rear window defroster problems 850 1993

Hi..

I noticed the other day that my rear defroster has stopped working. The side mirrors still defrost and the fuses are all intact. This car has the defroster with the many little, barely noticeable wires inside the glass, that, when on slightly bulr the glass.

I am wondering if this is a simple case of a ground that has come loose or a loose wire otherwise to the window itself. Before I go tearing things apart I am looking to see if anyone has come across this problem and if so, where I might start looking. The manual I have lists nothing about the rear defroster...leaving me somewhat clueless as to where to look.

Any help will be greatly appreciated as the cold weather is here and ice on the windows in the AM has once again begun :(

TIA,

Nate Brown

Nate,

How long do you leave it on? It takes a few minutes to begin to defog or defrost the glass.

Also, have you cleaned the window with anything sharp that may have broken one of the "wires" They are relatively fragile and if there is a break in continuity, the grid won't heat.

You could use a voltmeter to check if power is flowing to the grid, and then check each grid line until you find a break. If not there, there may be a break in either the power or ground wires to the window.

Bryan
