20 Most Recent 2009 Chevrolet Impala Questions & Answers

Before you do any of the expensive things disconnect and reconnect the wiring to the seat I had the same exact problem with my 2009 Chevy Impala and was ready to take it to the dealer when I disconnected the power cables to it and reconnected them I found that one of the Harnesses was loose and the problem was solved

Question edited for clarity. Question moved to model category. Here it says hand tight and a bit more, another says hand tight and a quarter turn. Replace the compression washer on the plug and you could use Loctite Thread locker as well. It is also possible that the threads are worn on the plug or in the sump. They are susceptible to being over-tightened. https://paulstravelpictures.com/GM-Chevrolet-Impala-LZE-3500-V6-Engine-Oil-Change-Guide/ General Guide Install the oil pan drain plug with a new O-ring and torque the plug: a. On a plastic oil pan, torque plug to 45 N·m +/- 7 N·m (33 lb·ft +/- 5 lb·ft). b. On an aluminum oil pan torque plug to 60 N·m +/- 9 N·m (44 lb·ft +/- 6 lb·ft). https://www.google.com/search?q=2009+chevy+impala+3.5+oil+plug+torque ..

I would certainly check the wheel hubs, the main bearings are in them. Also, struts or shocks could be bad or you maybe needing a front end alignment.

gas cap code p0449 ??? This is not a gas cap code ! DTC P0449: Evaporative Emission (EVAP) Vent Solenoid Control Circuit.. your best bet , take it to a qualified chevy repair shop . Wells EVAP Training with Sgt Tech P0440 P0441 P0442 etc

Yes, the starter runs off a timed relay so it doesn't crank until the battery is dead. You need to figure out what issue you have that the engine doesn't run. You need fuel, spark, and compression for an engine to run. Which one do you not have?

First off you need to read how this works . BCM - body control module is in fail- safe mode more then likely . The ingition switch is a input to the BCM . The BCM turns on relays to turn vehicle systems on . If something happens the system will fail safe to last commands by the BCM . The body control system consists of the body control module (BCM), communications, and various input and outputs. Some inputs, outputs and messages require other modules to interact with the BCM. The BCM also has discrete input and output terminals to control the vehicle's body functions. Battery positive voltage is provided to the BCM from the BCM fuse in the underhood fuse block. The module has two grounds at G 202 as well as one directly to the vehicle battery. The BCM is wired to the GMLAN High speed serial data buss and the GMLAN Low speed serial data buss and acts as a gateway between them. If the BCM does not communicate the vehicle will not start due to the inability of the engine/powertrain control module (ECM/PCM) and vehicle theft deterrent (VTD) control module to communicate without the BCM providing the gateway function. Power Mode Master This vehicle body control module (BCM) functions as the power mode master (PMM). The ignition switch is a low current switch with multiple discrete ignition switch signals to the PMM for determination the power mode that will be sent over the serial data circuits to the other modules that need this information, and so the PMM will activate relays and other direct outputs of the PMM as needed. Refer to Power Mode Description and Operation for a complete description of power mode functions. Relay Controlled Power Mode The body control module (BCM) uses the discrete ignition switch inputs Off/Run/Crank Voltage, Accessory Voltage, and Ignition 1 Voltage, to distinguish the correct power mode. The BCM, after determining the desired power mode, will activate the appropriate relays for that power mode. The RAP relay remains on for a timed period after the Ignition key is removed. Refer to Retained Accessory Power Description and Operation for more information on the retained accessory power (RAP) function. You mite want to thing about taking your vehicle to a qualified repair shop. Hooking up a professional or factory scanner to view input data to the BCM ,plus checking for DTC'S - diagnostic trouble codes in the BCM , autozone , advance part stores can not read codes in the BCM .

vent door actuator is bad. not sure how much to fix but not that bad of a job. look it up on youtube. pretty simple fix.

Your not going to be able to diagnose the SRS (Air Bag)System, without factory trouble charts to follow,way toomany codes & procedures to follow.A battery is about $110.00 & the cables are only3 yearsold,so they should be able to be cleanedI would only guess, that they didn't do anything aboutyour intitial complaint on the Service Airbag light,notfor $100.00

First of all, Alysa, that's not nearly enough information. The most common causes of engine overheating are: leaking hoses, radiator leaks, heater core leaks, a failed water pump, thermostat leak, freeze plugs leak, automatic transmission oil cooler leak and (I hope not for your sake) a cracked block or cylinder heads. Make sure you have the radiator filled with the proper amount and ratio of water and anti-freeze. Simply dumping more anti-freeze in there won't help. Check for leaks and check the thermostat before doing anything. Hope this helps. . .

try replacing it wearing gloves. oils on your skin transfer to bulb and ruin bulbs.

stop touching the bulb with your bare fingers need to wear latex gloves when installing. put some dielectric grease on the connector, be sure you dont get any on the bulb
