View Full Version : Let's do Climate Control Shuffle!

I was at the wreckers today, getting a shifter assembly for my "arm" project, and found another upgrade.

I now have all the bits I need to fit the TL/TW centre console (climate control) to my TJ Sports.

At least I HOPE I have all the parts. One thing I don't have is a clue as to how to do the conversion TJ to TL.

It gets better! My son has a series one TJ and I'd like to fit my TJ climate control to his car. So again, I just need clues as to how to get that to work - TJ Climate Control to TJ No-Climate Control.

Any pointers, tips, tricks or moral support would be appreciated.

Replace all the harnesses, except the floor, engine, roof, doors and boot.

So that leaves main instrument, upper dash, and the two that snake around the outside of the engine bay and include the main fuse box.

You'll also need the external temp sensor, the motors for the air box and vents, as well as the resistor for the fan which is different.

Yeah should have searched before posting. I found the information to do mine - TL to TJIi. Then found the TJII to TJ... and took a step back.

I have to take another trip out to the wreckers to pick up the interior temp sensor and the vent hose to it.

I wouldn't bother converting a TJ to TL climate control. It actually is differently wired electrically, and though it plugs and plays nearly, it won't work properly.

And you lose the outside temp as well as the display.

Ooooh, Jesus. What do you mean "won't work properly"? It won't control the temperature correctly, or, the controls won't work? I feel like I've been black flagged on the last lap.

My main incentive to do the conversion is that I prefer the TL centre console look and layout. I'm not going to miss the display, as fancy as it is.

More searching will help, but it is mainly the control logic that's the issue. All the motors etc work, its just the fan speeds, the missing engine bay relay, and the blower control that's the issue.

I don't have the luxury of search while I'm at work. Had a poke around using my phone, but sheesh.

So my radiator fans will only run on low or high speed? Or will my blower fan only run at low or high speed?

The search results I kept coming up with reference the climate control conversion being done on TH/TE to TL. My car already has climate control, including the exterior temp sensor and light sensor... Not sure if it has this additional relay, but what critical component am I missing going from TJII climate control to TL/TW climate control?

Have a look at that.

It is to do with the eco function. Turns out the system wont run the compressor as often or as it should due to the different ECU expecting there to be less wires/different wires and an extra fan relay

If I read that right, it's the Auto function that goes to poop doing this function? The blower fan still responds to the fab control in the TL console. Essentially making it a prettied up version of the TJI Air-Con.

I could probably live without the Auto function.... probably.... maybe. Might sleep on it.

I did see a list of everything needed to swap it out properly. It was a substantial list. No shortcuts?

I just re-read your comment.

The AC compressor isn't ON as often and as a result the blower fan functions more often/at a higher speed to compensate?

But this state only occurs when the "Auto" mode is selected... pretty sure that's how I understand it.

I can't confirm this as I have not done this conversion. I currently have a TL and KL and much prefer the earlier climate. So when I had the KH I never changed it.

But it is relatively easy to splice in the plug and give it a go. You can always change back.

I'm stuck!

How do I un-pin the wires from the black plug?

Driving me bonkers so my guess the solution is simple.

Anyway, I couldn't un-pin the yellow wire so I cut and soldered the sensors yellow to the plug.

The purple wire I'm more than sure I put in the wrong slot. I found a female pin to fit, soldered it to the end of the purple wire and inserted it into the small black plug three in from the RH side (looking at the female end of the plug).... pretty sure that's not right.

First test reveals the AC blowing hot air and not allowing the airflow through the front vents.

Previous to my hack job the AC was blowing cool air and allowing me to direct the airflow.

Really just want to un-pin the wires right now.

generally you can't. You have to cut them out. Or force them.

Oh man, do I have some questions for you!

First up, where did you source the "new" pin to connect the purple wire? I thought I had this locked when I pulled a replacement pin from an old stereo harness. But I don't think it was making a connection despite fitting into, and locking, the black plastic plug.

The image that floats around here I am sure identified the wires as though you are looking at the black plastic plugs from behind, can you confirm this?

Do I splice into the existing yellow wire, or, do I cut the yellow wire and run my sensors yellow wire only to the black plastic plug?

Yesterday I walked away from the project, not wanting to damage anything, leaving the TL climate control in place, un-modified wiring. And I'm sure it appeared to be "working".

This despite after I initially assembled it, the AC would only run cool air if I set the temp to 20 degrees. Anything higher, like 25, would produce heated air. The ambient temp was higher than 25.

The two pins changed are for the internal cabin temp sensor. Without this it will blow hot air.

That's how I understood it.

Things are weird with the TL climate control installed on the stock TJ wiring.

First install, Sunday, I had only cold air if i set the temp up less than 22 degrees, hot air otherwise. Makes sense, I expected that. I also had control over the direction of the air - feet, windscreen and so on.

Monday rolls around and I wire in the TL cabin temp sensor. Which I'm pretty sure I failed at because all I got was hot air and no control over the air flow.

So I put it back together - reconnecting the original yellow wire. And now all I can get is cold air unless I spin it around to over 25 degrees.... almost 30. It was cold this morning so I was expecting some warm air at 25 degrees. I again had control over the air flow.

The only thing I did differently was to leave the purple wire in the small AC plug. But, I'm damn sure the pin isn't connecting quite right with the brain of the AC controller.

I'm going to make a tool similar to what Wombat suggests, then loot a bunch of the correct pins. Try again tomorrow.
