https://postimg.org/image/agdjusdgl/ Click on the link. What testing have you done. Did you check for voltage and ground at the lo beams? Use a test light. In the diagram, the top wire for low beams is voltage, the bottom wire is ground. There are lo beam fuses, check those. Check voltage at fuse with lo beams turned on. It might be possible to unplug the low beam relay and use proper jumper wire on proper terminals to see if lo beams will operate. If they operate with the jumper but not w/o, check the control side of relay. Your head lamp switch and dimmer are both inputs to bcm. I can only help with testing. You have to do the testing.

Check you maff sensor it is located on the air intake plastic housing.use maff sensor cleaner.once you spray some in to the maff senor wait for it to dry .start car if it dies repeat.

I don't know

On my 2010 LaCrosse had a panel behind passenger side wheel weld that was loose, second time to dealer they found it. Almost felt like I has a flat tire by the sound!

Either turn the switch to "off" or disconnect the hot wire going to unit.

Near the gas tank under the vehicle in rear.

Battery Disconnect or Replacement Problems Your best bet , take it to the dealer .

You must remove the washer fluid tank, it is bolted from inside the wheel well I believe.

Please consult your owners manual or contact the dealer. If its not in the Owner's manual it is not an option.

Yes it is easy to fix.

Videos on youtube trouble shooting misfire's .

It could be under the right front passenger seat or center console (if it has one)

Are you sure you want to do that ? Are you guessing that's the problem ? Do you know what DTC'S - diagnostic trouble code's are ? DTC B2610 The body control module (BCM) applies a voltage reference through the instrument panel (I/P) dimming voltage reference circuit to the interior lamp switch. When the switch is placed to the desired position, the dimmed voltage setting is applied from the interior lamp switch through the I/P dimming return circuit to the BCM. The BCM applies the dimmed voltage to the I/P lamps supply voltage circuit. Do you know how to do electrical testing ? Reconnect the lamp switch assembly. Disconnect the body control module (BCM) connector C1. Using a DMM, measure the resistance between the I/P dimming voltage reference circuit and the I/P dimming control circuit. Vary the I/P dimming switch from full bright to full dim. Does the DMM, display change? Did you perform the Diagnostic System Check - Vehicle? Yes - Go to Step 2 No - Go to Diagnostic System Check - Vehicle 2 Verify that the interior backlighting does not dim. Does the interior backlighting operate normally? Yes - Go to Testing for Intermittent Conditions and Poor Connections No - Go to Step 3 3 Do the instrument panel (I/P) lamps dim? YES - Go to Step 13 No - Go to Step 4 4 Do the class 2 lamps dim? Yes - Go to Step 5 No - Go to Step 6 5 Test for a short to battery positive voltage in the I/P lamps supply voltage circuit. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition? Yes - Go to Step 14 NO - Go to Step 13 6 Disconnect the lamp switch assembly. Does all the illumination of the backlight components turn OFF? Yes - Go to Step 8 No - Go to Step 7

You need a scanner to pull the trouble codes these cars have issues with the traction control/stability control systems.
