Is there a relay/breaker responsible for power windows, front and back wipers and sunroof?

Check the relays. There just under the driving wheel inside a closed box. Just take off the box and you should see about 7 relays. The big one in the far right corner controls the delay mechanism for your windows #4. What I discovered is theys relays can get really hot and just stop working. No wonder why my windows stopped working when the inside of the car got hot.

If there really hot, then try replacing them and see if that helps.
But first make sure you find the relay that controls the power windows.

These relays are designed for delay response, like our head lights or your power windows so they can still function after you've taken your key out of the ignition.

Sorry Bill but you don't the tool's or knowledge to take on this job . Control module's involved.
Which one does your vehicle have ?

THERE ARE 2 FUSE BLOCKS UNDER BACK SEAT. One holds the Delay Accesory Relay, and the other the Power window and sunroof Breaker. If no power to one side of breaker (with ign on) check Relay. If there is power then you must check PW switch in Drivers door.

Under the drivers seat, in the b piller area on the floor. Check the RED wire at the power window switch and if it does not have power, then check the breaker and relay (relay is beside the breaker). If the sun roof works, the breaker and sunroof/window relay is good.

There are 2 fuse blocks. The Power Distribution Center is under the hood along the passenger side fender and has fuses and relays in it. The other is on the passenger side of the dash and has fuses and circuit breakers.

Power is supplied to the Power windows and sunroof through the power window circuit breaker. That circuit breaker is supplied power through the RAP (retained accessory power) Relay, the RAP relay also supplies power to the radio. The RAP relay is also fuse protected by the RAP fuse in the under hood fuse block. The RAP relay is energized by the BCM body control module.

The RAP relay is responsible for the radio and windows working after the igntion is turned off.

The first place to check would be the RAP fuse in the under hood fuse block and then the RAP relay in the Body fuse block.

A list of the BODY relay block located on the left side of the dash to the right of the interior fuse block is below:

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

hey did you ever figure this out? Im working on the same problem right now... have power to the sunroof and just replaced the 25amp circuit breaker that is right after the sunroof... I have a circuit diagram if it would help you at all

check the fuses and Circuit breakers for the Window system. could be as easy a popped fuse or stuck breaker.

hope this helps. if u have any other questions just let me know
