My heater controls, are in the exact same condition. You can buy one new still for 75$ problem is removing it....what I am doing, is super gluing it back together, cutting some metal and wiring it to the housing to make a brace for the controls.

You may also want to look at my thread and redo all the foam on the flaps, since you have the box out....and also clean the heater core and evaporator.

Be careful. If the euro car did not have AC the main unit in the center and the blower will be different from an ac equipped 240. You need the center section with all the coils etc from a car that came with AC.

I can't seem to find it anywhere, at least not with the part number that is on the part (in the photo). Removing it should be a matter of grinding the rivets off with a dremel, then pop-riveting the new one back in place?

I am for sure following your thread cooljjay, and will be refoaming the flaps (great suggestion with the craft foam). What's the consensus on replacing the evaporator entirely at this stage of the game? Seems like something that is a real bear to get to...and here I am. My understanding of the heater cores is they are pretty robust, and most would not preemptively replace.

Have you looked at Dave Morrison`s thread on removing the Dash, AC/Heat unit, Evaporator etc......? This should answer a lot of your questions.

PeachPartsWiki: Replacing the A/C Evaporator

Morrison wrote a fantastic wiki on that process for sure, was the BEST of all the dash removal instructions I've found. And yeah, as I get to splitting the heater box and so on, will come in very helpful too.

Aside from finding the plastic bracket, what can anyone tell me about moving the manual system to the US spec car. I know I'll be moving the entire heater box and fan box.

Specifically, how do you wire in the manual fan control switch?

And deleting all the wiring for the vacuum switches etc. how is that best executed?

Thanks!

It is a lot of work, but I suggest an entire wire harness change. You can't go wrong this way. I am sure there are a few wire bundles that you may want to cut and splice, like the bundle going to the rear of the car. No sense replacing it if it is exactly the same. You could also solder in a multi pin connector in those places where the wiring will remain. That way just the main cabin wiring will be replaced. That is how I would do it if I were doing it for myself.....Rich

So...it's getting more ugly each day, both cars are...

The Euro brown car wire labeling project:

The US white car dash removal project:

The two hidden screws holding the center console to the dash, accessed through a switch hole, this stumped me for a bit, as it wasn't mentioned in the wiki I was using to remove the dash:

The US car with no dash: :-(

I guess this is "progress".

suginami · #39 04-01-2014, 08:27 PM

Well that's looks like fun.

cooljjay · #40 04-01-2014, 09:10 PM

It looks better when everything is out of the car

crazy4diesel · #41 04-03-2014, 09:39 PM

Today, I got all the wiring labeled and pulled away from the heater box of the US spec car. Tomorrow I'll tackle getting the heater/evaporator box out. Then I can split both boxes, and see what the condition of the evaporator and heater cores are. Stay tuned.

Help identifying these boxes please? What are they, and can I get rid of them?

charmalu · #42 04-04-2014, 02:07 AM

The left box above the Blower Motor is the "Electronic Unit for Temperature Control" the right box is "Electronic Control Unit for Blower Speed Control".

I assume they can be eliminated if changing to the manual system.

The Temp control on the manual is cranking on the 2 water Knobs for heat.
The Blower speed will be turning the Blower Knob to the desired speed.

Replace the center pods right now... with the best one you can buy...

Thanks Charlie, they are out of here then, that's a huge bundle of wires to have thinned out too.
