#1490 of 1492 Interior Lighting by scruff722 Oct 09, 2006 (8:41 am)
I have a 2004 GMC Sierra *2WD, 5.3Liter V8. I want to change out all interior lighting from OEM to LED Lighting.   The Map Lights are #578 Bulbs and I am haing problems finding a cross reference for this OEM Bulb Number as well as how to remove these bulbs from their housing. I can easily remove the Light's Clear Plastic Cover and from there I am stuck physically removing the bulb?   Can anyone help me out???
#1491 of 1492 intermittant "no charge" displayed by chuck252 Oct 11, 2006 (5:15 am)
I have a 2003 2500hd sierra with 6.0L. Recently the battery light is dimmly lit with the key out or with the key on. Also, while driving the light will go brite and "battery not charging" will come into the display and will only last 5 to 10 seconds at the most. The battery died a few weeks ago and it was replaced. Ihave replaced the alternator (twice). Once at the advice of GMC, he said one of the diodes were bad. The alternator is charging 14 volts all the time even when problem shows up. It seems to show up during accelerations and large gas pedal travel but I am still trying to confirm that. Anyone have any ideas? Replies to this message: p100 (Oct 12, 2006 5:32 am)

Replying to: chuck252 (Oct 11, 2006 5:15 am) Where did you get the replacement alternator from? Was it a genuine GM alternator, or one of those Auto Zone of Advance Auto parts specials? If latter, that could be your problem. The alternator needs to put out correct number of amps at the correct voltage to function properly. Proper voltage alone does not guarantee a properly functioning alternator.
