Rear Defroster not working. Fuse is good but it just doesn't work. Any thoughts why it wouldn't work?

 

Check the wiring connector at the back to see if you get power, other wise sometimes the metallic strips will actually wear out over time. There is some conducting fluid you can use to repair them if this is the case.

 

Is there maybe a defroster relay?

 

everytime i turn mine on, it blows a fuse.

 

I will double check the fuse but I dont think its blown.

 

when I bought my crx the def did not work either.

I followed the test procedure for the circuit and it turned out to be a bad controller (the button on the dash).

10bucks and I had a new one off ebay.

 

Did it still turn on like it was working. Cause the yellow light will come on when i push the button.

 

mine just stopped working too.. fuse isnt blown. its weird.. guess i'll check out the button and see if its gone. i hate having to open my window a bit expesially since its getting cold out.

 

Mabe it was unpluged by the prev owner.
I unpluged the two connectors at the glass on mine due to not wanting to chance ruining my tint. Just a thought .

I cant remember for sure
sorry

I cant find a troubleshooting procedure on line.

so here are the steps from my manual

1.
check for voltage between drvr side window terminal(should be the pos term) and gnd(body)

if no voltage - faulty relay(in dash fusebox)
-open wire

2.
If there is voltage check for continuity from neg term(pass side) to body

If no continuity bad gnd wire


3.
If there is voltage at the pos term then you should read 6v from middle of each defgr window trace to neg term


To eliminate switch as issue.

open instrmt panel and unplug defog switch

turn ignt ON
check for voltage between blak/yellow and blak wire
-if no voltage , broken blak/yellow wire

If there is voltage

connect a jumper from blak/yellow to blak/green terminals and turn on ignt
deffoger should work with jumper
If it does the you have a bad switch

relay test:

Bottom of relay.

a-b should have continuity when bat is connected to c-d
a-b should be open when no bat

Hope this helps

why would it ruin your tint? iv tinted my own back window on a cougar and it didnt ruin it. everyone thinks its bad for tint when its not.. tint is made to withstand the heat from the sun and that gets alot hotter then a rear defroster.

 

Check the connections to the glass...might be corroded.

 

how do you fix that problem?^^^

remove the connectors(carefully)
and put them back on.
repeat a few times
