Expanding electrical problems on 1998 Ranger
Purchased a low mileage 1998 Ranger about 6 months ago in very good condition. As a new vehicle (to me), thought all of the electrical components were working fine. First indication of problems when I noticed that the dome light switch seemed defective and set it in the extreme left position which served my purpose. Couple weeks later, noticed light was no longer going on and, around the same time, noticed that the warning 'chime' only sounded 2-3 times when key left in ignition or faster sound when lights left on. Looked at some posts and took off door panels and confirmed switches on doors were functioning properly. Checked roll dimmer switch seemed fine, fuses checked out (and cleaned), no sign of corrosion.
Within few days, saw that the dome light was working again, chime working as designed....but only lasted a day or so......
Then driving, a 'flash' on the instrument cluster caught my eye and dome light and chime working again. I then realized that what had 'flashed' was the indicator lights of the 4wd high low settings on the instrument cluster. While dome light was working again, heard distinct 'click' under the dash when opened doors, check relays after dome light reverted to being inoperative. There are three, purchased a replacement and tried in each of the locations under the dash, no luck. I have now noticed that the 4WD actuator, that worked when truck purchased, no longer illuminates the dash signal light when engaged, presumably, also not engaging 4WD. Checked continuity of switch per another post, actuator checks out fine. Only power going into actuator was the when the instrument panel lights were on, presumably to light up the actuator? Just today, after poking around again, the dash lights are not working.......checked all the fuses again...all working.......
Other trouble shooting, check wires going from A-pillar to door as was advised as been know to break, took off dome to check it out, took off bed light to check (brake light there works fine). Unfortunately cannot find the Battery Saver Relay or the Interior Lamp Relay as advised (unless they are one of the three mentioned above).... Have gently tugged and pulled wires, wiggled the key, giggled gear selector........
Now, after a period of weeks where, for some part of the week, I'd see the dome light back working, I have been in darkness. Thus, I have been unable to determine if, when the dome circut comes back, whether the 4WD actuator functions as well?? Luckily, through all of this, the truck runs and drives great, so as of now.......any help or suggestions, would be greatly appreciated.... Tim
