I was defogging the bach hatch window with the electrical heater, and noticed that there are only about two and half of the elements that are applying heat.
A couple thin strips cleared, but not the whole hatch window.
This may be a more general repair topic, but is there a home remedy way to fix the connectivity of the elements if they have breaks in them? Conductive paint, tape, epoxy, or something?
Or should I just order a new Mazda part for $X*10^6?

They have repair kits for your exact problem.

http://www.frostfighter.com/ is an example of something that claims to work.


go into an advance auto or somewhere similiar and ask for a defogger repair kit

I know people who have used the repair kits and they seem to work. Unfortunately if your windows are tinted you are SOL.

how exactly would you check for where the break is using a test light or multimeter?

Hmmm. curious why tinted windows would be any different for repairing heater grids...?

DamonB

Because the tint is on top of the grid. The repair kit is essentially a paint that you use to repair the break in the grid. You can't paint it on if you have window tint.

I knew there was a reason I didn't like my tinted window. Could there be a way to mask and locally remove the tint on a long enough strip to paint on the conductive paint? Is there a good chemical to remove tint?
