the entire unit is divided into three parts as it is replaced by parts and not the entire unit.
get it check which part is defaulted
compressor:- it is the most expensive part to replace that could vary from 2000 dhs to 2500 dhs.
electrical Part :- it will cost you from 100 dhs to 500 dhs
AND
Air Conditioner Gas :- Again not very expensive from 100 Dhs to 150 Dhs
my CX9 2006 a/c compressor is constantly working, as it is a Japanese model car so i was not expecting it to have AC issues at this stage but it did the worst is that there is no cold air flow and the heater is working fine.
