Hi guys ive had a few posts on here but ive managed to find out what the problem is. A few months ago i did a double din conversion and bought the newer double din climate control unit. I did the conversion and everything has been running fine. Last week i left my sterio on and the battery wet flat so i had to bump stat the car down a hill which was fine. It was then i noticed that the drivers side door had stopped working, the windows wouldnt work, the buttons werent lighting up and the car wouldnt alarm. I kept my older climate control unit so i thought i wold try pluging it in to see if it makes a difference and it does!! when you plug the double din one out everything works as normal and when you put my old one in everything works as normal, but as soon as you put the double din one in the drivers door stops working!!!! What is going on? ive heard you sometimes have to get theses things coded but i dont understand why when it was working perfectly before my battery died!. Any idea how i can sort thisproblem? Can i not reset the climate control some how? Any help would be much appreciated!.
