when i drive my car and it seems like when it gets up to 200 degrease the speedometer and turn signals shut off and wont come back on till the car sits for a couple hours . it has 185000 miles .. need to figure out how to fix it

Can you give anymore details or history of this problem? Going to be hard to diagnose based off your one sentence description. I've never heard of a problem like this.

after 30 min of driving both the speedometer and the turn signals shut off everything else is still on im not sure why it does it and it has been doing it since i bought it last year.

So just the speedometer? The RPM's still work?

When the turn signals don't work, do the hazard lights work?

the rpm and speedo turn off and yes the hazzard lights still work when the turn signals shut off

So its the speedo and RPM's... what about the oil pressure, temp, fuel and boost gauges?

those work to its just the 2 that dont

I am having the same issue with my 2000 SSEi, tach, speedo, odometer and turn signals not working. I've had the dash apart checking all connections, checked all the grounds. I'm stumped.

I found the problem with mine. After scouring the web, this site and others. I found a similar thread that stated their problem was caused by a faulty relay not sending power to the Ignition 1 fuse. I checked mine and the fuse was missing!!

I was checking fuses the other day and put it in the wrong spot!!

I replaced the fuse and all works again.
