Most engine surges can be traced to the IAC, MAF, TPS, and even the PCV. All except the PCV are operated electrically. Since the problem only happens when a dashboard or cabin switch is activated I suspect a chafed wire or short sending an electrical signal to one of the sensors listed above. I would begin at the the fuse box and look for chafed or burned wires.. Did you see if the engine is throwing any codes. That could narrow the search.
