That is why I mentioned it, has to do with any electronics. You are not suppose to disconnect any electronics with power still applied.Is it really possible to damage my BCM, PCM by connecting the positve lead to the battery terminal while elaving the key on?
You overloaded the stock alternator with all that gear. You need a high-output alt, if you can find one.Well after some time troubleshooting I have finally resolved my problem. So let me do my best to explain the events and the solution. Hope this helps some of you, but clearly there is a problem with the electric power steering.
Before a long trip I decided to do plugs, wires and O2 sensors before making my long road trip and due to the fact that the car was in need of a turn up. Now I could not get off the back plug wires (I cannot stress putting a lot of Dielectric Grease in the plug boots to prevent this from happening) so I decided to wait to get them off till I returned from my trip. Car drove there and back with no problems. Once I returned I removed the alternator (while doing so the positive cable sparked on the block) to gain better access to the back of the motor. I then disconnected the battery which you should do anyhow, but was fairly sure this didn't cause any problems.
After all put back together my wife called several days later saying the car was acting weird. She told me that when she gave it gas all of the gauges would flash and steering go very tight. Of course at first I thought of the spark and how what problems could I have caused. Well about a week later we received a letter from GM stating that if you are having these problems then have the column replaced. After doing so the car drove so much better but the problem started again very shortly afterwards. I didn't want to bother the dealer again so I started reading online and someone said that the tensioner was the problem. I could see this if the belt is slitting and then the alternator wouldn't work correctly. So it was replaced with same result.
Now so far I know that I lose power steering under full acceleration and under a load. Also I knew by this point that the problem didn’t occur if it was 60 degree or cooler outside. I then knew this had to be electrically and only thing that it could have been was alternator and battery. Both tested fine in the car.
Solution: I felt that because the car ran on the alternator when running I had to start there. Once this was replaced I have not had a problem since. I did go ahead and replace the battery latter because I felt it could have been affected with the weak alternator for so long. I guess once it got hot enough it just was not efficient any more. Hope this helps someone else.
**Problem noticed when mid to full acceleration(passing cars) or running cruise control and going up a slight hill that caused a load on the car causing mild acceleration.
Because the car needed a little more electrically power, the alternator could not keep up and something as demanding as a electric power steering would fail.

Whoops@greenman - the OP had all the tech gear, not blackhawk
. Caught in the thread hijacking trap yet again. My bad.Start by checking the fuses. The engine fuse panel is typically (in my experience atleast) where you can find the headlamps and similar.I need help asap. All my head lights and front turn signals wont turn on. The fog lights work tho. Idk what to do. Please help!
