Thanks. Buzz has a two month waiting list and you only get on it by sending in your guages. I don't know if I can handle two months without guages.

Sorry to hear that, I did mine during the rainy season when I wasn't driving much. His lead time might have been a little shorter at that time.

Apparently, some cars that he did the guages on won awards at Pebble Beach, and he's been inundated with business. Good that good people are getting recognized. That's the way it's supposed to work. I think the uptick in his business may last until if/when he staffs up. Rainy season is wrenching season, after all.

I know he restored a Tucker gauge cluster for a car that Rob Ida was working on.

Thanks rkwfxd! How difficult is it to take the clock out ? Any tips or tutorial available? I’ve never done it and I fear Ivan break something else... during the time the clock was it for repair did you happen to drive your car or it is not possible? Sorry for the dumb question! Thanks!

Grab the clock and pull. Should come right out. At most you might need a putty knife or credit card to slide under the rubber ring to get it started. It is not bolted in at all, just pulls out. Once out, there are two plugs in the back. IIRC remove the small one first then the large one. Done. I had all the warning lights replaced with new factory warning bulbs. I did not go to LED or anything fancy. I think there are like 13 of them or so. Install is just the reverse. Simple.

I did my fuel gauge at the same time. I did not drive the car. I believe I probably could have but like I said, mine was only down for four days.

I fixed this by following David Ream's procedure for Fixing Airbag Warning Light and seatbelt Warning Light Gremlin originally published on porsche964.co.uk/technical/clock.htm (This site is no longer active)

It is quite easy and requires resoldering some solder joints on the clock circuit board.
I would be happy to mail the procedure to anybody that is interested. It is 5 pages - any better way to post the info?

Thanks you everyone for all your tips and advice! Really really helpful!!

I am not sure I can do that, it looks like simple but I don’t have that skill set to be accomplished as a DIY unfortunately for me.

One question - what about take out the two lights / bulbs (Airbag and seat belt)? Has someone done this and what the consequence would be, if any?

Also from where do you start counting bulbs to know exactly that you are taking out these two?

just as a short term plan before addressing it completely in a few months. Any thoughts?

Yeah I saw that thread about fixing it myself. I did a lot of RC racing years ago and have a ton of soldering equipment and experience but decided to let a professional do it.

Yep you can probably pull the clock and remove those bulbs and forget about it. I believe that will also disable the airbags as well - not sure on that but it seems EVERYTHING runs through the clock on these cars.

You can also buy a airbag disable plug thing from Pelican Parts for about $30. It plugs in under a panel on the passenger side of the tunnel.

You could just live with the glowing lights.

You could put a small piece of black electrical tape over them so they are not as noticeable.

OR, you could pull the clock, send it in and have it properly fixed for the next 20-30 years of service for $250-$300. Pretty much the cheapest and easiest fix of ANYTHING on these cars.

Lots of talk about the clock. Have your codes turned off first and see if they come back. It still could have been a momentary voltage fluctuation that caused the code.

Hi there! Quick update from my end on where I stand with this issue. I went to my local shop and got all codes cleared. I was the happiest person on earth ...but my happiness latest only 15min and a couple of revs up to 5000 rpm....after one strong acceleration lights popped up again ...!!!!

I am am planning to get them reset again and clean seatbelt and below the seat with electrical contact cleaner spray and see what happens...any idea why the issue popped up again under heavy acceleration? What’s the cause - effect and the rationale behind...? Your are thoughts are as always more than welcome!!! Thanks in advance
