Open the door all the way and look for the wiring harness going into the door, if you split that wire loom open you will see a bunch of broken wires match them by color code then splice them back together. It's a tight place to work so take your time. I hope this helps. Take Care.

There's a good chance the alternator stopped working and needs to be replaced.

There is a printed circuit board that controls the delay of the motor. It is a common part that goes bad. It is easy to replace and not very expensive. Available at any national parts store.

Knock sensor is on the right (passenger) end of the engine, and will activate if at least one of the cylinders is misfiring.

it's highly very unlikely that a bulbs are faulty here . The most likely cause is the fuses then and the headlight relay and also headlight switch and dimmer switch or a wiring fault. About the only cause that is a simple fix is blown fuses.You should get a mechanic to take a look at the car and see why some of the head lights work and some are not working.

Their are no usual spots you will need to check fuses relays connectors and sensors anything can or could have been removed or jumped

You have a damaged abs sensor and or damaged / shorted wiring circuit need tiO test with a multi meter

In the box in cab or underhood. Partstore can help u on any detail

Was that fuel filter you replaced on a 2009 Cadillac DTS?

Depends on which entertainment option you have. If it has the Bose option, the amp is behind the back seat, and the sub woofer is a the center of the rear shelf panel.

When the engine is turning without ignition but is injecting fuel, that fuel and air is pumped through the engine into the exhaust where it will build up until sooner or later it will ignite with explosive force. This is what happens when there is a bad misfire due to an ignition fault. I suggest you check your spark plugs and ensure there is a powerful spark available at each spark plug.

recheck your wire routing to each cylinder. now it wont start because you been cranking it for two days

The tire pressure monitor detects any changes in the tire inflation pressure. Therefore, it must initialize and store it in its memory if the tires or wheels have been replaced, re-inflated or the tires have been rotated. You should be able to re-initialize the system by following these steps:

1. check and make sure that your tires are inflated to the correct pressure

2. turn the ignition switch to the ON position. If the low tire pressure warning light comes on, push and hold the tire pressure warning reset switch (think the switch is in the glovebox, but not sure) until the warning light turns off and then release the switch.

3. now press and hold the tire pressure warning reset switch until the low tire pressure warning light blinks three times.

4. initialization is *not* completed until driving at the vehicle speed of 19 mph or over for more than one hour. the tire pressure monitoring starts when initialization is completed.

Do you have a master key ? How did you try an program the key to the vehicle ? If you did not have a master key you need to have dealer program the key .

These are for 4.9L


P016-generator voltage out of range--Voltage is below 10 volts or above 16 volts with engine at 500rpm.

P030-Idle speed control (ISC) out of range--Check ISC for operation

A047-very low A/C refrigerant condition warning--check refrigerant level

I039-speed sensing suspension (SSS) fault--this one requires a lot of testing. Could be anything from bad connection at a strut, to bad ground, to bad strut.

I041-battery voltage too low--at 800 rpm, voltage is less than 10.6 volts

I052-keep alive memory error--means IPC lost voltage, and reset. Normal if battery was disconnected, or lost voltage.


These codes are for 4.6L


I039-loss of road sensing suspension (RSS) data--might need to replace rss module

P016-generator voltage out of range--same as above.


If you need anything else, let me know.

Also the bulb you can find here http://alibaba-homepage.com/ for best prices... as everything else. I hope I have helped. Gerard

You can check on line from the different parts stores of visit your neighborhood store. They will probably need to order it. A Cadillac Dealership may have one in stock.
