Hi, how are you? I have a little problem that drives me crazy with a Renault glass lifter. It turns out that the motor plug reaches 12.7 v when the key is pressed, but once the motor is connected. (That test with the battery that works correctly) Stop getting tension so it does not turn on, the same happens if I place any load, either a lamp. What can be? I think it has no relay for that mechanism. It is an R11
