I am having problems with the gauge cluster. sometimes the speed , sometimes the temp and other times the fuel. How can I fix this ? Anthing helps

I have the same problem in my 2000. The shop NEVER finds anything wrong. This is what i do. Unhook the positive battery cable for 10 minutes, then pull out the computer chip and replace it. Hook up the battery cable and everything should work again. The shop said nothing was wrong and so this is the only way i have found to fix it.

I found out the problems with the gauges . Replaced the vehicle speed sensor , and the coolant temperature sensor, and that fixed the temp and speed problems , and the gas gauge hasn't gone bad since, for some odd reason

I'm not saying your sensors weren't bad, but did you happen to unhook your battery when you replaced them? I'm no expert but have come to learn through this site and doing some extra reading elsewhere that the communication systems in these newer vehicles are highly susceptible to poor grounds. The positive battery cable did reset the modules, but typically it's a poor ground that caused the problem. Take your ground off your battery also and clean it and tighten back down. Make it a part of yearly maintenance. If you do have problems after this , locate the ground of the component(s) you're having problems with and clean them also. Do this before you shell out big bucks on parts swapping. Too many times you swap a part out and in doing so you inadvertantly clean the ground for that part and it appears the part was bad. If you only cleaned the ground first, I'm willing to bet it would fix the problem 75% of the time if not more.
In fact the auto manufacturers are now engineering specific grounding posts into the future vehicles to help eliminate grounding issues. Not just putting a screw into the frame to make a ground. Rust and corrosion are not your friends.
