what did you do to your 914 today Options

[carr914]

I finally finished the rotisserie and took it for a spin! Time for a little work but very hard with the heat index well over a 100.

Where is Navarre?

Neat Rotisserie. FourBlades had a cool one made out of Wood. His 914 was the only one with Rust & Termites! (IMG:style_emoticons/default/biggrin.gif)

Fixed a snapped headlite pivot and drove it all day. (IMG:style_emoticons/default/piratenanner.gif)

Ugh, I need to do this too. Fresh air blower has never worked, although I got it to smoke the other day when I cleaned out the contacts on the controls real well. Debating whether I pull the fuel tank and go for it, as the car is on jackstands anyway right now. You may have inspired (or shamed) me. I don't think I have the stomach for dealing with the controls just yet though...

Nice work!

It was one of those things I never wanted to tackle. But it ended up being not as bad as I thought it would be. The cable hold down nuts and bolts are a little tight. But not too tough. CW's should cut a piece of cardboard to slip between the dash and the controls while your trying to unhook everything. (left side) Seemed like a lot of twisting and turning.

Next will be getting the lights to work. It seems I'm missing one of the bulb holders. The black/blue wire only has two bulb holders on it. There's three sockets. I'll verify on my 73 rustoration that's on the rotisserie.

I didn't even know the blower had its own indicator light (top right corner). I'll go to work it Wednesday night/Thursday.

Oh yeah, I saw a white/brown? wire that was just cut and left open. Not good on an old car. Anyone one have any ideas? Comes out of the same wrap as the switch contacts. Just a bit towards the steering wheel from those 4 or 5 wires.
I'll shoot a picture.

This is excellent info, thanks. And any pictures you have would be appreciated. Mentioning the white/brown wire is exceptionally timely. I'm doing the wiper switch conversion based on this (EV Wiper Hack) and he mentions that there is "conveniently" an unused wire that may have been meant for an electric washer pump. On my '72 that wire appeared to be brown and black, and it shows up on the '73 wiring diagram as "91." I had a thread going with HalfMoon on that yesterday. I'm going to try to find that wire today. So, three reasons to pull the tank now:

1. Find that wire
2. Make installation of the new MC easier when it comes
3. Service/fix the fresh air blower. I had heard people say this is a nightmare, so I'm glad you're having better luck!

Thanks Cary.

Got this done today! (IMG:style_emoticons/default/piratenanner.gif) I didn't do as thorough a job as Cary did, and I didn't touch the controls, but I pulled the tank, took the blower housing out, and cleaned up the motor. I wonder why it wasn't working?




And then cleaned it up. My wife, who's more creative and imaginative than I am, helped me replace the rubber that helps the baffles seal the outlets and helped me put a grille on the housing.



Dog, still recovering from ACL surgery, does not seem to care.



I put it back together and tested it. I have fresh air blowing! As a bonus, I did find the brown/black stripe wire that connects to the 5th female connection on the "J" connector for the windshield washer pump. Now just gotta hook that up. Thanks for Dave's (HalfMoon) help.

Nice job! (IMG:style_emoticons/default/beerchug.gif) That blower's a royal PITA. I had to do it to replace the wiper motor. Not fun, much cussin' helped some. Getting the cable clamp to snap in on the bottom was the worst part. I can see why that glass is empty.

Thanks! I still have to fully put it back in and connect the cable. That could be where I really need to drink - before, during, and after! (IMG:style_emoticons/default/beer3.gif)

Since you guys have a handle on these things maybe you can explain why I am unable to get my fan blowing. It only turns on when on the middle setting not low or high. Clean contacts did not change it. So I swapped the wires to see if it was the contacts or the wires. Result: only the low speed wire works no matter where it's connected. Each contact works when hooked to that wire .
So why do the other speeds not work? It must be in the fan itsself. The fan is clean no debris. I put it in 2 years ago so I know it's clean.. Could it be the fan motor? Is there a relay related to this?

I think the one in the 'BB' works on LOW and it definitely works on HIGH ... it doesn't work in the MID position. I was thinking it may be a loose wire or a bad contact (IMG:style_emoticons/default/confused24.gif)

The LOW fan position stopped working in my Tacoma and the Toyota dealer service dept said they replaced a burned-out resistor.

I haven't fully installed mine yet (and believe me, I don't have a handle on this). I did connect it to the switch and I didn't get any fan action until I put it on high. I assumed it was either dirty contacts on the low and mid speeds or that the motor is old and weak and needs a full burst of 12v to get moving. I was just happy to have the fan moving. I may look into it more...

Handle would be a stretch.
The electric fan motor has 3 different ground inputs from the dash switch. I would assume each of those has a different resistor to create a different speed. I'm going to open up the fan tomorrow and lube the inside bearing on the fan. I'll see what the motor and windings look like.

To eliminate the dash switch you should be able to apply 12volts to the power pin on the motor. Then ground out each of the pins one at a time to start each fan speed. I'll confirm tomorrow. That will let you know which area to work on. Maybe I'll attempt a video with sound tomorrow
On a positive note. You can still buy a new Bosch blower motor. With or without the impeller.

IMHO, I don't think you could really thoroughly clean the switch contacts without taking the switch apart. There was a lot of corrosion on the bottom of the fingers.

Here's what the inside of the fan looks like. I couldn't figure out how you got the motor out of the bushing, although there are four clamp springs that seem to be holding it in the housing. Those can be removed pretty easily, but I'm not sure if you have to press it out or what at that point. Mine seemed to be stuck in there pretty well, so I had to be satisfied with soaking the thing as best I could in penetrating oil and lubricant. I'd be interested in what you find and are able to do. If I had a week or more to wait to put this back in I'd do more testing and servicing before putting it back together, but I need this back on the road in the next few days as it's a daily driver.



We may have to start up a thread specifically on this....

[JoeSharp]

Installed perlon on the front of he bulkhead in the front trunk and I am still waiting for the bushings for the shift knuckle.
Found a set of rear drop links to send off up north to a teener in need.
Pay it forward.

Seeing that the pic of the fresh air fan motor only shows two terminals, it seems logical they used resistors somewhere for the LOW and MID speed control too?

The wiring diagram shows 4 wires going to the fan, 3 of them coming from the switch, but the diagram also shows a fresh air fan relay. I don't see any interconnection between the relay and the fan motor though (IMG:style_emoticons/default/unsure.gif)


Looking forward to the video (film at 11) ?

I don't have a picture of it but the power switch connects with four (I think) prong plug to the outside of the housing. Connected to that on the inside of the housing are two "spring-like" things that could be resistors used to control a voltage drop or something depending on where you have the lever positioned. I wish I had taken more time yesterday to take pictures of it and try to understand how it really works. I just put 12v on it directly to verify the motor worked. Then I put it back in the housing and connected it to the four prong plug. I got nothing on low and mid but lots of air on high.

Yup, it'll be interesting to see what he has...

(IMG:style_emoticons/default/driving.gif) to work today!! One of the last super nice days here, weather wise....so: (IMG:style_emoticons/default/driving.gif)

I spent all day on 1! 3 more to go- it's a bit of a taping nightmare after you clean & scuff the centers. Then about 3 coats of base & 3 coats of clear. After that I polished the hell out of the rim & washed it all over again.
