I am having an issue with controls.....I have a 2008 J480 with the Poly Planar Stereo...... I have the stereo head unit out for repair right now.
It seem that all of a sudden the Pump 1 and Pump 2 control button do the same thing...that is the turn on and off both pumps. Everything is working fine just when you push pump 1 or 2 both pumps come on and when you push 1 or 2 both go off...
It did start doing this after I pulled the stereo could that have something to do with it??
Thanks Frank
