My vectra blowers will not work on any setting. I’ve taken the glove box apart and tested the current and the fan is getting power and also works when testing from another loom. I have replaced the resistor but still nothing. Also checked all the fuses. Would this mean there’s a problem with the switch? As in where you turn the blower on from? The button for the dentist also doesn’t turn the blowers on. At a loss and don’t want to keep replacing bits to find out it’s not that! Any help much appreciated
