Heater er err Arghh
well, it is that time of the year when the missus would like a demister, I did not think it would be a big deal, cause when we bought the Kombi, the
system all looked intact------which it is - 11.30 last night I had a look at the cables under the dash:o WOE IS ME!! whatever held the outer cables
firm so that the levers can move the inner cables is stuffed & at the heater box end the cables look a bit loose, I think this is going to be a
miserable job, I have one question at the moment, where is the switch located that operates the blower, is it initiated by the cable lever?? |

You've just described the state of my heater cables exactly!
I've got another question to add to this one: where is the blower located? I've got a feeling mine must be missing.

THAT IS EASY!! it is dead centre above the motor at the top of the motor, looking at you when you open the lid with a duct hose coming up to it from
the tinware above each cylinder head

Well I guess that means my blower and connecting pipes are missing then. Bollox. I can see the heater box tubes where the connecting pipes attach
poking through the tin, they're covered with rubber sheet held in place with big hose clips. I guess I'll have to pop round the corner to
the spare parts place and ask them if they've got a blower and pipes handy.

Cause I don't have the car with me I can't tell you how it bolts up but it is simple & straight forward & there should be a wiring
harness plug there somewhere.
you won't get the blower set up at a spare parts store but the hosing should be easy, mine has new hosing
BUT BUT BUT it is all useless unless the cables open & shut everything correctly, & this appears to be the big job, while you are getting this
done a blower may turn up, I think a lot of the vehicles are missing the blower because people pull them out for accessibility &don't put
them back because the cables are broken or inoperative anyway & the vehicles are then sold on without the blower |

The levers for the flaps for the heater boxes are springloaded. With no cable connected, will they be open or closed?

Yeah but...........
if it is anything like a T1 the air will keep it open anyway.
When i didnt have my cables connected cause my motor was goining in and out with monotonous regularity i left the cables disconnected.
I noticed the heat comimg in - i had to actually block then closed with the old al tin and hose clamp trick

To answer the original question: Yes, the right-hand lever operates a switch when pulled all the way down, which turns the blower on.

The switch is actually part of the levers that your red plastic handle is attached to. You can hear the switch engage if you listen closely while you
pull the right-hand lever down. It ought to still have the factory wires attached.
You can see it better if you get your face right in under the dash and look up. You might need a torch! It's easy to get to if you take the
instrument panel out.
The cables can be freed up if they're stiff by disconnecting them at both ends, then carefully running some oil down the tubes while you push the
cable in and out with pliers. They should be connected back up quite firmly at the front end, using the little metal spring clamp just under the
levers. That stops the cables moving about when you operate them.
You will have to rebuild a stock Type 4 engine blower system from a wrecked Kombi I think, as there's quite a few parts involved.
Type 4 heater boxes are bigger and stronger than Beetle ones, with better flaps and a more direct operation.

OK, to try and answer a few questions, (I assume this is for a late bay!!!)
The switch for the fan is simply a contact on the end of the lever that operates the cable (under the dash). There should be a single cable
(electrical) on the braket the lever hangs off. If not the contact should be easy to spot, it's not a switch in the normal sense.
The switch operates a relay that is on the fan, powered directly from the batery (via the starter terminal).
There are two threaded nuts in the roof of the engine bay that the braket on the fan bolts to (M6 in typical VW fashion).
If the clip that holds the cables (under the dash) is stuffed, can it be re-bent to hold the cables again? If not some good STIFF wire can be bent to
replace it, but very fiddly doing it under the dash. The big thing here is that the cables must move FREELY if anything is to work. If the cables are
original they almost certainly are getting very rusty by now and need replacing. They're a pain in the A** to replace but well worth the
effort.
Also adjust the cables correctly at the rear. Too tight and you get heat coming through in summer, not good in a VW, too loose and you loose a lot of
heat when you turn them on. The 'flapper' boxes always have air blown through them, they only direct it out (over the GB) when off, or into
the cabin when on, so if there not fully on, some heat still escapes out the system. Oh, they spring to closed if there's no cable and the spring
is still intact.
Finally don't forget that all the connections are properly on, particularly from the fan (boost and the fan housing) into the heat exchanges, and
from there up to the front so you don't let any air escape, and that the tubes still have the insulation on to prevent too much heat loss on the
long trip to the front of the van.
I have spent many hours getting mine right, including the heat to both rear seats, and can't wait for winter to try them out!!
PS, in my beetle, I have never driven (at highway speeds) on the coldest winter night with the heat fully on wearing minimal gear, and the kombi seems
as good if not better.
Mind you here in Brissy that's only 2-3 degC.
Did I miss anything????

OK, thanks guy's checked it out last night in the rain with a torch, bit hard cause we have a parcel tray which has been loaded up like the
inside of a womans handbag (not my stuff) , the U shape holding the outer cable ends was missing & stiff wire inadequately used & the right
hand cable to open the flaps is snapped off at the crimp, the bracket assembly is bent-so much force has been used, the wire is coonected to the
switch, so I will have to trace it through to find the fault, not a big problem, I do have a cable clamp clip on my spare Kombi so my main problem
will be replacing/freeing the main cable, not a job to do in the rain,
AS I SEE IT with this system is that the main cables to the rear get seized up due to infrequent use, then somebody FORCES IT to break the cable/bend
the lever assembly and also the clip gets accidently dislodged/lost & the blower gets removed / chucked cause it is in the way & the cable
system is seized anyway,
shame really AND THE MORAL OF THE STORY is if you buy a Kombi & the cable works move it back & forward a few times each week to keep it free
& the whole thingshould nevere ever give any trouble. |
