All power windows out! Please help
 

So my rear wiper has been dead for a long time. Went to the junk yard to get another, plugged it in and still nothing.

Like a genius, I was trying to see if I was getting voltage to the rear motor with a multimeter and touched the probes together and created a spark. Now all four power windows won’t budge. Oddly, the wipers work fine and rear squirted fluid works too (except rear wiper.

I check the driver’s side fuse and it is ok. What happened? How are all my windows out? Is the relay baked? What can I do :( ?

check all your fuses 1 by 1.

ended up being the no. 12 fuse. It does rear wiper and all windows. Changed the fuse and at least I have windows back.

As for the wiper, the wire may break inside of the rubber bellow going from tailgate to the body

At the motor connector there will be three wires : light green/red tracer, blue (or green) and black
The blue (green) wire has 12 volts with ignition on
Black is ground
Light green/red is going to the rear wiper switch and connected to the ground when ON
Two ground wires are needed to allow motor to stop at home position (the arm continues to move when switch is off until the motor park switch opens.
In order to troubleshoot, get the test light (12 volt, 3.4 Watt bulb, NO LED!!)
Disconnect harness from the motor
Turn ignition ON
Turn the wiper switch ON
Connect test light to the harness between LGn/Red and Blue (green) wires
Light off:
run long jumper from test light to good ground on the body
probe LGn/Red wire again
Light OFF
check and repair LGn/R (power source) wire
Light is ON
Blue (green) wire is open OR there is a problem in the switch

Also:
When black wire is open but blue green wire and switch are OK , the motor will stop at random places when switch is turned off
When both black and blue (green) wires are open the motor will not run at all
