Check all of these fuses.

Customer: replied 10 months ago.
An the relays?
Customer: replied 10 months ago.
Relays for Windows and ac compressor please.
Expert:  Dan replied 10 months ago.

There are not any relays, these are built into the modules and are not replaceable.

Customer: replied 10 months ago.
the ac compressors relay is built in, meaning I need a whole new compressor?
Customer: replied 10 months ago.
there are no relays for the windows, just fuses?
Expert:  Dan replied 10 months ago.

No the relay is built into the module that controls the compressor, the relays for the windows are in the door modules.

Customer: replied 10 months ago.
Where is the module for the actual compressor?
Customer: replied 10 months ago.
There is no 45 or 48
Customer: replied 10 months ago.
Changed all fuses and no response from windows. The only window that works is the front passenger
Customer: replied 10 months ago.
Please respond
Expert:  Dan replied 10 months ago.

Do the windows work with their individual switches in the doors? Does the drivers window auto up and down work?

Customer: replied 10 months ago.
No
Customer: replied 10 months ago.
I already bought and changed the master switch
Customer: replied 10 months ago.
The only switch that works is the passenger. There is no power to the master switch
Expert:  Dan replied 10 months ago.

Have you tried relearn procedure for the auto feature, this can cause the windows not to work.

Customer: replied 10 months ago.
The little green light on the master switch isn't lit up. Does relearning activate this securing switch, and what is the procedure if it does? Help.
Expert:  Dan replied 10 months ago.

Initialization is performed on the power window switch of the relevant door.
Requirements for correct initialization:
• Initialization with engine running
• Convertible top, doors and windows closed

Initialization comprises:
• Erasure of initialization
• Reinitialization

An initialization must be performed:
• In the event of malfunctions, e.g. no one-touch control function, no opening or if available no comfort function is possible
• After the power window drive has been replaced
• After work is carried out on the power window mechanism
• After a power supply interruption, e.g. disconnection of the battery or disconnection of the power supply to the door
• After the door window glass has been removed and installed or replaced
• After adjustment work on the door window glass
• After adjustment work on the convertible top
• After replacement of seals

Erasure of initialization:
• Open door window glass fully
• Operate power window switch in "Open" position four times within 10 seconds

This erases initialization of the power window, anti-trapping protection and toll function are inactive.
Check whether one-touch control (toll) function is inactive, otherwise repeat procedure.

Reinitialization:
Avoid a break between the two steps!
• Open door window glass fully
• Operate and hold power window switch in "Close" position (second switch stage)
• Once the upper end position has been reached, hold power window switch in "Close" position for approx. 2 seconds longer
• Open door window glass fully
• Operate and hold power window switch in "Close" position (second switch stage)
• Once the upper end position has been reached, hold power window switch in "Close" position for approx. 2 seconds longer

There was no work done or anything. As I was driving I rolled all my windows down, and none of them came back up except the passenger window.
Customer: replied 10 months ago.
Do I do this procedure with the good window?
Expert:  Dan replied 10 months ago.

yes try the one that works first.

Customer: replied 10 months ago.
Ok
Expert:  Dan replied 10 months ago.

Let me know if that works.

Customer: replied 10 months ago.
I will apply it soon as I get home around 8:30
Customer: replied 10 months ago.
Thank you
Expert:  Dan replied 10 months ago.

ok. Don't forget to RATE at the top of the screen, it would be greatly appreciated. Rating does not close out your question, we can continue replying here until we get your question answered. Thanks.

Customer: replied 10 months ago.
It worked on the window with power, but no luck with the other 3.
Customer: replied 10 months ago.
There is no power going to the switch
Expert:  Dan replied 10 months ago.

Maybe this will help

Customer: replied 10 months ago.
What is the footwell?
Customer: replied 10 months ago.
Module
Customer: replied 10 months ago.
Should I also add that either of the power mirrors work.
Expert:  Dan replied 10 months ago.

You may have broken wires in the drivers door jam, there is a rubber boot that has wires in it, this flexes when the door is open and closed, wires commonly break in this spot.

Customer: replied 10 months ago.
Everything else in the car works except my mirrors and three windows.????? I checked the wires in the door. There ok
Customer: replied 10 months ago.
Wherever the power from the master switch comes from, that's the problem
Expert:  Dan replied 10 months ago.

Check for power with a meter at the fuses that are in the diagram.

Expert:  Dan replied 10 months ago.

Check for power at the footwell module. Check inputs and outputs of that module. A scan tool would help as well, the footwell module could have codes, that would narrow down the problem.

Customer: replied 10 months ago.
Question, what controls the power tof the driver and passenger mirrors?
Expert:  Dan replied 10 months ago.

Does it have the cameras in the mirrors?

Expert:  Dan replied 10 months ago.

fuse F19 and F16 under right side of dash. no cams.

Expert:  Dan replied 10 months ago.
