how to fix 79 300 SD rear windows defrost lines
anybody has any idea how to fix the rear window's defrost line of my 79 300SD? it's been raining crazy here in CA and without the defrost line working, my rear window is fogged up all the time.
thanks for any good advice. |

If it is the resistive lines (on the window) themselves that are cracked, find the cracks (either visually or with an ohm meter). You can either buy a pen at any local parts store (e.g., Pep guys, Autohome

Good idea but, the lines on my W126 at least are inside the glass. If the W116 is the same way I would sudjest finding a used window.

My '79 300SD has wires IN the glass, not a grid ON the glass...........there is a relay that controls power to that.....is it working at all. I have same problem but not have managed to figure it out yet.
Keep in mind the 79 300SD is a W116 chassis
