The drivers seat electric controls on my 944 stopped working. I checked the passenger side seat and it was dead too. This led me to the fuse box as I thought a blown fuse may be the culprit. I had forgotten how many fuses there were. They were all numbered and I was wondering if there is somewhere I can find a guide that will match each fuse with the electronic device they protect, because I obviously had to go through them one by one until I found the burnt out one and replaced it. Any help is greatly appreciated.

I just ordered the six volume shop manual for the 944. I paid 299, which is close to how much I paid for my four volume Jeep manuals. I know all the same info is available for free on line but I think I'm just too old school to do it that way

Hi, the inside of the fuse box cover should have all of the respective fuse and circuits.

Here's a picture of the fuse box label:

Hi Paul -

I know this is an old thread, I thought maybe someone might throw out a diagnostic protocol for fuse #11. I did a google search on "porsche 944 fuse #11" and ended up here so if I revive this thread and end up with an answer it could help others.

I bought a 944S2 out of Sarasota FL a few years ago and my friend drove it back to California for me but the lighter didn't work so he couldn't get his iPod running, which was an intolerable condition for him. Being practical he just installed a "leech" connector from the battery to a pigtail cigarette lighter in the cabin and drove it cross country.

Now I have it and and found out there's a short on fuse #11. I even burned a 30 amp fuse on it. Dead short. The problem is that fuse is connected to darn near everything. Where should I start figuring out the short? I couldn't find a flow chart for it in the manual so I figured I'd just ask the community for hints and best practices?

Thanks,

Try disconnecting the cigar lighter. They can and do short out because of the way people jam the plugs in.

If that's not it, try disconnecting each item that is on that circuit.

Since you are probably thinking you will need a few thousand 30A fuses, check around either at some better auto parts stores or on Amazon for a 30A circuit breaker that plugs into the ATC fuse socket.


PS I have seen the overhead dome light break internally and short out.

Great Idea Paul, thanks,
