    so as you know I took some time off of my project. one idea I came up with for a defroster with heat was a 12 volt hair drier for rv people & connect it to the vent to the windshield. the move the switches to the dash. what do you guys think ?

    I think you will be very disappointed with how well they work. Suppose you hook it up to and it draws 20 amps. Then it would be producing 20×12 or 240 watts of heat. This would be approx 1/7th of the heat of your home hair dryer. They kinda work, a little bit. Very little.

    Take one of these and toss it on top of the dash when you need it.

    I just have a bower to circulate air to the defroster vents.
    No added heating element.

    Something similar to this: http://www.westmarine.com/buy/rule-industries–waterproof-in-line-blowers–P012_362_001_002

    The builder of my VW-based car had tried to mate a hair-dryer hose to the VW heater hoses from the engine and thence to the defroster unit.  When I got it, the defroster motor would run but I couldn’t tell any heat at all was coming out … and he didn’t install side curtains, either.  I had to wonder, “What was he thinking?”  Heck, I had a stock 71 Karmann Ghia in college and it had a “real” VW defroster with “real” hoses and actual windows that closed, and I remember always taking an ice scraper along to scrape the ice off the INSIDE of the windshield.  So if your TDr is VW-based, I wouldn’t place a lot of hope in the effectiveness of your defroster plans.

    Now that I am living in Vegas and rebuilding my TDr, I took out the VW heater and defroster altogether and like the original builder, I’m skipping the side curtains, too.  This is going to be strictly a fair-weather vehicle but that pretty much accounts for 300 days a year here anyway.  Hence the defroster motor is available if you want to try.  Good luck making it effective!

    Crash…is your TDr VW based? If yes, are the heat exchangers hooked up?

    I’ve driven my TDr well into the winter. I can’t open up the VW heat all the way. It gets too hot.

    But I’m trying to understand what you are really looking for.

    You started the thread asking about a defroster. And it seems to have segued into heat in general.

    When operating properly, the VW heat worked for a Beetle. The defrosters, worked well enough to keep the windshield fog free, but would not melt ice on the outside.

    Our passenger compartments are about half the size of a Beetle. And we’re sitting right on top of the heat ducts.

    It’s been my experience that the VW heat works fine for a TDr

    yea its a vw pan. the heat should not be a problem. but the defrost is only a hole with no fan or ductwork

    I’m gonna stick with my original story. 😉

    I’ve been okay with no additional heating element in the defroster duct work.

    Well, not many foggy bebop’n days out here but back in Fort Worth I used ‘Rain-X’ on the outside of the windshield and wiped and buffed ‘Never-Fog’ on the inside of the glass. I seldom went bebop’n on rainy days and if I needed more than that I just kept a cotton towel in the passenger door pocket for excessively foggy days.  YES, I had an MGB too. liscensed “B-MUSED” – B – Bopp’in  Get it?

    Randy in Chandler Arizona, great B-bopp'in teritory. I must have the only one in the country made by Rich Industries in Port Elizabeth, South Africa, on a 1986 Ford Cortina (english ford escort) It's a 1600cc straight four cylinder front engne, 4 speed, changed from right side driver to left side with several shafts and u-joints. BEBOP because I once had an MGB with license plate MG-BEPOP in Virginia.
