SOURCE: 98 cadillac deville battery wont hold a charge

sounds like a 12V drain on the system, like a trunk or glove box light that won't shut off.> Could be many. many other reasons why. The way I would find the draining circuit would be to remove the neg cable of the battery. I then would connect a 12V test light between the neg battery TERMINAL and the neg battery CABLE. With a 12V drain the light will shine. I would install into the light a 9V battery powered recepticle to hold computer and radio station memory. Then I remove fuses 1 at a time, then reinstall, at the same time looking for the 12V light to go out. Hope this helps.

SOURCE: 88 cadillac deville, ac blower fan wont shut off,

Ralph,
Most common cause of this is the blower fan (proper name for the fan you refer to) continuing to run is a shorted out Electronic Climate Control Module. This solid state device replaces the older style fan speed resistor block (at about 4 times the price) This unit is found on the top of the HVAC box under the hood. (HVAC means heating, ventilation and air conditioning) The HVAC box is found on the passenger side of the firewall. Look behind the A/C's accumulator. It will have an electrical wiring plug on top of it. It will be fastened to the HVAC box with a few 7mm hex head screws. Very easy to change.
FYI, do yourself a favor and replace the blower fan motor at the same time. The Electronic Climate Control Module usually fails because the motor is drawing to many amps of current. This is because it's bushings are worn out or the brushes are worn out.
This is very common on Cadillacs and Buicks.
Charlie
PS Not sure why car won't start. Either you drained the battery or blew a fuse which controls starting the engine. Need more info regarding the "no start" condition.

SOURCE: 1997 cadillac deville delagance - anti theft device

I've got a 97 deville d'elegance that has issues similar to these. Last year the red anti-theft light came on and the car wouldn't start-took it to the dealership and they replaced the PCM? (the main brain for the system) for $900...the guy told us the wiring was so corroded he didn't want to mess with it much. Today the message started flashing on the dash that says "anti-theft problem/ car may not restart" but it still turned over in the driveway a couple times so I am hoping I can reset it. The wiring system is jacked and will probably need to replace the wiring harness completely. Doubt its worth it. Not a secure feeling with 2 babies in the back seat in the middle of winter....

SOURCE: Cadillac 1999 DeVille Battery goes dead after

You should check for voltage draws when the vehicle is off... Disconnect the negative battery termal, Pull dome light fuse,and connect a light or volt meter between the two.

common offenders are alternator diodes. These fail and cause drain.

Then you have to check, circuit by circuit, until you find the offending system.

Also, before doing anything, disconnect negative terminal and see if the battery is still fully charged after a few days...

I soldered all the connections on my stereo system and I keep blowing my 5amp fuses I have the yello wire from the head onto pos + on my then I have the black wire on neg .also my red wire is on neg.


check the wiring as the red wire may be a positive power in wire and if you have it on the negative terminal that would amount to a dead short and that would blow the fuse
consider changing the yellow from the + terminal and putting the red wire there and if it stops blowing fuses the put the yellow wire on to the - ve
if that means that the unit doesn't work then touch it back on the + terminal
if that works the solder it there

Small Wire broke off next to ground cable on 1996 cadillac deville where does it go?


If it is coming from the ground NEG post it most likely is going to another power item as its ground...normaly not tied into the operating system..if it is not effecting the operation should not be a problem but if in doubt just loosen the neg cable and strip the wire and connect it to the neg and tighten the cable..good luck...

Put my battery on wrong neg on pos pos on neg yes plonker moment after wouldn't start checked fuses three blown now replaced car will start but side lights don't work hazards or indicators...


besides checking EVERY fuse in both fuse boxes, check the multitude of relays because chances are some of them are toasted as well. And keep your fingers crossed you have not damaged a CM.
You can wiring diagrams out on the web.

Collingfans won't come on after resistor was replaced,also ac pump won't come on, have power to the relays under the hood and when they are jumped can get power to ac unit but still no fans


on the cooling fan part, disconnect the wire harness and run 2 wires from the connector to the battery, ( 1 wire to the pos 1 to the neg) if that dont work, switch the wires at the battery (take the wire on the pos and switch with the neg) if the fan still dont come on , you have a bad motor on the fan. if it does work and your relays are good, i would say you have another electrical problem

What is malfuntion code P2127?


the (app sensor)accelerator pedal position. to test unplug the electrical connector at the accelerator pedal position sensor. Using a digital multimeter and with the key in the RUN position, check the Green wire for 5 volts (pos lead from meter to green wire, neg lead to ground). Then check the black/white wire for good ground (pos lead from meter on Green wire, neg lead to black/white wire)--should read 5 volts. Reconnect electrical connector to sensor.

I have a 1996 cadillac deville and the interior lights won't go off, i had to pull the fuse.


I would check to see if the headlight switch is turned too far one way or the other.

If this doesn't solve the problem, an electrical shop can trace the problem to see if there is a shorted or crossed wire somewhere.

Could also be a bad Body Control Module.

My cadillac deville overheats a lot, why does it do that?


Check the radiator, hoses, and water pump for leaks. If you don't see any coolant loss, the problem is most likely a faulty thermostat. Hope this helped and best wishes.

Car only cranks sometimes.


Hey Keith,

(1) Clean the battery cables with a stiff wire brush
Remove both Neg and Pos cables; brush the bolt, washers,
and the battery terminals VERY WELL until shiny.
(2) If this does not clear the problem; check battery voltage
with engine running.. should be 16 volts from alternator.
(3) Check battery with load test (most shops do this free).

If all these fail; replace starter and soleniod...2 hour job.
