Response to AC on FB site

I don't have a FB account so I hope the person that has questions on this AC unit might visit this site.
I strongly suggest buying this system at a junk yard so you get everything you need. Getting just the unit from sites like ebay will leave you short of items you need for it to work.

Items not included with an ebay purchase that are needed are the heater and AC manifolds that bolt the lines up to the unit and you'll need stub outs of the lines so you have something to attach too. Lines going into the unit are unique.
Getting the Mounting bracket for the unit will make the install easier. You will need the ignition switch with the key.( It contains the CAN network for the unit to work) You'll need the control panel with the wiring harness.
Getting these items separately will be costly. The ignition switch with the key was the hardest thing for me to find. Apparently they are in high demand and can be very expensive if bought through a third party. At the yards here the cost is only $10 if you pull it yourself.

I also modified the outlet so it was angled more of a straight up angle to line up with the vent manifold to the dash.
The expansion valve that I used came out of a 1999 forester.

Feel free to post this on the FB site

If I think of anything else Thats needed I'll post it.

There is still some miss information on the west coast sterling FB site about this unit.

The system uses an electronic speed control for fan speeds, Its a variable speed control not a low, med, high speed control as in the resistor style systems.
Without the control panel and the ignition switch the fan speed control wont work. Trust me I tried.
I suppose you could install the resistor style speed control, you'll still need the oem control panel which controls the diverter flap for the direction of the air along with the sensors in the unit, then you'll need a separate switch to control the fan speed. Thats just making things more complicated and cluttered.

I tried to make this as clear as possible as to what is needed for the system to work but some people still think by just installing this unit and installing lines, compressor, condenser, drier the system will work.
I also installed a Subaru evaporator temperature sensor so there would be no problems with the ECM when the AC kicked on.

Also something to point out to all of the VW members out there, They make electric compressors so that eliminates the issue of how to mount the compressor to your VW engine

Just an example, many more are out there

It’s so cool that they have those 12v compressors now. Twenty years ago when I was trying to solve the AC dilemma for one of my project cars I was searching like crazy for an electric compressor and wondering why none existed. The growing popularity of electric cars are of course what tipped the scales towards companies starting to make affordable, propose-built 12v AC compressors. It’s weird to think how I might have solved the issue had those existed back then. What an incredibly simple solution.

If you piece it together

Unit

Control Panel (missing covers on the control tab)

Ignition switch (No key and no harness)

Heater Duo Valve

Price +- $423
Like I said earlier getting all this together at the yard was around $60.
They sold it as an under the dash AC unit.
Still need to get a key made which wont be cheap because of the type.
In the yards I say plenty of ignition switches but all the keys were missing.

If I remember anything else I'll update this.

If you don't get the ignition with the key, getting them separately the key will have to be programed to work. Not sure how much that would cost but doing a search prices can go as high as $200. Not sure if that includes the cost of the key.
