The recommended tire pressure for the 2009 GMC Envoy is typically 30 psi for the front and rear tires. Always check the label on the driver's door jamb for the most accurate information.
Start by checking the A/C fuse and relay in the fuse box. Ensure that the refrigerant level is adequate. If these are fine, inspect the A/C compressor and clutch for proper operation. Consider seeking professional help if the issue persists.

Open the hood and remove the headlight assembly retaining clips. Pull the assembly forward and disconnect the wiring harness. Twist the bulb socket counterclockwise to remove it, then replace the old bulb with a new one. Reassemble in reverse order.
The towing capacity of the 2009 GMC Envoy is up to 5,800 pounds, depending on the specific model and equipment. Always refer to the owner's manual for exact specifications.
Locate the cabin air filter compartment under the passenger side dashboard. Remove the cover and slide out the old filter. Insert a new filter ensuring the airflow direction matches the arrows on the filter. Replace the cover.
Common causes include a loose gas cap, faulty oxygen sensor, catalytic converter issues, or malfunctioning spark plugs. Use an OBD-II scanner to diagnose the exact issue.
Position another vehicle with a charged battery close to the Envoy. Connect the red positive cable to the positive terminal of both batteries and the black negative cable to the negative terminal of the charged battery, then to an unpainted metal surface on the Envoy. Start the assisting vehicle, then the Envoy.
Follow the maintenance schedule in the owner's manual, which typically includes oil changes every 3,000 to 5,000 miles, tire rotations every 6,000 miles, and brake inspections every 12,000 miles. Regularly check fluid levels and replace filters as needed.
