I dont know if anybody out there might have this same problem that i do if you do please give me some info. today in the morning i turned on my 2004 g35 and saw that the AT check light and Air tire sensor where on which i thought ill make an appointment to get it serviced. But as soon as i was driving i noticed that the speedometer was not working although the gas and temp where working and to make things worse as i was getting ready to change lanes the frequent turn signals did not work!! I totally **** my pants!!! So when i decided to go back home to change my pants! jk. I decided to take a look around the motor to see if everything look alright, which determined everything look right. So later during the day i ask one of my friends to have a look at it and when i turned the car on everything was back to normal, no lights where on speedometer was working including the signal lights where once again working?????? I dont know if anybody out there might have this same problem that i do if you do please give me some input on the situation i have, this problem happened today so ill need to check back to see if it does again tommorrow.
