GMC Acadia - Answered Questions & Fixed Issues

Hi, viewer. The interior light is powered and controlled by the body control module or BCM. However, there is an on/off button beside the main headlight switch that overrides the interior lighting function. If this button is off, interior lights will not come on regardless of any door being closed or opened.

If this button is on, interior lights will come on whenever a door is opened. If you close all doors, and if the driver door is the last to be closed, the interior lights will stay on for about 30 sec and then the lights goes off automatically. In case you left any door opened too long, the BCM has an internal timer that will shut off the interior lights automatically when it detects that a door is still opened and the allowable time has elapsed. The BCM is programmed this way to protect the battery circuit and functions. : )

The torque specifications for the catalytic converter on a 2011 GMC Acadia can vary depending on the specific model and engine type. However, the general torque specifications for the catalytic converter flange bolts on this vehicle are typically around 37-45 lb-ft. It's important to note that these torque specifications are for general guidance only, and you should always consult the manufacturer's service manual or a qualified mechanic to ensure that you are using the correct torque values for your specific vehicle and application. Additionally, it's important to use a torque wrench when installing or tightening the bolts on the catalytic converter to ensure that the correct torque is applied and to avoid over-tightening or under-tightening, which can lead to issues such as exhaust leaks or damage to the exhaust system.

My Acadia would die while I was pumping gas and then it would take multiple attempts before it would start after filling with fuel. I changed the purge valve solenoid and haven't had issues since. A new solenoid cost me $60 at autozone

We're is the release fir parking break

For issues like this you need an auto electrician with a pro grade bi-directional scan tool computer to diagnose. The misfire may just be spark plug condition, but it could be a sensor issue. It is better to pay a pro and only change the parts that need it rather than 'let's try replacing this' method of repair.

A 2010 Acadia has GM PasskeyIII security. It requires a transponder key programmed to operate with the vehicle. Your "plain key" must have a transponder encased in the plastic head of the key and was programmed to work with your vehicle.

The random no crank is likely because the immobilizer is sometimes unable to validate your key. Could be the key or a problem with transceiver in the ignition lock assembly.

If you have a second key and it has the same issue then the problem is not likely the keys but with the transceiver.

If you use a guitar string to run down the drain hole followed by compressed air, you should be able to clear the clog.

Always start in the center and spiral out is always accepted and works just fine

The regulator may be bad so check it then replace it , sometime the wire comes off the reel and it maybe hard to put it back sometimes the roller does broke

Does not use a turn signal relay flasher. Computer controlled by the BCM - body control module .

Reverse sensor is bad or transmission in reverse is locked up.
