How To Guide: Remove and retro fit Air Conditioning.

Post by BX Bandit »

As I am about to do this, I thought I'd try to document what I'm doing.

This will take some time to complete as I will retro fit at a later date, but removal has, in part, already started.

I know there are a few who have done the same and/or similar, so any pointers, contributions and help gladly received.

I'll invite the first bit of help: does any one know if the wiring loom for air con is an added plug in loom, or is it grafted into the original loom in a non plug and play way?

The loom is all bundled up together but you should be able to separate the a/c wiring from the loom with average difficulty in the same way that ABS wiring can separated out.There is not much of it really especially if you already have the twin radiator fans and relays installed.

Thank you Vince, to be honest I think I need my head reading. I wasn't in methodical mode yesterday so I stopped.
I also want to add the TZD spec wiring loom - so many darn cables!

So Jaba, it's just a case of locating the relevant loom(s) and unbundling/disconnecting them, no snipping required?

The twin rad cooling fans are already in, but there are extra controls/cabling for these aren't there? Fr when the a/c is on?
Also I need to remove the wiring for the
Recirc fans
Pressure switch
Compressor
Cabin side controls.

There are also two extra relays under the little black box shelter that sits in the near side bulk head. Are these a/c related?

Afraid so mate, there will be snipping where the a/c connects up with the existing cooling + blowing circuits, unless you want the extra pain of removing and installing those as well.
There are 3 relays for the twin rads somewhere under the bonnet usually then a further two for the a/c. They are all usually beside the LH blower.

Interestingly my TZD with no aircon seems to have the underbonnet connectors for the a/c bits neatly protected by plastic bags.
