I can't get anything to my heater fan. I have went through the bentley and have chased some wires, but I need to find a couple plug ins. Or need to know if they are supposed to not be plugged in. I have one that has some fat red wires going into it and a brown that is a 3 wire connector that is in the harness=I need to find where that plugs in.
I also have a white connector that has a top row and bottom row with around 16 pins total in the harness I can't find a spot for.
If nothing else I will get pics tonight, but would rather have you guys tell me how to put humpty back together again :D

Bump.
I didnt' get over there as I had to babysit. Any help would be great. Pics are especially useful.

What year is this bad boy? What electric system does it have? I'll see if I can dig something up for you. :)
Edit: AC or not?

86
I think it is CE2, but not sure. Here is a pick, it has a clock no tach.

A/C it has but not all there yet. It was originally a N/A 1.6L now Turbo.
It is the car in my build thread. I have to get it back together soon and wiring isn't my strong suit.

The 16 pin connector is your problem. It goes plug into it's mate under the dash , above your right leg ,just below and left of the HVAC controls. When all the taxis here were all those late 80's mk3's , because they had the fan on 24/7 for 3 years [ 3 year/ unlimited warranty ! whoo hoo!] it would burn that connector where the fan wire was .
-
Cool.
I will try tonight.
You can actually see the other connector in the pic I posted. It is visually inbetween the steering wheel and the shifter. It looks identical to the cigarette lighter, but a little different.
that is the cigarette lighter connector, the other one goes into the same big loom and you can see the bottom of it going up to somewhere. ANy idea where? I can't find anything for it to go to. The white one that I will try tonight I couldn't see anything either before, but now I know where to look.
Either way pics will be taken in case I have further trouble.
-
I looked and it isn't a 16 pin, looks more like an 8. Here are 2 pics of each that I think go somewhere that I can't find.

the first 2 are the same plug and the last 2 are the same plug. I think they belong to some female and are needing connection. Help them out guys.

More and new pics of the other end, the a/c stuff.

With the last pics and these ones that is every wire that is unaccounted for in the car. Please help this diesel dubber.

I didn't get to check everything yet, but the fan works when jumped from the battery. Any suggestions welcome :D
-
its CE1.. they didnt swap to CE2 till like 87/88. and you should be counting your blessings because of it. i like the CE1 wiring so much better.

So help me out and tell me what goes where LOL
Seriously, I don't understand wiring like some of the guru's out there. I have tracked stuff down in the bentley and it just says "xx connector under dash" It never tells you where stuff goes from there in a physical location on the car and I can't find anything that those pieces connect to. I need to know where to look.

For the next time I need to search this up, that pic^ is the power for the fan. It goes in the back of the vacuum slider thingy.
My fan works now. Just needed power. Now that it spins I need a new one since the bearings sound shot in this one.
-
I thought that looked like the power plug for a heater. Not knowing your vehicle well enough to say for sure. I had my 1981 Rabbit heater apart big time a couple of weeks ago. Came out after I pulled the wiper motor and blades off. Then I could get the the motor out by sliding it over to the corner of the car well by the drain plugs and twisting it out. Runs great now that the bearings have a little lube on them. And all the leaves and branches are out of it. I took the liberty to use the shop vac on the heater core and remove years of buildup in there too. Just have to be careful around those fins.
Does your blower motor come off from the inside? Or from between the hood and the windshield?
-
My fan will come out through the inside, I think.
The plug doesn't go directly to the fan. It goes to the back of the temp selector/vent position selector thing in the dash.
-
Does that go into the back of the heater switch?
Did you get the big plug figured out? I know under the dash is a nasty place to visit but I can lay on the floorboard and get my head up in there most times. I'm kind of wiry so I may have an advantage there but mirrors and flashlights work as well. When I worked in a place that installed aftermarket A/c a palm sized mirror with the light shoved up in there was pretty valuable at times trying to get a finger on a wire that got away from me.
And did you get the green and brown wires figured out on the sensors on the flange? Looks like the two green go on the two side by side tabs and the brown wire with the black cap clips on the other single tab on top.

No idea on the wires under the hood. The white plug I believe is for cruise control and I don't have that.
I am very flexible, I just didn't know what was what. I needed someone to point me in the right direction so I didn't have to take apart the dash like I did.
I think the green wires will go onto the flange, but I have no clue where the other wires go.
-
So the multiplug wire is for cruise? I can't remember exactly what the plug looked like for the instrument cluster I had out weeks ago. Seemed like I had to squeeze a top and bottom keeper like the ones you are holding in that picture. I needed to do some work on the trip keeper but found it to be broken beyond repair so I just lubed up the main Odometer to keep it from doing that 9/10 mile clicking thing and not giving me true mileage.
I would try that brown wire on the top of that flange with the green wires. Most of the groupings on my VW are wrapped in black electric tape and that is what looks to be the same for what you have as well.
The orange cord coming up in the pic with the green wires kind of threw me for a bit. Once I got the perspective right I was, oh yea trouble light.
