RKE opener does not work, dome lights stay on while car is off and security light on dash stays on

Sorry to state the obvious but is it possible that the door jamb button stuck on the driver side door? Try some WD-40 on the button itself and get it moving freely. If it is not physically stuck, it may always be making contact. If this is the case, replace it.

Do you hear any fans? You may need to open the computer case and look inside to see if you have any led's or fan's functioning. If you do not see any lights on the mother board or working fans, check the fan inside the power supply by looking through the fan guard. If you do not see the power supply fan working, make sure you have the computer plugged into a live outlet, and the power cord is good. Furthermore, look for a switch on the back of the power supply to make sure it is switched to the on position. If you still have no working functions of the computer, go to a computer store like Comp USA or Best Buy and purchase a power supply tester which you may find for under ten bucks. Touch the metal case of the power supply while removing the main power connector of the mother board. Always touch the metal case of the supply to discharge any static, or you could cause immediate or future damage from weakened static sensitive components. Plug the power connector into the power supply tester and make sure all lights light up. If no lights light up, you can check the fuse on the supply if it is external, or you will have to open the power supply to check the fuse. Alternatively, you can buy a new power supply which you will need to do if some of the lights on the power supply checker light up.

If the fans work on the computer and the power led's work then you may have a bad video cable connection, video card, or monitor, which will need to be checked individually. If you hear any beeps, check your manual for the description of the number and duration of the beeps which will indicate bad video or memory sticks.

I hope this helps but you can reply if you have any other questions. I think it could be the power supply with all the storms this time of year which could have killed the Power Supply which is easily replaceable.

Refrigerator works fine until the door is opened. The unit shuts down when the door is opened and it will not come back on when the door is shut, Recycing the circuit breaker will cause the unit ti start...

From your description , the control board is bad . This board is located behind the refrig , on the left side at the bottom , inside a white plastic case . Only 2 screws hold this case on , and it snaps apart to reveal the board . It costs about $ 80 and is easily replaceable . Take your complete model number with you so you get the correct part . I determine this due to when the door is opened and the refrig section lights do NOT come on ( the temp control lights also ) , this is a bad board 100% of the time .

I can not locate the cigarette lighter fuse in any of the fuse panels. Will it be named under something else for a 2005 grandam? Everything else electrical still works

Radio and ciar light are on the same circuit
The element or the case to the lighter is at fault if the radio works
The elements windings can have an open which can be seen if burnt out.
The case you need to check the continuity to see if its ok

Dead. Only lights up where plugged into power cable & LED lights

Open up the case and make sure that all the PC boards are properly seated in their slots.
Check all the ;power connectors and board connectors. One of them may have come loose during transport.
Leave the case open and turn on the power to see if the fans (case and CPU) are spinning.
Let me know if this fixes the problem or if we have to further research the motherboard. Thanks.

GigaBank 250 GB USB 2.0 External hard Drive - How to open case ?

Remove the cover plate from behind the drive (where the plugs and on/off switch are.) You have to then remove the 2 screws. After that pull on the end with the blue lights to slide the hard drive out. If you have a tower computer, you can permanently install the hard drive and it should work fine as a secondary drive. Just make sure the jumper pins are set to "slave".
