Hello,


So my ac doesn't work anymore. My heater works but only on the bottom and top and rear vents. The center vents do not work at all. Before I start splurging on more items I would like to gain some insight. Please, HELP. Its so hot in the bay area and would like to get this fix asap. So far ive replaced the blower motor and the resistor. I'm receiving the climate control unit today so hopefully that might be the problem since its such a easy fix. Or could it be heater valve control? I've spent in total of 600 dollars already getting it diagnosed and on parts mentioned above. Its sucking me dry again please help


Here are the codes its throwing off:


009C5C IKHA: Evaporator temperature sensor

009C60 IKHA: Heat exchanger for heating system, sensor, right

009C67 IKHA: Heat exchanger for heating system, sensor left


00E706 IKHA: Heater-AC systems LIN bus fault




0099C55 IKHA: Fogging Sensor






S0072 No communication with control centre/control panel

 

Hi did you find out anything here? I have this exact issue and would really appreciate a response!!

 

I've read a fault fog sensor can cause these issues, somebody with NCSExpert can disable it, but that wont solve the codes for all the other issues your having.

 

Thanks for your response! Interesting, do you know where you've read this?

so I figured out what my problem was. It was actually just the climate control unit. so I'm assuming the butt connector or the buttons were faulty but I replaced that and t works now! bought one off eBay for like 80$. good luck on your ac man!
