Climatronic [emoji736]
thanks to wonderful pdf how-to from Szymon, i manage to do the upgrade successfully and at the same time make good all the additional wiring i made so far through the right channels.
From manual A/C, all wires reuse except the manual got extra one wire from SB25. Pin14 from the manual panel.
Then, my dome light lost its door-switch ground connection (T73a/4). The wire was cut! inside the big wiring loom which from outside looks fine! Maybe while taking out the steel beam behind the dash, it may been twisted and break.
Later, i got error from the air flow flap motor. Lucky the lower flap was just out of its rail. thanks to iichel for quick guide!!!
And i’m impressed with the climatronic performance and control algorithms. perfect!!
