I'm pleased to say that finally I solved the problem. Thank you all of you for your help. The problem were the motors! because the Bosch ones use different electrical connection. I also had to change the regulators because they ere modified. Thank you to Scott from Corvette Kingdom for his help and for selling me good used motors and regulators.
Now I only need to regulate the windows because they are not going up 100% with the door closed
