2001 Instrument cluster failure when hot out

I know I've seen this before on the boards but can't find it. On my 2001 xterra the instrument cluster goes crazy when its hot out. The odometer disappears and the gages go to zero or read high. Then the truck starts to buck and won't go over 52mph. once it gets cool enough inside, everything returns to normal. I've previously read that this is caused by a faulty circut card in the instrument cluster. Does anybody have the partnumber of the faulty board and can I replace this myself ?
Thanks

heard this before. has something to do with some sensor that goes to the transfer case. I'd dig up the old thread but.............. Steel X whatcha got?

Huh ? you mean which Xterra ? 2001 SE v6 Auto.

The same exact thing is happening to me now! No mechanic has been able to find the problem, did you ever figure out the party and/how to replace it??

Don't know if it will help, but I recall this being discussed a long time ago. As Craic mentioned, it had something to do with a sensor and forced the computer to go into "safe" mode. the speed limit is what brought it back for me.

But this is all from memory. Results will vary...
