I have a FixOrRepairDaily '97 4X4 Ranger with two seemingly electrical problems. The first has to do with the speedo and odometer. At least 1x a week, the speedo and odometer wont register when I'm driving. The speedo needle just sits on 0mph and the mechanical odometer doesnt turn over. There is no speedo cable. It is electronic going back to the transaxle where I think I see possibly a sensor mounted. When I start it the next a.m., speedo and odometer will work.
The 2nd prob. is, every so often+ usually when its pouring
rain, the inside dome light + glove comp. light wont turn on. This wouldnt be a problem if it werent for the fact that the "bright" engineers at Ford also put the electronic 4X4 circiut on the same circuit as the dome, glove box circuit which I have ascertained so I also cant put the truck in 4 wheel drive when this problem happens. I checked all fuses both inside and in the engine compartment(even swapping them out to see if outage happens elsewhere) but to no avail. I have no idea where this circuit is grounded, so I dont know if ground may be going bad. I am suspecting that a relay in the dash is going bad but my employers auto tech. thinks it may be my ignition switch going bad even though I dont see it in the schematic wiring diagram for this truck. Finally, I did bring this truck in to a garage for the 2nd problem but they couldn't find whats wrong.
