That's normal, when you start the engine, every thing will go off till engine start's, need all the power from battery for start to work right.

2003 GMC Envoy. I have a different radio in it. My front door speakers work but my back rear door speakers don't work. What could that mean?

My 2004 envoy will not start. A couple nights ago the lights on the dash were going crazy on and off. I would lose power on the radio and the dash gauges would lose power (fuel, battery, water) they...

Check the connections at the battery. Loose connections or corroded connections will cause this same symptom.

It is not uncommon for side terminal batteries to also have a problem internally between the mounting button (the place that the cable end bolts to) and the internal connection to the battery.

What sounds like what is happening is the connection is good enough to power up a light load, dash lights, gauges, radio, etc, but when a heavy load is demanded the connection heats up and looses continuity.

I see this issue more on fords but I have seen a fair amount of GM's with this issue.

What could be the cause of my 2008 envoy battery not charging? it may sit for one day, the next will not start.

you may have a short in the car wireing or just a dud battery,, if the altornater is leaking back that would drain the battery as well try taking off a battery lead and let the car stand for a day or so,, if it starts right up its not the battery there is a drain in the car,, but dont take off the battery if you have not got your radio coad as you will lose the radio

I have a dead radio in my 2004 envoy. no

there may be a small inline fuse at the back of the radio itself.....you will see it when you remove the radio, this is to prevent overload
