hey guys so when i was driving my gtp today i tried to put the air on. when i move the fan switch from off to 1-4 the headlights turn off as well as the screen that displays oil life, mpg, fuel used.... but when i switch it to 5 the screen turns back on as well as the headlights. When switched to 1-4 air doesn't come out of the vents but on 5 it goes on to how it usually would. Any ideas on whats causing this?
 


do a search on ignition switch, see if you find others w/ similar issues, & solution=new ignition switch. BTW, for your reference in doing your homework, the display above radoi is called DIC (drivers info center). If you decide to diy ignition switch, look for link/write-up from 'sparky', got me thru mine. Good luck.
 
try unpluging the blower motor resistor and see if it still does it if not it is prob a resistor right beside the blower motor under pass side of dash
 


started acting up again...... changed the resistor didn't fix it... thinking the ignition switch? whats the way of making sure its no good
 
I have same prob, got a brand new resistor in and it didnt fix it, gonna do ignition switch sometime this week... Let me know if you do yours before me and it fixes it.
 


this is the wright up i used and it worked great..

BEFORE BEGINING THIS REPAIR REMOVE THE NEGATIVE TERMINAL FROM THE BATTERY. IT IS NOT POSSIBLE TO DO THE REPAIR WITHOUT DOING THIS.

Look inside the slot where the tilt steering knob is located. There is a black metal piece where the knob inserts into the tilt mechanism. Pry it back slightly with a small screwdriver. One from an electronics tool set will work. While you have it pried, pull the knob out and it should release.

Remove the two screws from the bottom of the steering column cover and remove the cover.

Remove the two screws that hold the top steering column cover in place.

Insert the ignition key into the key cylinder and turn the key clockwise to the start position. Nothing will happen because you have disconnected the battery prior to starting this project. Lift the top steering column cover being careful not to break it because it is still held in place by the ignition key cylinder. You will see with your mirror near the back end of the cylinder housing a small hole. Stick a small allen[FONT=inherit !important][FONT=inherit !important]wrench[/FONT][/FONT] in the hole, this will release the key cylinder so that it can be pulled out. Once the key cylinder is removed the column top cover is free to be removed.

The black box below the key cylinder with all of the wires coming out of it is the ignition switch that you are changing. Look at the switch you have purchased for this repair. Notice that the small white plug with two wires attached has a tab on the side that can be pushed down, this is the release for the plug-in. Using your mirror you will see that plug-in against the ignition switch housing where it plugs in. Using a small screw driver press the release tab in against the plug and rotate the plug 90 degrees to the right to remove it. To do otherwise may break the plug.

Remove the plug from the white key release device by inserting a small screw driver and pressing the release tab on it.

Undo the two screws holding the ignition switch.

Undo the plug at the opposite end of the ignition switch by unscrewing the bolt in the center of the plug and unplugging it. (Use 7mm socket)

There is a black wiring plug on top and a gray one on the bottom of the ignition switch plug that need to be removed. This is done by prying the center of the plug case where it meets the ignition harness plug while sliding it forward. Note: Black and gray plugs sandwich the ignition switch plug. They are the plugs for the multifunction switch.

Cut any tie wraps holding the wire harness in place and feed it out of the dash.

To install do the reverse of the above, and tie wrap the new harness into place. Be sure to properly align the key cylinder when replacing it in the housing and if the key will not come out of the cylinder there is a silver key release button at the bottom of the white device in front of the ignition switch. Press it and the key will come out. Also when replacing the ignition switch make sure that the slot in the switch is properly aligned with the corresponding part on the steering column that fits in the slot.


And don't worry.. thats just one of the things that needed to be fixed... there's many more
 
Thanks again that's gonna be really helpful.
If you didn't notice my other thread right above yours I need write-ups, even with them I somehow screw things up.lol.
If you were in the grand rapids, mi area I'd do your LCA's for ya and you could do my ignition switch.lol.
After this experience I am never going to be afraid of tearing my entire front suspension apart.
