 Posted: Wed Jul 19, 2006 7:51 pm Post subject: Ambulance fan question |
 |
|
| I just received my set of ambulance fans from "the land down under" and I have a question. Where does the fan switch mount? I am putting them in my 69 Westy and I don't know where the swith is usually mounted. I imagine that the dash has a factory hole in it somewhere behind the padded part of the dash, but where? If anybody has any pictures of their switch location, that would be great.... Thanks! |

Next to the headlight switch.

| In the above picture you can just bearly see the hole for the swith. It's covered over by the vinyl of the dash. The metal underneath already has the opening drilled. (thanks sluggo!) |

They are in-duct fans that let you get/keep air circulating when you are standing still. They also help get the windows defrosted quickly on those chilly mornings. (from what I hear... this is my first set.)
I picked up the fans from a guy who advertises here on The Samba. Do a search for ambulance fans in the classifieds, and you'll find them. He still has a set listed the last time I looked.
Liveonjg,
How many speeds do your fans have, I think I have two sppeds with mine... are they all the same? |

|
|
Several years ago, I found a pair of 1968~79 VW Type 2, two-speed, intra-duct, ventilation booster fans (aka Ambulance Fans), in the autojumble, at the Essex VW Club show, at Dunton, Essex, England.
Initially the vendor asked £15 for them, but I haggled and finally got them for £10, albeit lacking the matching double-throw, rotary switch. fortunately, one can also use the switch part, of a 1968~72 VW Type 2, dashboard-mounted windshield wiper cum washer switch.
I wired them up using a pair of heater-lever, white nylon spacers, with ¼ inch ground (i.e. earth) terminal, so that the fans only work, when my main ventilation flaps, have been opened by the blue-knobbed, ventilation control levers.
My fan switch, is positioned on the passenger side of the heater & ventilation control levers, because I felt it more important that my switches for the heated rear window, rear-window wiper & washers, rear fog lamps, front fog lamps, front auxiliary driving lights and front headlamps, be close to hand.
Don't forget, that if you buy second-hand fans & switch from Australia or South Africa, etc, the wiring harness, will be for a right-hand drive vehicle.
Regards.

It helps to open the cool air vents (blue lever) to increase the air flow.

Two speeds, I think that's how they all are.
Good luck with the install.

And noise level!

So by just switching right for left, problem solved right? I don't see how that matters....  or does it?  |

It probably doesn't matter a great deal! If one wishes to mount the switch on driver's side, when transplanting the ventilation booster fans & dashboard-mounted switch (particularly the switch!), from a right-hand drive vehicle to a left-hand drive vehicle, then the cables to the switch might be too short or even too long! I suspect it might be more of a problem, transplanting from a left-hand drive vehicle, to one of right-hand drive.
It all depends upon the configuration of the wiring harness, which I suspect might depend mostly on the live supply cable, from the fuse, to the switch; the fuse cum relay box being on the left-hand side, on the opposite side to the driving position, in my British specification, 1973 VW "1600" Type 2 Westfalia Continental campervan.
Anyway, one can easily make up one's own wiring harness, using multi-way connector blocks (I salvaged several types from the car breaker's yard), appropriate gauge cables of yellow, black/white and black/green insulation colours, the last two of which, are of the same gauge and colour as the turn-signals (i.e. direction indicators).
I used some brown/green cable (ex Austin Montego or Austin Maestro), for the ground (i.e. earth) connections, from the fan motors, to the ventilation-lever spacer's ground (i.e. earth) terminals.
In addition to the pair of early-model, 1968~79 VW Type 2, intra-duct, ventilation booster fans, without dashboard switch, I bought at the Essex VW Club show, I also obtained three (a pair, plus one spare) late-model, 1968~79 VW Type 2, intra-duct, ventilation booster fans, with matching dashboard switch and wiring harness, by virtue of an advertisement, I had placed in the WANTED section, of VW Motoring magazine. These fans, which were said to have originated from a left-hand drive, German specification, VW Type 2 Double-Cab Pickup, were somewhat more expensive, priced at £60 including shipping.

While parting out a Canadian 74 Kombi several years back, I discovered it had a set of the fresh air fans which are now installed in my 74. They do help out defrosting the windshield in the winter and help moving a little cooling air in the summer but they are a bit noisy. Good conversation piece at campouts and shows.

Yes, these ventilation booster fans, can certainly be quite a good conversation piece, because the majority of 1968~79 VW Type 2 owners, in Great Britain, the USA etc, have never come across these components.
One of my other interesting conversation pieces, is my cross-over-pantograph, rear-window wiper & washer system, which clears more than half the total window area. Even though I say it myself, the installation is so tidy, it could be mistaken for a Volkswagen, factory-fitted system.
In fact, the wiper is a relatively simple adaptation, of the stock, factory-fitted system, as found on the Vauxhall Chevette (equivalent to the Opel Kadett C, Holden Gemini, Isuzu Gemini, Daewoo Maepsey, Chevrolet Chevette, Pontiac T1000, etc) station wagon & Vauxhall Astra Mk. 1 station wagon, which I salvaged from a local car breaker's yard.
Swedish made, SWW wash-wiper blades, with hollow blade rubbers, fed by a flexible rubber hose, are amazingly effective too.
What other interesting conversation pieces, have you discovered?
Regards.

I just put the fans in..... whew! My westy was obviously in an accident at one opoint in it's life because the tubes were a bit oblonged, and getting the fans to fit and spin freely wasn't an easy task, I also had to re-work the flanges to make the new covers work. (alot of bondo "rat-tails" back there too)
The wiring harness was an issue. I will most likely re-wire the whole harness to make it a clean install. ( I'll do this when I strip the van for paint in the spring, right now I want to drive it!)
I had to extent (double-back) the hot lead. Not a big deal, but I would like it to look better.....
It took some tapping to get the fans to run quietly.... and they really don't make noise now, all I hear is the air moving, with perhaps a quiet hum from the motors. The rest of the wiring looks like hell..... I pulled the old radio and I am putting my 8-track in now...... Back to it!
Thanks guys, I'll post pictures of the install next! |

If this works. . . . it did not work for you because of the difference in picture addresses.here is an example of the nomenclature in the link. *https://www.thesamba.com/vw/gallery/pix/291964.jpg*
