The above is a link to a speedo repair gear site.

Sunroofs have to slide in a channel and if anything gets stuck in there, even felt, it can cease to function.

Is your sunroof powered or manual?

If it is powered, I would look for a fuse first. Then, if the fuse is alright and a test light says that you are getting power at the motor, then it's a bad motor or it's getting 'stuck' in the channel.

Look above and below it as the button operates the powered sunroof, if so equipped in your 928s4 Porsche.

Nice car.

Good luck on repairing these problems.

Speedometer is not working


For the speedo, you could have a bad connection, or sender unit, but it could be the gauge too.
For the sunroof, you could have a bad switch
This two things happened at the same time?

1999 528i transmission bad or sensors bad


the speed is getting signal from the abs unit, but that not only were the signal goes, it can go to the sunroof air bags auto box and so on. if the signal is being distorted, the speedo will drop or stop. inturn same for the auto box. i would start with the sunroof unit as its a common problem with the sunroof units to go faulty. it may still work but when you open the sunroof it sends a signal to the speedo and the engine that its open and adjust the mix and speed. also the same if you have A/C there is a signal that needs to be sent to adjust engine control. it takes a lot of figuring out when this problem arises as there are a lot of possibilities. I think its a blue wire but its been a few years so don't count me to that, code for the wire will be in a haynes manual ti goes from abs to speedo and has braces off to everything it goes to.

I have 1993 jeep grand cherokee spedometor stopped working and rpms are high and fuel consumption is poor


Time for a tune-up! Need to have it diagnosed thoroughly. Likely your speedometer not working is not related, though. I know on the older models the speedo was operated by a cable from transmission up to behind the dash panel. They can break inside the sheath that covers the cable. Pretty simple fix-but you may need to pull out your instrument panel slightly to reach behind and unclip the end of the cable from the speedo. First, unhook end from transmission, grab end of cable and twirl it: someone inside the car can see if the speedo needle moves slightly when you twirl it. If it DOES move your speedo in the dash may need replacing. If it doesn't move, your cable is likely broke. Just get another from a salvage yard.

1989 Honda Accord speedometer not working. What is a speedo head?


The speedo head or cluster is the part that houses the speedometer and tach, etc. now it may be the speedo cable that comes from the transmission to the speedo head that has broken. If so replace the cable and your back in business. If it is the head you can get them from your local recycle yard.
