Lekker Ian!

I spent a lot of time replacing all the blown incandescent bulbs in my Patrol with LEDs, but I believe it's worth the hassle. The great thing about LEDs is that they will probably outlast me, and may even outlast my Patrol...

So - I've been waiting for Mr. JP (happy birthday, btw) to come and collect his climate control unit. In the meantime, I've been rolling with the refurb unit in my truck. It's been quite a while now. No issues at all.

One of the possible issues I thought about with the new 3D-printed light bases was potential heat. ie: Theoretically, LED's do not generate much heat, but I had no idea how much heat would be generated. I was concerned that any heat - especially from the resistor as this sits in the base - may cause deformation. I'm happy to say I've had two LED's in newly 3D printed bases running for more than 24 hours whilst mounted as they would be in the vehicle (ie: in an enclosed space - one inserted vertically from the lid, and one inserted horizontally from the side). No deformation. And no issues to report at all.

I've got to get new resistors, and after this I'll be reconning my climate control unit with the new 3D-printed bases.

I've not had a lot of time for a while, and over the holidays I switched off entirely. No laptop, no cellphone. Nada.

I've got another two climate control units I need to restore and got around to this by printing the parts last weekend. I've just finished soldering up the lights and resistors today, so I've got 4x T4 backlights (for the buttons) and 4x T4-Tall backlights (for the screen).

I'll get around to giving the first unit a good scrub, grease the buttons etc. And reassemble it again over the weekend. This is the first time I'm using my own design / 3D-printed parts. So we'll see how it goes. :)

Ian,

thanks a lot for this great guide! you really did a marvelous job and I am sure some of us due to your work will be able to also redo their climate control units.
Actually you just inspired me to also replace the front bulbs. In addition I took the luxury to get two new buttons for the recirculation - I'll try to post an update when I was successful, the parts now need to find their way from Partsouq to me in Germany.
