20 Most Recent 2009 Buick Enclave Questions & Answers

You will probably find the battery under the hood on the left or right in this vehicle and the fuses box under the left hand side dash by the driver. But it may be on the right hand side under the dash too. Easy to find either way. Hope this helps and you have a kind heart to give me a good thumbs up, Raz

Just like every other warning light on your vehicle, when a warning light is on, a trouble code is stored in the computer to tell you where to begin your diagnosis. Get the trouble code read. http://ricksfreeautorepairadvice.com/check-engine-light-on-part-i/

You've got some of the picture, but not all of it.You need to know what the high and low side readings are, so yes you do need the gauge set. If the system is charged, and the low side is not dropping below 25psi, I would guess the low side pressure switch is faulty. But if the low side is dropping below 20psi when the compressor stops, the system may be low on freon. Which means you have a leak somewhere.The hissing noise is freon flowing thru the system which could also indicate a low charge.

The following lamps may be manually turned ON by placing the interior lamp switch in the ON position, or by opening a door while the switch is in the AUTO position. ?€¢ The dome lamp

?€¢ The liftgate lamps

?€¢ Courtesy/map lights

The courtesy lamp supply voltage circuit of the body control module (BCM) supplies battery positive voltage to the dome lamp, the liftgate lamps, and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps with the switch in the AUTO position. The interior lamps receive a ground at G401 with the switch in the ON position. Important: If the liftgate is opened after all the modules go to sleep, the dome light will not come on. The liftgate ajar switch input to the BCM will not wake up the BCM once it has gone to sleep, so the dome light will not come on. Once the BCM gets an input to wake it up, from remote keyless entry (RKE) or a door handle, the dome light will turn on when the liftgate is opened. If the driver inadvertently leaves any interior lamp ON, the BCM will turn it OFF after a 20 minute time-out. The courtesy lamps will turn OFF immediately if the ignition switch is turned to the ON position or approximately 20 seconds after all doors are closed. The courtesy lamps are controlled by the body control module (BCM). Inputs from the dome lamp switch and the door ajar switches are monitored by the BCM. When a door ajar switch is closed, or the dome lamp switch is turned to the ON position, the BCM supplies the B+ for the courtesy lamps. With out a factory Tech2 scan tool or equivalent an knowing how these systems work ,you best bet is to take your vehicle to the dealer or some other ASE certified repair shop !

The task requires mechanical skills and hardware such as a Cherry Picker. Without the proper tools; you cannot manage this function. In addition, you have to remove every attachment, fuel lines, support brackets, covers, plates, mounting brackets, electrical, and misc. devices. Then reassembly is difficult and you need a computer to reset the parameters set forth by Buick.
