[Milan Markovic]

Hi!. I have vectra b 2001 z16xe engine. I have problem with turn light signal flasher. When i turn on electronic climate control blower motor fan if i tun on flasher for turn left or right blower motor fan sluctuate speed. Separately dey work perfect. Is it flasher relay problem? or something else? It feel like ground problem anywhere. Does anybody have any idea what to do? On opel scanner diagnostic no fault codes for eclectronic climate.
