Left Front Power Window Switch
The battery voltage is applied from the WINDOWS circuit breaker through CKT 42 (RED) to the accessory time delay relay. The accessory time delay relay supplies voltage through CKT 70 (PNK) to the left front power window switch under the following conditions:
?€¢
The ignition is in the RUN position.

?€¢
The retained accessory power (RAP) is active.

When an UP switch on the left front power window switch is operated, the battery voltage is applied to the power window motor. The power window motor is grounded through the DOWN contacts of the left front power window switch to G204. The motor runs in order to drive the power window up. When a DOWN switch in the left front power window switch is operated, the battery voltage is applied to the power window motor in the opposite direction. The power window motor is grounded through the UP contacts in the left front power window switch to G204. The motor runs in order to drive the power window down.

see the diagrams attached and chart, and fix it. God bless you

It may have slid off the track from the water. If it doesn't start working once it dries out, a day or two depending on the weather, take the door panel off to make sure it is on the track properly and that the cables/wires have not corroded.

Either the master switch or a partial open in the wires in the hinge area.

Check for a broken wire in the door jam. Other wise I think, You need to research this more, that the Left Front Power Window Switch is actually a door module. I would guess it has either lost power or gone bad.

since it works from the left button its not the motor, so it would have to be the switch that,s bad. replace right side switch and you should be back to proper operation.

check master switch,window motor-regulator

Might have to open and see if the powerr comes to the unit. If not there can be a break inthe door hinges section where the main power comes in.
If power is present but not the control, it can be failure of the switch control, failure of the logic control IC, failure of the motor.

the contact is bad you can check this by switching the wires and you can get the front window down, this will verify the switch is bad and need to be replaced for the front window and all the others to operate properly
