I have a 95 Chevy G30 van. The power windows, power locks, and power mirrors stopped working when I installed an electronic trailer brake controller. I disconnected the controller. The circuit breakers are fine. Where do I look next?

Check the fuses in the panel under the hood. You have most likely blown one of the fuses in there. If all the fuses are ok then a common power wire to those areas has become open.
