Question about Cars & Trucks
The speedo and temp are from two different areas. Two different sensors,So it's not the gauge fuse. The lights could be a fuse. But all three could be from a bad connection at the instrument panel(IP). I would check the fuse for lights first. After that I would scan the PCM. If ll that checks out, I would looking at the plug really hard.

Probably a fuse out. Usually under the dash by the driver's left side.
Hope this helps.

have you got a dimmer switch on your model to dim the dash lights. if you have it may be faulty. link the cables together if the lights work the switch is faulty. if you have not got a dimmer switch
your printed circuit on the back of the dash may be faulty or the plug in the back of the dash is not pushed all the way in. hope this helps

Common problem on BMW's apparently...there are on-line repair services but they are NOT cheap...100-300 bucks. Tough to fix yourself...unles you are a highly skilled techie!

I have this problem too and my new Saab mechanic told me that I would probably need a new instrument cluster. He said a brand new one costs $2500 but that he would order me a used one from a car that had fewer miles than mine as you can set them back but not forward. He both diagnosed and temporarily "fixed" the problem by slamming his hand really hard on the dash over the panel and all the lights and gauges immediately started working fine....for now. I haven't had the work done yet (I have a 1998 Saab 900S with 130K) so if anyone has any other ideas about this I would love to know what they are. This issue with the gauges and dash lights has been happening on and off for over a YEAR and this is the first time someone has had any idea what it is. I already had my ignition switched replaced so we know that's not what it was. THANKS

There has been issues with the solder joints on the PIN connection to the gauge cluster. The issue being that over time thru vibration and such one of these solder joints will fail (happened on or 1999) you can repair this though. You will have to remove all of the trim from around the driver's side dash board, this will include the trim towards the center of the dash. Once these pieces are remove you'll need to remove the gauge panel (I believe (4) allen head screws) carefully bring the panel and release the wire clip from it. Looking at the back of the panel, where the plug was, carefully with plenty of light look for one of the pins to have a failed solder joint. It will be very faint however the failed joint will be a fine dark line around the pin. To correct use a small soldering iron and reheat this solder until it wants to flow, let it cool and reassemble.
As I fore mentioned I had the exact same issue as you are describing, our is a 99. The most tricky part is the dash, take your time with it.
I hope this may have assited you,
