2006 jetta tdi fuse box and wiring diagram, my rear window defrost isn't working

I still get the power lite on the dash when I press the rear defrost sw. I don't know if this switched "on" lite in the sw is separately powered off the fuse box or elsewhere? The rear defrost still isn't working so I don't know if it's the main fuse in the fuse box or not!

There are a couple quick checks you can do. I would remove the cables that connect to the heater grid in the rear window. First start by checking for continuity across the grid. Essentially turn your multi-meter onto the continuity setting and touch each connection location on the grid itself. Then test for power and ground.

I will be honest with you though. In most cases the issue is in the heater grid. A lot of the time the only way to fix it is to replace the rear window.

I'm and ASE Master tech, but I also worked for safelite for 4 years.

Btw the connections will be under the plastic C pillar covers.

Let me know if you still need the diagram after reading this and attempting this simple test.

Just my two cents.

SOURCE: Windows won't work

Your power feed to the window switch panel is a big wire loom that goes through the driver door. Check the connection at the door jamb. I've seen the plug slowly come apart just from the door opening and closing. You should have a power window fuse at the fuse block under the dash as well. The power to all the windows goes to the main switch at the driver door first then goes to the rest of the windows. Hope this helps.

2006 chevy impala rear window heater does not work

check the fuses the fuse for this can be found in your owners manual. if the fuse is good and the lite for the rear defrost lites up the rear heater strips on your rear window may be bad the only repair for that would be having the rear window replaced

2006 rear defogger is not working

I'm fortunate to work at an auto body shop. There is a technician here that loves these problems. We also have a wealth of source material at our disposal, which supplied no clues as to the problem. So needless to say this one stumped even him. While I was researching this rear window defroster issue on the internet I came upon a page that had the end fix for my car. Under the passenger side dash - mounted near the front passenger door jamb there is a fuse box with a wiring harness. Open the wiring harness to observe if there is a burn mark from a poorly connected wire (see pictures) if this is the case... (this repair is not recommended but it works) clip and seperate the offending wires from the harness and wire them together. then clean the wire harness from left over wires to prevent further short circuuits when the harness is reconnected. test the rear window defroster if it works you're good to go. Please consider placing in line a fuse. I don't believe you need one but the tech here put one in just in case. He used a 30 amp Sorry no photos-files are too big but trust me if there is an issue at this spot you'll know it. it is very obvious

None of the power windows work on my 1999 jetta

look under the dash below the instrament cluster.where the relays are there is a small metal box about 1 inch wide with a green label.that is the fuse for your windows.replace with dealer part only.
if that does not solve your problem check the ground wire from the drivers door to the kick panel ,
