How do you replace a front turn signal bulb for a 2000 sts Cadillac?
How do you replace a front turn signal bulb for a 2000 sts cadillac?"
ANSWER:
The 1990's Cadillac Seville STS vehicles come with (2) independent blowers installed from the factory. The largest blower is the front blower. It is located in the center of the dash and can be accessed from the engine compartment. To remove it, you must cut the hard plastic/rubber shield holding it in place. (YES! You heard right, I said cut it.) It's designed by Cadillac to be removed this way. Cut along the dotted lines. Funny, yet true. With this blower out of commission, you can not get heat or defrosted/de-iced windows cleared. Won't happen.
The other blower is a smaller blower located between the driver/front passenger's seats just behind the gear shift housing. This is controlled by the rear passengers not the driver. This unit will not create enough heat to heat the car. It's heat/cold source is fed by the larger front main blower. Both work independent of the other. When one goes out the other works and vice versa.
Where is the coolant drain on a 1998 cadillac northstar engine?
The easiest way to drain the coolant on a Northstar is to pull the lower radiator hose off. There is a petcock on the lower left (driver side) of the radiator but it's almost impossible to get to without a special tool.
How to change thermostat in 1997 northstar cadillac 4.6?
The thermostat in a Northstar is located where the lower radiator hose enters the water pump. Drain some coolant, pull the hose, remove the themorstat housing, pull the old stat, and pop in the new stat. Reattach the housing, the rad hose and fill the surge tank to about 1" below the filler neck with 50/50 mix of coolant and distilled water.

Why wont your remote start on your 2006 Cadillac STS work?
Ensure the car is locked by pressing the lock button.
You must lock the car with the remote before attempting to start.
Also, you must have Remote Start turned on in the personalization menu. Remember the interface is a little wierd but all you do is press the bottom center swith until Remote Start shows, press the lower right (check symbol) button and if it says off, change that to on with the left arrow button/s. Then hit the check symbol once more and remote start will be enabled.
How do you program the remote of a 2006 Cadillac STS?
You have to take it to a dealer and have them re-program it. My husbands dad works for a dealership and we tried to have them tell us how to do it but I believe they have to hook it to their computer to do it.
How do you remove a northstar engine?

How do you change radiator coolant on a 1997 Cadillac De Ville with a North Star engine?
There are a number of "vehicle geometry" issues mentioned here. If you want the short answer to the question as stated, see the bullet near the end. The difficulty lies in the fact that there is no really direct route from the petcock - which is near the bottom, driver-side, inboard, face of the radiator - to a receptacle beneath the vehicle. (If you didn't know where it was - it is not your fault. It is well-concealed from above by other connections to the radiator. You can find it, but you need to know where it is first... ;-)) ) [I don't recall if draining via the petcock is blocked by the sheet metal panel at the bottom or not. (I am all but certain that it is blocked in this way - Otherwise, I would have found this operation easier...) You will need to remove from the bottom of the vehicle: a (full radiator width) plastic panel having three hex-head screw fasteners; and the driver-side connections of a 'hardware-paper'-ish sheet of material attached to the body from below, by a number of plastic press-together, two-piece fasteners - in order for you to have a shot at the petcock from that direction. I opted to remove the fasteners non-destructively, as the OEM parts are never cheap (sometimes similar fasteners can be found at auto parts stores). In addition, I suggest that you not expose that 'hardware-paper' item to any more antifreeze that is absolutely necessary. (It will sag, and be difficult to keep in place after such exposure.)] You may be able to attach a rubber hose to the petcock, and use it to drain to a container, but I chose to put a big round plastic 'pan' underneath. [Even if you use a plastic tube, you still need to be able to open the petcock - Not easy!] To open the petcock from above (standing - facing the vehicle), you probably need to find someone with hands the size of a three-year-old's; those same hands possessing the strength of an adult male; and arms the length of a person 6'9" tall! (I really wish I was joking about those 'specs'...) The petcock is very hard to reach, and in the end, I chose to do it 'brute-force'. I placed a pan underneath, and disconnected the lower radiator hose. I don't believe that there is a realistic non-messy option - Although I expect that this was the hope of the question. I am unaware of a tool that is designed specifically to open the petcock from far above, but if one exists it would have two prongs in the horizontal plane, and the ability to control their rotation about the horizontal axis, by actuating the turning from a distance of about 24"-30" in the vertical direction. [If you have a pair of 14"+ needle nose pliers, you might be able to place the jaws on either side of the petcock and twist it open (assuming they don't break). (Get under the vehicle, and bring the pliers in from 'vehicle-rear', perpendicular to the intended direction of twist.) In my case, the petcock was so tight, that it took a pair of channel-locks after removal of the radiator!] A cleaner approach might be to pump the fluid from the reservoir with the engine running, but I don't know how much fluid you could remove that way either? (And some of it will be hot - Not so safe!) * I vote for removal of the radiator hoses but only after removal of the under-body fabric! Get a wide pan and let it fall through. It's dirty, but I didn't have a week to get the petcock opened... ;-))
Where is the fuse located on a 2000 Cadillac sts for the reverse lights?
It's located in the rear fuse box (under the rear seat cushion next to the battery). Just pull up the rear seat cushion, locate NSBU (10 amp fuse).
How do you replace starter on 1997 STS Cadillac?
The starter is located under the intake manifold. You will need to remove the EGR tube and the intake air tube from the throttle body. Remove the bolts around the perimeter of the intake manifold and from the passenger side of the engine compartment you can lift the intake up far enough to gain access to the starter. Remember to disconnect the battery negative terminal first. I have used a bungee cord to hang the intake in the air while working on the starter. Remove the two wires leading to the starter and then the two 13mm bolts securing the starter to the engine block. Pull the starter out from under the intake manifold and install the new starter in the reverse order. The intake manifold gaskets are reusable.
Sounds to be alternator. Take somewhere to have the charging system tested.
