well the other day i was tunning my truck on nitrous.. well i had a backfire and blew my intake.. well i replaced it and got the truck running but now i have a really bad electrical problem..

first, my keyless entry doesnt work,

my volt gauge stays at 9 volts and when i start the truck it always says battery not charging.

my driver door only controls the driver door and the doorlocks dont work.. it wont lower the passenger window or control the mirror..

the A/C controls work but wont kick on the A/C compressor

I already checked alternator and battery and every possible fuse and relay.. i've run out of things to check.. im thinking it might be the BCM since its problems in the interior but idk.. has anyone had a problem like this??

 

That sounds strange. How bad was the backfire? Did it blow **** all over under the hood so bad that it could have cut a wire somewhere?

Sounds to me like the backfire and problems could be related in that the problem caused your back fire. Not the other way around. Do you have your nos kit wired for power off of a wire under the dash? Maybe the short that is causing your problems also caused a solenoid glitch. Have you tried the nos again since the problems have started? My guess that that it probably won't work.

If you confirm that what I'm saying is the problem, take a look at where you have spliced wires under the dash----you may find your problem there.
