 degrees for a few hours a couple of days per year so they will never sell.
Wonder if they are also selling the Solar Rope Light in Alaska in the middle of the winter when there is no sun?
