If I remember correctly this is usually caused by a break in the band. What do I need to repair it?
mine has the same issue. is it in the middle of the element?
On my 08 I have 1 band in the middle that does not seem to work either. I inspected it several times in the sun, with a bright light, etc., and could not find any break. Not even a wear mark.
Is there a trick to finding the break?
I think it may be how its made? vs. flawed part?
I use a VOM to check for breaks in defroster grids. Just hold one lead on the side of the grid and test (carefully) the suspect line at 1 inch intervals until the reading changes to locate the break.
