I have a 2002 LE with the all-mode 4x4 system. I think that's the ATX14A transfer case. When I drive in the rain or it gets wet the 4x4 short out, which needless to say, is frustrating and kind of defeats the purpose.
Here are the symptoms:
1. 4x4 light is on.
2. ATP light ( that indicates that the transmission is not locked in park) will glow dimly in P, but transmission is parked. In 4x4 low and Park, it glows more brightly.
3. In Auto mode, there's a buzzing noise from under the vehicle.
4. Self diagnostic mode gives a 1 long and 4 short pattern indicating "2-4WD shift solenoid valve circuit is shorted or 2WD switch of 4WD shift switch is shorted."
5. It seems to dry out and fix itself relatively quickly (several hours).
There are two electrical connectors near the transfer case on the driver side that I was able to disconnect. I put some dielectric grease in them, but it did not solve the problem.
Does anyone know where this short might be occurring? Any other ways to diagnose?
Thanks.
