OK first off I have repaired rear defrosters in the past and I cant find an explination on anything here or anywhere for my issue and heres what Ive found First off only had my 2011 Journey RT AWD for about 8 months and I live in the very cold part of Canada in the winter. So i never had time to figure this out. I hit the rear defroster switch light comes on .. stays on for about 5-10 min then turns off as it should bit wont defog the rear window. Pulled the panel off no voltage at the contact... hit the switch now I have 12volts... then check the other side also with 12 volts... hit the switch goes back to 0 volts. Across the entire grid 12 volts from left to right no change 12 volts across but comfirming with a thermal temp gun temp never changed on the grid or anywhere the rear defroster is on the window stays a constant temp. So I confirmed switch works as it should and voltage across the back window from left to right.. with a test light and multi meter... even used the multi meter from side to side of one of the lines it produces 1 ohm of resistance which I figure is too low. My wife has a 2012 caravan basically same car and parts... and her defroster works.. it has increased resistance but at 6 volts so why would I have 12 volts across and no heat generated. Does the journey have a relay somewhere for this.. I cant hear a click anywhere when i turn the switch on. Please help as winter is comming and any help is appreciated
