My1998 dodge neon speedometer works every now and then why?

I had this problem and nobody could figure out the why. After searching on the internet, I found the problem was coused by soldering issues on the circuit board for the gauges. My husband was able to resolder according to the instructions on a web page found at Neon.org. Search for speedometer and use 1st gen for the forum to search. This will bring results regarding fuses and resoldering. Unfortunately, the resoldering that was done only lasted about a year.
