as title states, tried searching but to no avail, rear defroster doesn't work, checked the fuse, its good, light still comes on but doesn't activate, would putting different rear speakers in the back have anything to do with it? thats the only thing i remember doing lately and the defroster used to work fine when i got the car. thanks in advance

There are little plugs that also go into the window area. Re check and see if you pulled one of the clips while you were installing the speakers. -
With the defroster on, see if you have power to the connector for the grids. If so, check continuity for each "line" to see if there is a break. There is a repair kit, if there is.

Here's an easy way to do this.Originally posted by miamibob View Post
JUST TOUCH THE LEADS TO THE GRID!!!! BE CAREFUL, YOU CAN SCRATCH OFF THE COATING AND RUIN THE GRID!!!!!!
Get a voltmeter, with the defroster 'on'. On one side of the grid there will be 12 volts, or battery voltage, on the other side of the grid, there will be 0 or close to it. If the grid is working, the voltage should read in the middle, about half of the total voltage you saw on one side. If you have battery voltage or 0 in the middle, you have a break in that grid. But make sure you have voltage on one end, and not on the other. If you have voltage coming to the grid, but you have 12 volts on both sides, you've lost your ground. If you don't have voltage, then your feed is bad. Most likely your switch.Comment
