No crank

[Coalkracker]

Hi all i have a 2007 1500 thgat wont crank. The other night i drove it fine then tge next morning it wouldnt crank. Other symptoms are no radio, window wont work, dash takes a few seconds to turn on, service 4 wheel drive, service airbag, dome light doesnt come on wgen i open thge driver door but comes on when i open the back door, and there might be more but i cant think of any at the moment. The door locks and blower fan both still work. When i turn the key nothing happens. Any ideas what the problem may be?

Battery?

You don't say how old it is.

Sounds like the battery to me as well.   Did you try to jump start it?

Check the condition of battery cables and their connection battery and ground. For sure have the battery load tested

Battery is 7 months old. Its the best napa brand they had. Tried jump starting also.

[Coalkracker]

Its not acting the same as when the battery died 7 months ago. Its acting differently.

Sounds like a tough issue.  The battery is only 7 mos old, and Napa doesn't usually deal in cheap stuff.  Still, a battery can be defective by any brand.  I would start with having battery fully tested --- load, short inside the battery.  Other than that it will probably take a good mechanic to find that issue. 

Any wiring that you can see thats been chewed on by mice?

Is power getting to the spark plugs?  If not, you might be able to trace it back from there.

If it didn't try to start when you tried to jump it then there is an issue with the wiring somewhere.  Like stated above.  Make sure the cables are good.  Sometimes corrosion can be inside the cable casing and you can't see it but it stops the flow of electricity.

Can this be a possible bcm issue or should i strictly be looking at the wiring?

I forgot to mention that the line under my park reverse neutral and drive isnt there anymore to indicate which gear i am in. Also i had my rear main seal replaced 2 weeks ago. Can something have gotten pinched under there while they were working on that??

quite possibly a ground didnt get tightened or got damaged in the process

[Coalkracker]

Where is a ground in that area? I may end up having to get it towed if i cant figure this out.

You need to start a process of elimination. Check all wiring. Make sure no damage from work performed. Check starter.

Battery cables etc.
