2003 Infiniti G35 Q&A
2003 Infiniti G35 Question: radio and a/c controls not working
Start by checking all of your fuses. Then if they are ok, you will need a good automotive electrical diagnostic person to dig deeper. http://repairpal.com/directory?address=08831&car_brand_names=Infiniti - dandd
For some reason, the controls for the AC and the radio run off the radio power supply. You're going to have to replace it. Cost me about $300. - Visitor
This just happened to me. It's apparently a common problem with the factory stereo on '03-'06/07 G35 models. Like Answer #1 says you can see if it's a fuse problem. Also, a small section of VIN numbers do have a recall on the factory stereo in case this problem occurs so you can check to see if your car was covered and you can get it fixed for free. For me, none of those options worked and the infiniti dealer in South Jersey quoted me at $550 for the repair. It's normally more, but he said something about "since it was a common problem, Infiniti gives that flat rate now." I went a different route and installed a double din aftermarket radio/dvd player for close to the same price. - Visitor
My G35 AC auto turn on and I couldn't turn it off. All the control light went off. The AC goes to MAX. Any idea?
