Nissan Repair: Auto Climate Control, nissan murano, climate control

Question
Dear Von,
Refer to my Nissan Murano MY05. I got the auto climate control services recently. Airflow was hindered and the same was serviced.However, after service i noticed that when Auto CC is enabled it opts a default mode and if the temp is >18 (if we change manually also) hot air used to come thru the vents. I woudl request you to please guide me with ur valuable suggestions  abt the issue. Regards,Raj,UAE

Answer
Raj,

I would think the control panel is defective.  It is electronic and that is what controls the blend doors and causing the hot air coming out the vents.  Now, if it worked before the service I would have them show you the system pressures on the air conditioning system.  40 to 45 on the low side and two and a half times ambient on the high side.  That would be something like 275 degrees in the UAE.  I am dealing in Fahrenheit not Celsius.
