Hello everyone first time posting thought I would give it a shot. So I had check engine light come on and had loss of power almost like limp mode running rough. I got home checked codes and had P1125 (Accelerator Pedal Position) & P2138. I left the car overnight and the check engine turned off...

So on my Lucerne 4.6l doesnt start intermittently if i have someone push down on the relays (under hood fuse box) while I crank the car will start right up but the a/c doesnt blow cold if i push and hold down on the relays the a/c kicks on and works. put a code reader on it and it came back...

So out of nowhere, my wife gets home from work and can't turn the key all the way back and remove the keys. After some searching, i find out that it is probably an electrical issue and where to go to be able to remove the key. I started searching for the problem and found that both Lft and...

When I initially purchased my 2006 Lucerne the wipers and the blinkers worked, but the windshield washer fluid pump does not work (does not make a noise when I pull the MF switch), I inspected the fuses and switched out the fuse with a spare of the same amperage, both fuses were still good...

This car has always had this since I bought it over 5 years ago, never really thought anything of it as the functionality of the car hasn't been compromised. I have developed some electrical issues over the years and am now starting to wonder what was the intention of this electrical job and if...

I am wanting to buy an high output alternator for my 2017 buick Lacrosse 3.6 l premium. I however can not find the right information I need to confirm my choice. The website shows it fits my car but it doesn't look like my alternator. Does anyone know if this would fit my car? Are there any...

Hey guys/gals! I have an 05 LaCrosse(Allure) with the 3800 series 3 v6, and while checking around my engine bay, I came across this disconnected wire, if anyone can tell me what it is it would be much appreciated 😄👌 Apologies for poor picture quality, I couldn't upload them at any higher...

Hey folks, please help. I went to start my Regal this evening and it wouldn’t start saying “service theft deterrent.” After trying the other key and hooking up the jump box, it’ll start fine. But the touchscreen is stuck with this screen on it that goes nowhere. I’ll attach the picture. I do...

I have a 93 Buick Skylark I had bad gas ran through it before I bought it. Went through it all and got it running again, but it was stalling every time I stop. Replaced the TSS solenoid. Now it will not shift out of second gear and still stalls when I stop. **Side note: when dealing with the...

Hi guys, I have a 2010 Buick Lacrosse CXL AWD that is having some very strange issues. While I am driving, the service parking brake light will flash and my rpms will go to zero as well as my spedometer. It’s usually only for a few seconds and my car will get a bit jerky before returning back...

I added some cheap LED Switchback turn signals for my wife's 2003 buick century, and the usual resistors. They look and work great at night, however during the day they don't work as expected. The turn signals are barely visible during the day, and the DRLs are just the same dim amber rather...

I just bought this car yesterday, I was able to get the right side to flash yesterday after replacing a bulb, but then a couple hours later it stopped flashing again. I have replaced the flasher for this car and it still wont flash on either side. All the bulbs illuminate so I'm pretty certain...

Hi Everyone, newbie here. I recently bought a 2015 Buick Regal GS from auction. The car was hit on the rear left side. I brought the car to my auto body shop and they are telling me we need a module/box for the 3 wires in the rear trunk that extend off the tail light wire. I've visited my...

I have a 97 Buick park avenue and it has a problem I don't know how to diagnose. Randomly while driving it will shut off and turn back on like you turned the key off and on. Any ideas?

I have a 2000 Buick Lesabre that I am having issues with the left blinker. Started with the standard fast blinking when turning on the signal, the new part is that the Left Arrow light will stay illuminated on the dash at all times. Also sometimes I will get the warning "Is Blinker Still On?"...

Just replaced wheel hub assembly unit on 98 lesabre. Now car doesn't start. Dead battery. Drained from what I think is a short. Plugged in ABS sensor and put car in neutral to turn wheel to finish setting in the 3 torx bit bolts to knuckle. When engaged ignition to ACC position, noticed...

Hi guys im having some trouble with my regal. My old Ignition switch went bad so i decided to wire in a push button start. The only problem is that i can’t seem to get it to start. The button will turn on the accessories and attempt to start the car but the starter will never spin over. The...

Hello All, I would like to add fog lights to my new 2017 Buick Encore. I bought a model that didn't include the fog lights, but would like to add it now. Does anyone know how to do this? Any suggestions / recommendations or guidance will be much appreciated. Thanks a bunch!!

My understanding of lead-acid batteries in cars is that they are primarily for starting the car and for supplying instantaneous power when the load on the electrical system suddenly increases. I define a sudden increase as turning on a high-power amplifier or turning on the headlights. Very...

I noticed my center console light wasn't working when opening the armrest lid. I bought some #194 LEDs and the LED flickered like there was barely enough power to light it. I figured LED problem, so I inserted a standard incandescent #194. No light at all. I tested 12.0V at the socket. Good...
