Hello friends, I bought my 2004 model 307 xt premium brand car about 3 months ago, and I joined you but this sunroof problem has pulled me out for 3 months. At first, the sunroof of the vehicle was installed, and thanks to you, I was solving my problem with the reset method I learned, but the sunroof button doesn't work anymore. In the past, when the headlights were on, there was light coming from the points on the button, but there is no light anymore, there is no reaction at the button. I also tried the method of resetting the vehicle by inserting the polar heads of the battery and waiting for 3 minutes, but the sunroof no longer reacts. The only solution to this is my engine replacement? For the new engine, they put a figure like 1000 TL for me, but it costs me a lot. If you have friends who can help me, thank you very much in advance.
