No power windows, rear defroster, sunroof, or map lights

Recommended Posts

For a little while now, my passenger side window
has not been dropping down to allow the door to open/close. So I bought the
microswitch and went to install it on saturday. Well, it wasn't until after I
had the door panel off that I realized I don't have the triple square bit to
remove the latch assembly banghead.gif NO worries,
I'll put it back together and do the fix after I pick up the correct tool.

So after the door panel is back together, I fire it up and notice:
the power windows don't work
2- sunroof doesn't work
3- rear defroster
doesn't work
4- map lights don't work.

Now, what would pulling the
door panel off and putting it back on have ANYTHING to do with this list of
failures? I checked the associated fuses in block D of the fuse box. They were
all fine. Is there a relay connecting all of these features that may have

One other thing that I can't imagine would have an impact: When I
went to remove the door panel, the wires that go to the little orange LED in the
handle pulled out of the connector. I plan on picking up some wiring supplies at
radioshack to fix this, but its only the handle LED...if that is somehow wired
in series with the rest of those features...I would have to question Porsche's
sense in that.

Anyone know what might be going on here? Also, does
anyone have a wiring diagram of this car?

On all models, .the fuse are all side by side D1 power window D2 rear defogger D3 sun roof....Take a good look at the condition of the fuse box and also those three fuses. Also, if you got a voltmeter, look if you got power to the D1-2-3 row of the fuse box. The power for these three fuses come from the current distributor and If you don't have any power you have to go to the current distributor (under the dash passenger side) and look for a fuse of 80 amps. It is the third one from the left according to the wiring diagram. Look if you got continuity. If not just replace this 80 amps fuse.... First time that I see this kind of failure ??? Hope this help. Please keep us up to date with your findings....

Loren got a good point unless you know that you have created a short by mishandling a live wire....I was trying to found a part number for the fuse and only found a kit for over $28.00. Item 13...May be there is a number on the fuse and you can get it from the dealer....

Hey guys, im not having any luck finding the current dist. I had my head burried under the pass side dash and there arent any fuses visable. Took off a plastic cover to find the blower motor for the vents. Any input on this? How do I get the repair manual you refer to above?

Finly fixed it. I removed the current dist earlier and all fuses were fine. Checked them for continuity and they all passed. So not knowing what else to do, i began pulling every fuse in the drivers side compartment. C3, a 15 amp was blown. Huh...put a new one in and bingo problem solved. I'll check in a little while but I am not even sure what C3 is described to power. Thanks for the help guys.

Ouch...Lot of wok for a small fuse.In fact C3 is for alarm, power window, sun roof and top inside light....Sorry for the extra work.....But happy it is resolved....

Yea, I felt pretty dumb missing this! So D1-D3 are redundent fuses? I saw those fuse descriptions first, and stopped there.

Anyway, taking out the current distributer wasn't such a big deal. Learned a bit about the car. I'm just glad it all works correctly again.
