When I switch on my defrosters I get a load moan from under the dashboard. It sounds like a pump straining. It starts quite builds then stops then starts again. It only happens when the defrosters are on. Does anyone have any idea?
i have found the problem it is in the in cabin filter i can't figure out how to get it out to clean it but i was able to blow most of it out. how do you get that flirer out on a 2001 frontier
