I'm having some bad issues with the power windows on my e36 coupe. They ar not working at every time. Tested the power supply, fuses, comfort relay, switches, power motors and ignition key switch and ground. Some times the comfort relay flicker and they work after that. But even when i pry the contacts manually on the relay, they still doesn't work. But when i open the door, both sides go down (does't know the name of this feature). And i can tell if the car have the zke module. Only have one in the passenger side. But it is for locking system. It worked perfectly since 2016.
