no heat from demister on vw polo.........help me!!
Discussion
Hi guys/gals
I was wondering if maybe somebody could help me sort out this problem, seems even when temp guage is well up to norm and even though blower is running fine and it seems the cold to hot selector dial is actually working, sounds like the flap is moving or whatever is in there is changing anyway as switching back from hot to cold brings fresh air into car, switching back to hot setting with blower running at any speed produces very little if not any heated air either when set to direct up to window or to footwells or generally through air vents, I've removed carefully the flow and return water hoses ( don't know which is which, but suspect right one as looking in from front is supply ) correct me if I'm wrong, there's hot (really hot!!) water flowing out of one on right, and builds up at left if hose slightly opened as if to bleed, I suspect this is return but isn't returning ( think this the problem!!???, is there a device , thermostat which enables return flow maybe??.....I'm lost from here, any help greatly appreciated, oh ya it's a 1.0 ltr 1999 vw polo, engine running fine, and hot enough, thanks in advance for any assistance and for reading this.
