Question about 2005 GMC Sierra Denali

TBC (10 amp) fuse is blown. Went to replace it and barely got it in and it blew again

I noticed when I went to unlock my truck, key-less remote wouldn't work. Also nothing on my steering wheel will operate nothing.So I was tracing down the fuses and the TBC (10 amp) fuse is blown. Went to replace it and barely got it in and it blew again. Any suggestions would be appreciated. Really can't afford to take to a shop.

SOURCE: Steering column moves up & down, not the adjuster!

There is mounting brackets that hold the column in place, These brackets are either missing screws/bolts or are worn out and need replacing. Some times these brackets have replaceable plastic shims that wear out. It's also possible that you can place either a plastic or rubber homemade shim into worn brackets to take out the play.

SOURCE: shuts off while driving. no fuel pressure. pcm fuse blows/ fuel pump relay inserted.

SOURCE: Electrical Problem - dead battery

Sounds to me like you may need a new rectifier put in the alternator,a shorted diode in the alternator could be powering up things that should go dead with the key in the off position.To prove this,instead of pulling the fuse,take the plug out of the alternator and if all is well,you have your answer.

So what do you have for voltage at the battery? Sounds like the alternator went bad. There should be around 14 volts at the battery with the engine running. Anything less and the alternator would be the first thing I suspected.

I have 2 thoughts. One odd thing I found several people found that there steering wheel was not locked(you could turn it side to side) they turned wheel till it locked in position and it solved the problem with anti thief and the car cranked. The other thing I had the same problem with my 06 cobalt. The magnet in the key was bad/weak. If you have a good less used key try it in the car. It worked for me and I went to dealer and had a factory original key made for my wife to use. She drove the car all the time. Her key gave the alarm and mine was fine. The new key for 06 was 35 dollars but the price depends on your car. My 13 Chrysler cost 200 dollars.

My alarm wont turn off. my car wont start. its a 2004 tiburon.

With alarm activated your ignition is disabled.Find the combination to disable it.With GM's you hold opposing buttons on the fob till it beeps twice. The dealer should help for no charge.

Steering wheel won't lock - neither will the doors

sounds as if the locking mechanism is wearing out or not making the proper connection to the steering wheel
