Help Solve Electrical Gremlin in '98 T4R
My '98 T4R 3.4V6, Auto 4WD developed an electrical problem, requiring that I remove the Tail Relay in order to drive it (during daylight hours only!).
With the Tail Relay in, weird intermittent things happen, not only do the parking lights stay on when turned off, but sometimes the starter motor stays running after the engine has started and when engine is turned off, the starter keeps cranking the engine until the battery is disconnected. Also, with the Tail Relay in, one time the engine started and the starter motor kept running until I turned the light switch on, and the starter motor immediately cut out, and when I turned the lights back off, the engine shut off immediately, even thought the ignition switch remained on. I substituted another Toyota relay into the Tail Relay circuit, same things happen. Has this happened to anyone here? It still runs great except for the electrical problem, without the Tail Relay plugged in, it runs normally, head lights, brake lights and turn signals work, but plug that Tail Relay back in and it does some strange things! I've taken it from 75k to over 250k and this is the first problem I've had with it. Does this sound like a grounding problem or maybe a bad light switch or ignition switch? Any comments are appreciated!
