Help, my 89 1500 speedometer has been acting up for about a year now. Have had instrument panel out several times and upon reassy it SEEMS to work for a while then back to reading zero or on and off or not at all. I replaced the transmission sender and that was no help. I have inspected the printed circuit board with a magnifier twice. Cleaned the 4 pin connector twice. Only thing I haven't cleaned is the multi pin master connector and plug between dash and instrument panel. Could it be the computer? New parts like the speedo module and circuit board are unavailable. Any help is welcome.
