Heated Rear Window
Posted: Sun Aug 21, 2005 9:45 am
How can I check if my hrw is working without it being iced or fogged up. My car has an alternator and voltmeter, so no obvious discharge as seen with an ammeter. I suspect it's not working as the headlights and heater fan do not dim/slow down when the engine is at tickover and I switch the hrw on. Is it possible to measure the resistance across the element maybe? Also is there another fuse box to check other than the 4 in the dash, my car is a UK spec 1973 S130/5.
