I have a 2005 g35 coupe that i just installed the metra double din kit on and now my heater/a/c is stuck on 75 degrees... I looked at the back of the control board and according to metra there should be a jumper on option 1... in all the other forum posts i have read it says to remove the jumper all together.. Everything else works on the controls except for the tempature up and down. It is stuck on 75 degrees. I have checked the sensor under the steering wheel and that is connected...any help would be amazing...thanks

Did you try it with the jumper removed?

Yes, ive tried it with the jumper removed, ive tried it every witch way but cant figure it out...please help
