electrical problem

I upgraded my alternator, positive/negative wires and engine ground for my subs. Now the A/C clutch won't engage and both radiator fans don't turn on. I checked the relays/fuses and they're all good. The new wiring is getting good power/ground too. Could my PCM be the issue? I've done this...

Recently my 2012 buick regal, 143k miles has been having reoccuring control module issues. Either failing or not communicating. Pcm, bcm, ebcm, pbcm, just to name a couple. It's not everytime but it is frequent. One day I could start the car and all is good. I could turn it off without doing...

Hello, I have a 2014 Verano and recently my car alarm will go off randomly, also, the door lock on the driver's side does not work. I have tested the battery and it is okay, also, I have checked all my fuses and none are blown nor are any seated improperly. I'm not sure where else to look or...

Having issues with the service vehicle soon message on the DIC of my 06 Lacrosse. I've checked every exterior light, I've checked every fuse, I have no other warnings, and I cannot figure out what is giving me this message. I took it to a dealership to have the BCM read. I had recently fixed...

I have a 2013 turbo that is giving me electrical problems. When I use the turn signal or hit the brakes or almost anything that would draw current, it reboots my radio and radar detector like the car was just turned on. It also dims the headlights. It's not every time but after driving 400 miles...

This happened twice in a few days. I got in and there were no lights anywhere on dash or dome and nothing happened when I pressed the start button. The first time I pressed the button on the door, it unlocked and I got in. I put my foot on the brake and pressed the start button and nothing...

My '13 Regal, with only 18,000 miles, developed some problems during a cross-country drive from LA to NYC. One is fairly urgent, the other is annoying. 1) About 1000 miles into my trip, I was getting ready to refuel and noticed that while my doors were locked, my fuel filler door was NOT...

I have a 2005 Lesabre with a bunch off electrical issues. I'm not sure if they are all related or not. Here is the timeline of issues. Last spring the inside trunklight quit working. no power - checked fuses all good. decided I could live without it. A few weeks latched the trunk release...

I have a 2011 CXL and over the past month I have noticed something odd happening with the URPA. Whenever I start my car in the morning and it is pretty cold, 25 degrees or below, and put it in reverse the car beeps rapidly for about 5 seconds and then stops. The beeping is identical to what it...

I have a 2002 Buick Rendezvous and I am having trouble connecting my ipod to the stereo system. Now obviously this car came before the time of standard aux inputs and since I have a stock radio there is no help there. I have tried using cassete adapters but they tend to deteriorate and give me...
