I just finished installing my pioneer mp3/cd player, hooked everything back up and the CD player works but now when I start my car I have no control of the A/C fan speed and the digital gauge doesn't display anything but mph --- also my abs light and brake light are on and my fuel gauge reads "E" I went back this morning to double check that things were plugged in properly, like the plug that connects to the digital gauge and the one that connects that allows you control of the A/C but other than that it was pretty straight forward.

I disconnected the negative batt terminal for about 15 - 30 seconds to see if that would help but it didn't. Any ideas or am I going to have to bring it into Nissan?

Thanks

 

Check your radio fuse under the hood. On my G35 the same thing happened. The fuse blew when i jump started my car and the A/C was stuck on a weird position...
