i posted a thread not long back about how my heaters randomly stop blowing on/off when they are turned on. ive noticed when they come n go my windowns will stop working aswell.

i noticed by the lights on the window buttons flicker on/off when the heater goes on an off.

can anyone help me with this?

help?

First thing to check is that the smallest wire connected to the starter motor is sound and connected properly.
