2010 370z roadester climate control problem
 

guys i need help its been more then a year with this problem , thanks god i have 2015 370z nismo as a daily driver

my climate control switchs dosent work at all but my ac works with full blast either cold air or hot air somtimes it comes from the front facing vents somtimes from the legs side , when i try to press any button related to the climate control it doesnt respond , keep in mind that my car comes with navi and everything related to nav audio car information works just fine .

so i tried the following :

1 changing the climate control
2 changing the ac amp
3 changing the headunit with the screen and control
4 tested all the fuses inside cabin and outside next to the battery
5 tested the head unit by going to the hidden menu and run a full dignosis
6 checked all the connectors and cleaned them

all that work and nothing helped me to fix my problem keep in mind that all the parts are tested and proven to work
i dunno what else i should try , i live in dubai and summer here is hell the temp reaches up to 50 c , so their is no way i can drive my car with this heat without a reliable ac .

so please please any ideas will be appricitaedhttps://uploads.tapatalk-cdn.com/202...f888577d99.jpghttps://uploads.tapatalk-cdn.com/202...a68dae6942.jpghttps://uploads.tapatalk-cdn.com/202...585e05d832.jpghttps://uploads.tapatalk-cdn.com/202...3d6059f575.jpghttps://uploads.tapatalk-cdn.com/202...184e4c4f4f.jpghttps://uploads.tapatalk-cdn.com/202...4739598c63.jpghttps://uploads.tapatalk-cdn.com/202...3af2dbd3c6.jpghttps://uploads.tapatalk-cdn.com/202...d0580a86ed.jpg

Sounds like a resistor.

It sounds like a good candidate but from i understood from Google their is no blower motor resistor in 370z unless it comes built in the actual blower motor coz I've tried googleing the location of it , the only result that came back is the blower motor itself or the ac relay. Any idea where it exists?

No, I'm sorry I don't. Electrical system issues are frustrating and are definitely not my thing. What about the HVAC relay? Have you checked that?

I'm surprised no one else has chimed in to this discussion yet.

Check the R134 pressure on the low side. Too much R134 will cause it to blow cold for a bit, then switch to hot as the engine heats up.

There is a sensor that might be causing your problem. It might have gotten unhooked.
