Heated windshields

[Krill]

when only 1/2 of the windshield heats its a blown fuse, there are 2 fuses for the front windshield. one operated the left side and one for the right. in the center of the glass(inline with the rear view mirror) you can actually see a 1/4 inch space where the left side heating element ends and the right starts. but yes if only one side is heating 9 times out of 10 its one of the 2 fuses(located in the engine compartment)

my parents alway laughed when I would talk about land rovers, saying how unnecessary 1/2 the features are( heated windshield, steering wheel, windshield washer jets) about 3 weeks ago I met my family in New Hampshire..... 12 degree weather and snow. mind you they were in a base model kia minivan it was priceless to watch them drive with gloves on and stop on the side of the road to pour a bottle water on the windshield in hopes of washing it off.... then waiting 10 minutes to now melt the sheet of ice from the water they had just poured.....I pulled up next to then and laughed( as I used my windshield washer)

Great story. ONLY in a LR do you have a 2 fused windscreen

I drove 100 miles last weekend to help a friend move. It was -21F on my ride up. I drove that without a coat thanks to the heated seats, steering wheel, windshield, etc. I don't think I'll ever own another vehicle without at least those features in this region. Granted I did find out that "Auto" climate control needs to be set at either 84 or Max to keep the interior warm when driving 80mph at -21F.

Reading through the forums.. still no solution to why mine doesn't work at all. Both 40amp fuses are fine, connectors are fine. I read somewhere the brown and green wire coming out of the battery may have something to do with it.. can someone ID what that wire is for? Mine is coming out of the positive terminal. Should it be on the negative?

Do you have a heated windshield installed? If so then remove the A pillar interior trim garnishes and confirm the ribbon power straps are plugged into the windshield.

The windshield is original and in good condition. I removed both A pillar trims and it appears the straps are all plugged in.

OK good. Can you snap a photo of where the two fuses are? I assume the heated windshield light comes on when you press the button?

Or. While the covers are off hit the button and check the current with a multimeter. Will the windshield not activate if it is too warm?

Pretty sure temperature doesn't matter. I've kicked mine on in the Arizona heat before, and the interior lights still dim. I'm sure the duty cycle is much shorter though.

Most multimeters only support up to 10A and the windshield pulls a full 30A so will just pop the fuse in the multimeter. Instead I would check voltage between the two leads in the A pillars. At the same time disconnect one of the leads and measure the resistance between the two windshield leads: It should be ~0.3 Ohm.

If there is no voltage to the windshield (A pillars) the next thing that I would check for is voltage to the fuses: pull the fuse, one side should be at ~12VDC (batter voltage). As I recall the switch is after the fuse, so fuses should be "always hot" but confirming would take someone who already knows, or time to stare at schematics when I have a few minutes.
