2000 Jimmy Wipers do not work front and rear

I have a 2000 GMC Jimmy and the wipers do not work. I confirmed that the motor and switch is good. The reason they dont work is that 12V is not present at the rear and front fuses. I power probe the fuse and the wipers work. I read in the manual that there is a circuit breaker to protect the motor if the motor is working to hard in the snow/rain and the breaker will trip rather than blowing the fuse. My question is where is the circuit breaker, nothing is listed under the hood stating Wiper circuit breaker. I believe this is why 12 volts is not present at the fuse panel, I believe its open and did not reset......can someone help me please. thanks, Art

The front wipers get power from fuse #17, (25 amp) in the instrument panel fuse box, (left end of dash). The circuit breaker that you mentioned is a thermal limiter inside the wiper motor and is serviced by replacing the entire wiper motor. With the ignition in the RUN or ACCY position, both terminals of the fuse should show battery voltage.

The rear wiper gets power from fuse #23, 15 amp fuse in the instrument panel fuse box, (left end of dash). This motor also has a thermal limiter inside the wiper motor and is not serviced either. With the ignition in the RUN or ACCY position, both terminals of the fuse should show battery voltage. There is also a 15 amp fuse in the underhood fuse panel labeled "RR WW". Both terminals of the fuse should show battery voltage at all times. There is also a cut out switch and a logic module for the rear wiper only.

Concentrate on the front one first, post your results.

The circuit breaker was just right of the drivers side A/C vent behind the dash, there is another Relay/Circuit breaker block there. The front circuit breaker is a 30amp painted green. Thanks,

Not sure what you found as far as a circuit breaker, it's not related to the wipers unless someone added it after the vehicle was built. The factory wiring schematic shows a yellow wire from the fuse: it splits and then one wire goes to the wiper switch and the other goes to the wiper motor. What color are the wires on the circuit breaker that you found?

In the manual it states the wipers have a circuit breaker, the dealer confirmed and I found the OEM relay/circuit distribution box behind the dash just right of the drivers side vent. Its bascially right behind the inside vehicle fuse panel, very hard to get too plus you need a mirror to see the relays and circuit breakers....peace out.

Either the dealer is wrong, (wouldn't be the first time) or the GM factory shop manual is wrong. ;)
The front wiper circuit for 2000 S&T series uses a 25amp fuse.
Which means that when amperage draw reaches 25 amps, the fuse will blow and shut off current flow in the circuit.
It would be pointless to use a breaker in a fused circuit: The fuse will not allow amperage draw to exceed 25 amps.
The breaker will not pop until it reaches 30 amps, (Ain't gonna happen) ;)
Here's the schematic, follow the yellow wire from the fuse directly to the wiper pulse module, (no circuit breakers).
