Anybody have suggestions for defrosting rear and side windows? There used to be a stick-on electric defroster like the ones that come on new cars but I don't see them available anywhere anymore (maybe they didn't work). Thanks.

Quick search found those at jcwhitney, if you search for defrost you'll get more items as well.

I bought a rear window "defogger" for my son's '74 Dart Sport from someone here or on another board. They were available on some models. It does not have a heating element, but relies on the cabin temperature and simply is a fan that blows air through a plenum mounted in the package tray. I don't know what to tell you about the side windows.

Seems like someone else here (Dart 270 was it you?) had one for sale.

I have always found a nicely folded cloth rag to work wonders when trying to defog the windows. That and leaving the side window down about 1/2" keeps the rear window clear when going down the road.

Didn't the stock rear defroster have a mini heater core in it that got plumbed inline with the heater core up front? I recall reading in the manual that cars with rear defrost had increased coolant capacity.

Try rain-x antifog on the inside and regular rain-x on the outside, that works decently as well.

My '75 Valiant came with a defogger, which was nothing more than a fan that blew on the rear window. They also offered a defroster, which was a heating element grid bonded to the glass. I never saw a defogger with a heating element, but I'm not saying they didn't make one.

The defogger was pretty much useless in cold weather, but during warm, damp weather it kept the glass clean.

I have never used the aftermarket defrosters, but I have seen them installed. The heating elements are very thick and reduce vision substantially. They also stick out from the glass and are easily snagged. I wouldn't waste my money and time on them, but to each his own.

The defogger blower and the defrost grid were never offered together. The defrost grid option used a 65 amp alternator on the 1975 Valiant/Dart cars and a heavier wire from the alternator to the battery.

I happen to have this main wire and the wiring and special switch/relay/timer for the defrost grid window (from a salvage yard car, never seen one before nor since). I tossed the window later because it had several of the grid strips scratched. I talked to an auto glass place several years ago and they can put the defrost grid on a window. They sort of "ironed" it on with heat I was told.

You used to be able to get the "peel and stick" variety at auto parts stores some years ago. I had one once. It worked great. However it got damaged when I had to remove the rear window to repair a water leak.
If you find the peel and stick kind, it is very important to follow the directions, be sure the window is CLEAN so it sticks, and shine up the connector strips to remove the tarnish before installing them.
