Sup Guys long time since i posted a thread, i just had put nav tv to go in my car and a fm wireless and a half din dvd player, in my 05 coupe, everything works fine. SORTA! the sound is great the pic is fine, but i have NO a/c now. just blows hot air, has anyone had this problem? what is goin on?

 

Usually its just the harness connector not fully pluged in.

 

if the harness is not fully in, then why would the heat and blower work?

It may be a couple of pins not making it...

There may be another issue,
but this is a common one after DDin conversion & new HU

 

I'm pretty sure there are threads over in the Audio section that say you need to plug the temperature sensor in. The sensor is above the driver's right knee.
