Top 20 1998 Cadillac Eldorado Questions & Answers

My opinion it is that it is, in fact, the driver's door switch panel and you should try replacing it (try EBay). The problem could ether be worn out switches, or there is a problem with the distribution of power to all the switches in the panel. You should be able to easily diagnose the problem by pulling the switch panel (without removing the door panel) and checking switched power at each switch at the back with a multimeter. Seat heating pads are built to flex but are a bit flimsy. As they get older and have been sat on many times, the element wiring can break in the weakest spot causing the problem. Unfortunately, to check out the wiring, you usually have to remove the seat.

Probably the shift release solenoid or the switch or relay that activates it. This solenoid usually activates when you press the brake pedal, releasing the shifter. There is usually an emergency release button that can be accessed to release the shifter in the event this occurs. Check you users manual for the location of the release and how to activate it.

Is your alternator actually charging? If you are not getting power into your alternator it will not put power out.

Usually, if it cranks good, but, won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also, check fuel injector pulse. Knowing if you have multiple issues can help? If multiple issues, I want to check for rpm signal. If no spark only, check primary voltage and ground at the coil, go from there. Check for applicable trouble codes, to check codes, yourself, you may need an obd2 code reader. I can only make suggestions about what to check, you have to do the testing.

Some times when a number of things go wrong like described, a common ground wire is not making a good connection. If you can get a wiring diagram for this car, I would check to see if there is a common ground wire for the items in question. Also I would check the multi wire connectors at the computer. Resetting these plugs sometimes can help.

There is one cam sensor in the rear head on the passenger side, as far as I know there is only one. Maybe the confusion is that there are 2 crankshaft position sensors, and they are located near the oil filter adapter

Your best bet is to obtain a Chilton's or shop manual for your vehicle and read the remove and re-install instructions thoroughly before beginning any such effort. For example, the same repair you are suggesting on a jeep Cherokee is $600 labor to remove the dashboard to get to the $40 part....... Once you fully understand the steps to get to the heater core you can make an informed decision on how to proceed. You may decide to simply by pass the heater core, sell the car and get one with working heat, and let the new owner worry about the issue. Mind you, I am NOT advocating deception, please fully disclose the issue to any potential buyer.

just wire up your new ones all together then hook it to the one wire on old horn

Good day and welcome to FixYa! First of, there's nothin to be afraid of. Its an easy thing to do. Just find the screws or it can just be a pull slide up reservoir then install the new one. Nothing serious. Hope this helps and welcome to FixYa!

You will find wiring diagrams in both Haynes and Chilton books available in auto parts stores and maybe your local library.

just screw it back in try to hold outside ring once it starts continue to tighten

I know caddys and most Eldorado yes they do have oil in crank case

Bad injector or injectors not getting proper lower..noir lights help for this

will be either a loose wire connection around the light cluster or the switck has gone , test for power to the light fitting if no power and the wiring is in good condition then i would say try a new switch

Had the same code but it turned out to be one of the coils. Cam sensor was ok

Sounds like you have a bad ignition immobilizer or maybe the chip in the key is going bad. Did you try using your spare key to the car?

NO-- it cannot be by passed as it is in the program of the unit If you cannot get the code you have wasted your money in the wreckers . I would suggest that you get a unit from a radio shop and have them install it for you and then it will work properly with no car problems.

dirty or wet sensor wires .clean them.

More likely that the turn signal switch assembly is bad.Have someone watch the tailights(or use a large mirror) to see if the bright tailight filaments come on with the brake pedal held down while you wiggle the hazard light switch.
