Fitting Air Conditioning - how I did it

This may help other T4 owners like myself who want to have AC in their vans. I'm putting together a video series on how I did the install in my shortnose 2.5tdi - I'm guessing the process will be very similar in other models.

I opted to go a different route - mainly because I didn't want to rip out the dash and mess with the wiring, but also because AC parts from T4s are really old now and hard to come buy.

Hopefully this is useful to other T4 owners.

GREAT write-up, but I'm afraid I HATE You-Tube videos.
Have to watch gawd knows how many minutes, listening to someone who like to hear their own voice, when a couple of pages of text and a few pics (like Turk does) is all that's needed.
I skipped and skipped through your videos, as things were repeated again and again, when a couple of pics would have done, with text to explain.

Sorry, but's that's just the way I feel about YouTube stuff.

No worries No_GazM - if you don't like YouTube why did even bother looking and commenting negatively when I'm just sharing how I did things? I do my videos in the way I find others helpful in explaining things. So it may not be to your tastes. Feel free to skip this thread anytime.

Here's how I went about making the center console for the AC unit - with a few added extras:

Part 2:

And then you really had to wind me up....HAHAHA
6x9 speakers are the Devils Spawn!
Their job is to move in and out making pressure without distortion.
Imaging if your pistons were that shape (and consider why they are not!).
It's obvious, that unless the cone is totally rigid (like the old KEF 139 units), the shorter sides will flex less than the longer ones.
"6x9" is a made up number anyway....measure the cone area.
A round 5 1/2" speaker has about the same actual area to move air, and 20% is NOT blocked by 2 "twitters" (now called X...LOL)

As it's down below knee level anyway, you'd have been better fitting a single 8" bass unit and a couple of upward pointing mid/tweeters. (Could still have been fed from the same amp with suitable crossovers)......OH....can we still say crossovers, or does it have to be Trans now? :ROFLMAO:

You've been on the forum a few year now.....you SHOULD be used to the way I type/say things.
I've been banned twice for upsetting people, but they still allow me back as I "amuse" or even sometimes help, the other 99%:oops:
I'd LIKE to read a write up on how you did things, especially in the "Technical Articles" section (That is made for these sort of projects), that can have pages of enjoyable reading.

To Quote you:
Feel free to skip....
That's what I do with most YouTube videos, as only 20% of it is informative. the rest is just someone wanting to hear their own voice.:eek:

Still "skipping" through your YouTubes.....hehe.

HATED the loud music on the wiring one!

One point on the drain tubing.....
AC is actually wonderfull to have in conjuction with heating in cold weather.
Heater up full, and you get condensation inside (if you get in the van with a load of snow on your shoes...like I'm doing this time of year).
But turn the AC on to remove the moisture and water will run out of the drain(s).
It's -11C as I type this.....
If you have such a small outlet, it's almost certain to freeze up!

I have 2 AC/heatpumps in the house.
They used to be supplied with 22mm hoses to drain the water.
Then they found that they froze in winter, so stopped supplying them.
Now I just have a path underneath the 2 that you can't walk on in winter as it's pure ice!

The wife got a Fiat 500e last March.
It's F***ing BRILLIANT in winter!
Turn the aircon/heating to Max, and it's all defrosted in 5 mins, and "toasty" inside (my T4 ticks over for half an hour to de-ice, and the temp gauge never moves!).
Looking where the engine should be, I can see the drain tube for the aircon is about 30mm outside diameter, and "flares" wider as it goes under the car.
