Heater Cable Blues

Hi, I’m attempting to get my heater working- tall order I know! (Currently no air flow hot or cold through dash vents)

Checked all the obvious things and the last to look at was the cables that lead from the dash controls. Think I’ve found the issue. My van is Californian import with UK dash. Cables are connected at the flaps near the heat exchangers. Cables not connected at the leaver end dash end!

From my reckoning I’ve got the cable still coming through to the dash on the Californian side. Think I can see the cable adjuster.

See pic, would you agree with this?

Oh, crap

If this is the case, looks like quite a job to sort this properly. So would anyone recommend permanently, somehow forcing the flaps open? They open manually easily, but of course spring back closed

 

Fit a propex and your blues will go away in every sense.
I fitted new ( repro )heat exchanges, concertina pipes and heater pods.
No leaks/ blockages...even when pods fastened open heat was nothing to write home about.

 

The thing in your pic is the actuator rod for the front fresh air flaps, not the heating. The heater cables should come up through the front valance behind the kick panels.

 

Shouldn’t the actuator rod for the fresh air and the heater control cables be on the same side of the dash though?

So the 3 leavers on my van are on RHS with nothing connected, while the actuator rod is coming through on LHS just dangling behind the glove compartment

As I’ve RHD vehicle that used to be LHD, is that the issue?

 

Yes, but you could take it to pieces and reassemble for RHD no doubt.
The cables will be wrong too if they are for US bus.

 

Sounds like it. Might be worth taking the front flaps off to see if you can reposition the actuator rod on the other side (assuming you’ve got an appropriate hole in the front panel).

 

Best thing is to seal them shut anyway.

 

I always regret the first thing I did to my bus was to bin the probably original but a bit rusty heat exchangers.

I had not yet learned that unless an original part comes off as a bucket of rust, you keep it and put it back on in 6 months after fixing it ..fool !.


With aftermarket heat exchangers, I find they eventually raise the temperature in the bus by 10 degrees C...

 

Doesn’t look like I have the ‘appropriate hole’

 

oh! I’ve just tie wrapped them open. See what happens.
When I’m allowed to drive it!

 

They are new German made none originals, fitted last autumn when I got the new top end.

Plus 10C I dream of this. Tropical

 

The oval hole that the rubber bellows goes through?
