Al,

I'd check circuit breaker 79 which should be in the front panel by the driver's side door. I'd also check the normally open water shutoff solenoid on the ceiling of the spare tire compartment. Your maintenance manual at section 10.1.2, page 22-42 says to:

1. Faulty control circuit: Check the electric system by energizing the solenoid. A metallic clicking noise indicates that the solenoid is operating. Absence of clicking indicates a loss of power or a defective solenoid. Check for open breaker, open-circuited or grounded coil, broken lead wires.

2. Burned-out coil: Check for open-circuited coil. Replace coil if necessary.

3. Low voltage: Check voltage across the coil leads. Voltage must be at least 21 volts.

4. Excessive leakage: Disassemble valve and clean all parts. For best results, replace worn or damaged parts with a complete spare parts kit.
