Not a fuse problem .
Voltage is applied to the left front window switch through the PWR WINDOWS PWR SUNROOF circuit breaker and to circuit 143
Retained Accessory Power (RAP) Circuit Description
The Body Control Module (BCM) controls the Retained Accessory Power (RAP) feature. The RAP feature allows for the operation of the following components for 10 minutes (or until a vehicle door opens) after the ignition switch turns from the RUN or ACC to the LOCK position:
• The radio
• The power windows
• The power sunroof (if equipped)
The BCM interfaces with the vehicle's power distribution through the RAP relay. The RAP relay allows the BCM to control the application of power to circuit 75. Circuit 75 provides power to the following circuits:
• Circuit 43 -- Radio
• Circuit 143 -- Power windows, and the power sunroof, if equipped
When the ignition switch is in either of the following positions, the BCM energizes the RAP relay by grounding circuit 707:
• ACC
• RUN
The BCM turns OFF the RAP relay when the ignition switch is in the START position. This action disables the RAP feature during the engine crank and bulb test.
When the ignition switch turns from the RUN or ACC position to the LOCK position with all of the vehicle doors closed, the BCM leaves the RAP relay energized for 10 minutes, or until any vehicle door opens. (The BCM detects a ground signal in circuit 49 or circuit 727).
The BCM resets the RAP timer when the ignition switch turns from the LOCK or OFF position to the ACC or RUN position.


I would check the RAP relay . Accessory Time Delay (RAP) Relay
Behind the IP compartment, attached to the underside of cross-car beam.

SOURCE: Radio and Sunroof both stopped working at same time. Fuses in 3 locations all seem to be good.

Not positive it is the same thing, however, when setting up my iPOD adapter to the radio, I made the mistake of not following the instructions to the T, and it caused my sunroof to stop working... after a day (which I later found out gave the system enough time to "reset" and connect), I turned on my stereo, pushed the 3CH to Dolby Surround, and that did the trick. It's been about a year... and I've had no problems with the sunroof!

SOURCE: lexus gs300 dash lights ,sunroof,gear lever,windows, not working

hello freddy - the good news is that your lexus has a self diagnosis system built into it. this is what you need to do.

drive to an auto zone or similar autoparts store and have them put your lexus on their computer to scan for trouble codes. they offer this as a free service. with a little luck this scan will isolate the problem and the fix will be quick and easy.

if this doesnt fix it for you get back and let me know what codes popped up.

here is a link to the lexus trouble codes so you will have added insight. good luck.

SOURCE: how to change the rear 3 spark plugs on a Buick regal LS 2002

You can try rotating the spark plug boot a little bit-not even a 1/4 turn-to break the seal between the plugand the boot. Then pull the boot wire off with a pliers on the metal boot shield. Once the boot has beet rotated on the plug, the shield helps to remove it.

In a 1999 buick regal ls, do I have to remove the headliner to replace the sunroof switch?

No you don't need to remove the head liner to replace the switch . Here are the factory service repair manual directions .
Grasp the switch on the left and right sides. Use a small flat-bladed tool in order to disengage the clips which are located at the front and rear of the switch. Hold the flat-bladed tool parallel to the roof and push straight in. Rotate the switch toward the left side to disengage it from the mounting bracket and pull down. Disconnect the electrical connector from the switch. Remove the switch from the vehicle. This switch is supplied 5 volts from the sunroof module on the brown an orange wires ,the dark blue wire is grounded inside the sunroof module . The switch is just a low voltage input to the sunroof control module , The control module opens or closes the sunroof by the inputs from the switch . The odds the switch being bad are astronomical , more then likely the motor or the sunroof module are bad.
Your best bet would be to have a qualified repair shop diagnose the problem for you ! Do your power windows work ? Sun roof is powered by a circuit breaker an the windows are powered by the same circuit breaker .

Sunroof will not work

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:

(1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay(1) Park Lamp Relay
(2) Courtesy Lamp Relay
(3) Retained Accessory Power (RAP) Relay
(4) Power Seats Circuit Breaker
(5) Power Windows Circuit Breaker
(6) Inadvertent Power Relay

(8) Headlamp Ground Relay
(9) Driver Door Unlock Relay
(10) Door Unlock Relay
(1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay (1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay

Buick Regal power windows and radio don't work

Check fuses Fuse number 37 in the passenger side fuse box... it should be a 15 amp fuse that is blown and actually controls both.

1998 Buick Regal LS - all 4 windows will not work from master control or individually. Could this be something as simple as a fuse replacement?

Yes. It could also be dirty electrical contacts in the switches. Worst case is that all four regulators have failed, but not likely if they went out at the same time.

Where is the fuse to the sunroof?

The main fuse block is located in the underside of the instrument panel, in or behind the glove compartment. Remove the access cover in the glove compartment to access the fuse block. Spare fuses and a fuse puller should always be kept here. Various convenience connectors, which snap-lock into the fuse block, add to the serviceability of this unit.

You will find the fuse for the sunroof in thsi area.

No power to radio, windows, or sunroof

best advices would be to check your fuses in the cabin or under the hood.

or

your grounding cable from battery or chassis is either loose or corroded. check your battery terminals and make sure they're clean. i had the exact same problem when relocating my battery from the front of the car to the trunk of the car. my ground cable was loose and the electrical circuit didnt seem to be going through the cycle.
