NISSAN Pictures of how I fixed the rear window defroster on my 87-95 Nissan Pathfinder.

The defrost lines in my rear window have gaps in them, which stops current flow, so the lines do not heat, so my window stays foggy. Sick of it, easy fix. Here I go.

But first, lets pay some bills:

  1. I got this little kit from Permatex. Usually like the Permatex stuff. It has some alcohol to clean the window and a tiny bottle of conducting fluid and a tiny brush to apply it and a tiny line template to paint through.

  2. I shone a light through the window so I could find the gaps in the rear hatch defroster lines.

  3. I marked the little tiny gaps with tape.

  4. I found the gaps visually, then used an ohm meter to test that these are indeed gaps.

  5. OF = open fault. no conductance, gap in heating element.

  6. I cleaned the window where there is a gap in the defroster element.

  7. I used tape as a template because I thought I could make a thinner prettier line.

  8. I painted the conducting fluid over my template.

  9. After drying for some amount of time as specified on the instructions, I removed the tape, and ... walah! A nice new line that conducts and heats and defrosts properly so I can see the jerk tailgating me in the rain.

  10. Next I sold out to make 02ยข so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.

    But no minivans!

  11. Then I finished my beer.
