SOURCE: Replacing front turn signal bulb on 2006 Cadillac SRX

wow i feel sorry for you because Cadillac designed this bulb to be a don't get to bulb but OK here's what you do take the bottom cover off or skid plastic panel under neath the front end theirs little plastic clips holding it on just get come dikes and don't cut them but just use it to help pull them out. after you get that off use a flash light and locate your light housing you should see two screws holding the house in i think those screws are 8mm i cant remember remove those two screws and be careful the metal from the bumper cuts you pull the light housing out and remove all the screws around the housing and open the housing up replace the bulb and make sure your contact to the bulbs clean and then reassemble the way you took apart. if you cant get it well then best bet is take it somewhere i know Cadillac charges an arm and a leg so you can go somewhere else.

You would be better off going to a Cadillac Dealership and paying the diagnostic fee. Spend $65 to find out what the real problem is rather than replacing parts until the car runs properly. This way you get it from a Cadillac Technician. Once you know what the problem is you can decide on where you want to have it service. Because you are paying for the diagnostics you shouldn't feel obligated to have it done at a Dealership. Please leave me good feedback if you feel this has helped.

First you have to take out the one and only screw in the rear hatch door - it's where the hand pull down is you use to close the hatch.
Then you have to pop all the plastic clips all the way around the plastic door panel, trying not to pull them out from the frame . If you do pull out the white plastic plugs from the frame you better make certain you take them off the plastic housing and insert them back into their frame holes - or you will never get the housing back on.

Once you have the housing loose disconnect the inside tail gate light wire to remove the whole thing. Then you have to remove 7 to 8 nuts from the back of entire License plate, back up bulb housing using a deep socket to get in there. Work it loose from the rear of the car and it will come out just enough to work on the lights.
This is tricky since the screw mounts don't give you much room to work with.

Once you have the license plate and back up bulb frame loose you will see the two housings for the license plate bulbs on top.

Slide out the license plate bulb lens and twist the bulb connection to remove the bulbs.
Replace both of them - you don't want to do this again in a month when the other one blows.

OPTIONAL:
Once you take out the bulbs you might see that the housing is melted where the bulb wanted to burn through. Drill two small holes one is each end of the housing before I put everything back together to release some of the heat.

Reverse the whole process to put everything back together. It's not easy.
Make sure you insert the cables through the opening for the hatch handle or it will kink and not work properly.

The bulbs come in a two pack of cost $4.95 .

SOURCE: Changing fuel filter on 2004 Cadillac SRX

If you go to the auto parts store they should have a fuel line disconnect tool that has a 5/16ths end an a 3/8ths end. The tool is shaped like an X. Before you start you need to pull the fuel pump fuse under the front of the REAR passenger side seat while the car is running and let it stall. it will release the built up pressure. This is important unless you want gas to spray every where. Then take the tool and start with the end of the filter with two lines. Place the appropriate end of the tool over the smallest inlet, push the tool in then pull the line towards the filter and then push the line away and it should disconnect. Do the same with line above. Then you can use the two appropriate size wrenches to disconnect the outlet end. reconnecting the new filter is simple just make sure your quick connect lines click in all the way and you tighten the outlet line well, I think its like 22 or 25 ft/lbs.
