Speedometerand temp gauge quit

CHeck the earth returns on the instrument cluster. The behavior points to a loose electrical connection rather than a short or fuse.

Check wirring for damage

No it's not it works on the can. Controller area network.
suspect battery fault or more likely the instrument cluster is at fault.
do all gauges drop and the speedo reading is just dashes?
if so this is a cluster fault. Sorry!

You should have a fuse in the fusebox for the instrument cluster. The instrument cluster houses your gauges, speedometer, clock, and temperature gauge or light. Check the fuse to see if it blown and replace with the same size number on the fuse. Don't decrease or increase the number of the fuse. Stay with the same amp number that is on the old fuse when you replace it. Hope this helps.Good luck.

Most common, internal problem within instrument cluster. R/R cluster and sublet to speedo shop for repair.

Sounds like you need a new car.
With joking aside, the problem with your speedo, tach, gas guage, temp gauge and odometer can probably be one of two things. Check your fuses. If they are fine you may need to replace your cluster panel. I had to have the entire thing changed over my speedo not working right. It was not cheap. You might want to check the relay box under the hood. Does your transmission leak? Check the fuses and relay on it also. Get a new ignition switch and replace the old one if your key is stuck. You can try WD40 on that key but don't expect any miracles. The bearings are likely shot. Sorry I posted all of this bad news. Good luck.

If its still clocking up the miles then the speedo its self is faulty,Fit new ometer.Not senser.Good luck

Switch ig. on, ground the sender unit wire for about 3 seconds see if the temp. gauge moves, if so change sender unit, if not then it is a faulty gauge reader.also check instrument voltage stabilizer.

4 resistors on the back of cluster bad get them at radio shack.

You will also need to swap the speedo cluster. thats where the anti theft module is located. After that you may still need to relearn the key switch.I will look at the wiring diagrams and get back to you on the starter circut in side the vehicle. You may have to change some other things.Talk to ya soon. Dan
