I have a 1998 Nissan Frontier XE King Cab, with 113,500 miles on it.   For
the last few months the odometer quits functioning at times.  It will work
normally, then it will disappear, or sometimes, when I start the truck it is
not on, then after driving 5-10 miles it magically appears.  It doesn't seem
to be getting any worse, but I would say it only operates about 30-40% of
the time.

Is this an expensive item to replace?  Would I be better off leaving this
repair (or replacement) to the dealer, rather than an independent repair
shop?

Thanks for any and all information.
