hard opening windows

friends, I have 307 models of 2003 model, when I press the glass automat, the windows open with difficulty, I wonder if there is something like this that makes the opening of the glasses slippery and closes.

My teacher, why is it the bastard, or you have to look at it because of its engines

you change your worst engine. I don't think you're a mess

Those glass motors are very strong. Not the cunt turns it into a cardboard box. It is probably a situation related to the engine or electricity.

the same problem exists in my mind I think the problem may be on the rails of the mosque if the glass is slightly shaking back ... It is very weak when downloading 2 mosques at the same time.

Absolutely either from the engine or the electrical installation.

Just like the glass on the right is pretty good, the window on the left is closing hard, I think the problem is on the window's sight, the engine is on the top, because the engine is yuke. ; right & nbsp; Also, when you press 2 glasses, it drops so much more.

thanks, then the first job is to have the vehicle's electrical installation and window engines checked & nbsp;
