Fuse, motor, switch, bad wire?

That code should be left rear(Drivers side rear) wheel speed sensor short to ground, Check to see if wiring has worn thru and is contacting metal some place. GM had problems with water getting into wiring harnesses in rear causing shorts.

It is located on the fuel rail in the engine compartment, fuel rails are on top of the lower intake.

Have someone push down on the hood, as you try one last time to release it, from inside the cabin Once open--clean & lube the round part with the spring around it, on the hood & all moving parts of the lower hood latch, where there are levers & pins holding them

check the ground wire on the blower motor ... that usually stops the motor when everything else is ok.

If you mean ECT (Engine coolant temperature) sensor, yes it can. The ECT is responsible for turning on & off the radiator cooling fan. However an ETC (Electronic traction control) sensor typically wouldn't cause the engine to overheat. However if there is a code in the engine computer it can turn off the traction control. So if the ETC is turning off it may be a result rather than a cause. You'll need to check for codes in the engine computer & if there is one for the temperature sensor you most likely will need to replace it but you'll also need to check the coolant level. If it is low you obviously have a leak. FOOT NOTE: This engine is well know for its HEAD GASKETS leaking coolant. If you are having persistent overheating conditions & can't seem to locate the cause ie; water pump, radiator, hose ect. you most likely will need to have the head gaskets replaced... & that isn't cheap. Hope this helps. FarrouT!

Hi, Don't risk yourself, call a mechanic now because you did everything already let the mechanic do his stuff with your car. Remember, your life depends on you.

Hi, Overheating can bring your life to risk so why waste your time bring it to mechanic to have it double check. Take note your life depends on you upon driving.

Check your oil dats da only other solution to this problem your car might be burning oil and cause it to run hot

Does the vehicle have auto headlights? if you can manually change the headlight setting to manual check and see if the ligHts still go out. if it does the same thing I would think the sensor is bad. it's

I seriously doubt that it IS vaporlocked ... check fuel pressure and you'll probably find that it's too low.

in the fuse box and there are more than one. if there at all, (options)

I know it sounds vague, but with so little info, look at fuses. Sometimes a fuse will blow with age, but most times it's a short. It's best to buy one of those fuse testers as it's not always easy to see if one of the plug in type is blown.

Check for blown bulb or fuse.

On a cadillac deville in the front door.an in the Seville it's in the b-pillar above seatbelt retractor.

I can't advise on the type of coolant additive (I don't know your model) but in general if the coolant level is OK already then the additive won't explain this overheating. It could be - head gasket leak to the coolant jacket. There is a cheap test a mechanic can do for combustion gases in the coolant - faulty temperature sensor unit -slipping drive belt to the fan (if fitted) - thermostat stuck closed

if you have a key try to lock then unlock door before you get in this tells computer you have key and might work the remote turns it on and off maybe try a shop that installs remote starts ask for a universial remote or google 99 deville fuse diagram hope this helps good luck

Yes, it should reset the memory, I know it does on my deville, so it should be the same on an eldorado.

Try on the front of vehicle behind the front impact bar. Also try on the right front of the engine compartment, behind battery.
