    does anyone know who makes a reproduction of the
    70-78 rear defroster ???

    I cant find anything on this

    or any other model type that carried the same type rear defroster, I doubt GM made that rear defroster for he 70-78 Camaro only, Im certain they put it on other models too who would I go to for to look that up.

    Nobody reproduces them. Best bet is to watch ebay---the '70 defogger (blower) was completely different from the later years.

    GM used the same blower with the same style rectangular grill on the large Chevy's (Impala, Caprice, etc...). The Camaro blower HI/OFF/LO toggle switch is unique to our cars, you will have to get one of those from a Camaro.

    I've seen NOS kits on ebay sell for as little as $99.00...and that included all of the correct wiring, the switch. Maybe check with hoov81...he might be able to hook you up

    [​IMG] TIP: Summer is a good time to buy one...nobody thinks much about them during the hot months

    <edit> Check for units from the Chevelles and Novas too...like I said, you'll need the Camaro switch, but the blower unit is the same and looks like this:

    ^ nothing like blowing dirt air from the trunk on the rear window . they are needed in the colder climates . who drives a 30 year old car in the winter . . my 73 ws originally sold from a dealer in long beach California ( harbor Chevy ) . its in NY right now . its a high option car but it has no rear window defogger . and what CD says makes sense . if the car was destine for a socal dealer it really wouldn't need it . it does have A/C though .

    It doesn't work that way at all. The blower only recirculates the cars cabin air and is completely sealed from the inside of the trunk. Let me explain---take a look at the pic I posted above. See the round hole on the shroud? That side fits over the top of the blower wheel---that's your intake. The air exits through the other side with the "diamond" shaped hole, through the side of the grill with the tri-directional slats.

    It's not necessarily a "winter car" option either...it comes in real handy on those cooler rainy days where you're not moving fast, your breathing paired with humidity and the temps fog the glass, and it's raining hard enough that you can't roll the windows down to move air. That blower actually moves a lot of air---you will feel significant air movement up front with the blower set on high.

    ^ that's what AC is for .. nothing dehumidifies like ac . just blend a little warm air if its too cold . all i remember is that there was always a dirt spot on the window where the blower discharged on the cars ive had with them back in the day . none were camaros though .

    Do you still have any of these? I need the '70 vent. I have everything except the vent. Thanks in advance.
