[colamangr]

Hello guys!

I have a serious problem running... I got from a friend the automatic a/c the IHKA i think. I have the simple a/c IHKR. What are the parts that i need to have so i can retrofit it in my car? I think i am missing some...

Thank you all!

IMHO the ihka is not an upgrade.........I havethe IHKA in my car andcit is difficult to demist the windsceen,you must usually engage the air cond or push the demist button which turns the fan on full and diverts all air to the windscreen vents which is so noisy it will drown out the radio on normal volume or drown out a normal conversation.Its not really an automatic air cond system either.My 2c
