Drivers side power windows not working

Hi,

Do the left windows go up or down? In other words, do they work at all? If both are not working, I suspect one of two things. There is a chance that the 25 amp circuit breaker is bad or you lost ground.

1. confirm there is constant power to the dark green wire at the main switch on the driver's side. If there is, move to number 2.

2. The rear window/driver's door switch... Check to see if there is power out from purple wire with the switch in the down position. Also, check for power out from the same switch in the dark green wire with the switch in the up position.

3. If there is, move to the rear door window motor. Check the same color wires for power to them at that point.

Let me know what you find at that point.

___________________

The driver's side window receives power direct from the power supply (dark green we checked in the first step).

1. At the motor, check the dark blue wire for power with the switch in the up position.

2. At the motor, check the brown wire for power with the switch in the down position.

Let me know what you find.

Since both left windows are not working, I suspect the first step, where I said check for power from the circuit breaker, is going to indicate there is no power.

Regardless, let me know what you find.

Hi,

Yes, you can use any known good ground. As far as the CB, it shouldn't be getting hot. That is indicating something is drawing a lot of power. As long as it isn't kicking off and it is the correct amperage, you should be okay.

Let me know if there is power at the switch.

Take care,

Hi,

It sounds like the circuit breaker is bad. If you run power direct, there is no protection from overload, which could lead to a fire.

Since there is no power out from the circuit breaker, replace it first. I highlighted the CB in the pic below. It's in the instrument panel fuse/relay box.

Try this and let me know.

Hi,

I attached a pic below showing pillar locations. As far as the G308, yes, it will be behind the trim in the pillar. When I get these, I remove the trim from the area identified to locate the exact location.

C200 is behind the upper left kick panel. The kick panel is located where your left foot would lean against if you were in the driver's seat. However, if you look at pic 2, it indicates G200 on the right side. Interesting, the manual contradicts itself.

Hi:
If it has power and doesn't work, it sounds like a motor issue. If there is power to the switch not making it to the motor, it sounds like another switch.

Confirm power to the switch and then to the motor and let me know what you find.

Take care,
Joe

Hi,

I attached the schematic below for you so that you can reference what I mention.

Do you have power in from the circuit breaker (dark green wire)? If you do, if you try to put the window down, do you have power at the brown wire going to the motor? Note when checking for power, make sure to use a known good ground. Don't depend on the opposite wire at the motor for ground.

Let me know.
