Sir or Ma'am, there may be a relay that is shorted in your car, but I cannot find the wiring diagram. If you happen to have the owners manual, please look up relays in the index to see if you can find a blower relay. If there is no relay, perhaps your switch has shorted. Until you can solve the problem, I recommend you pull out the fuse for the fan when not using the blower.

Why does my 96 Cadillac Eldorado battery keep discharging?


First step have the battery tested, a bad cell can cause a internal drain and kill the battery, if the batt is ok then check for interior lights like visors that stay on or interior light that come on by themselves at night due to defective door switches.

Something is draining my battery on my 1998 Cadillac DeVille


I suspect parasitic draw. All vehicles draw some power from the batteries when the car is shut off. Certain accessories such as clocks, radios remote door openers and alarms always need power. The normal power used is called parasitic draw.

It is always a very low draw so it doesn't run the battery down. If you install accessories like shortwave radios or plug things like inverters and portable refrigerators into the accessory socket and operate them too long without the engine running you can drain your batteries to the point where the engine won't start. If there is an electrical short in the vehicle or a malfunctioning accessory it could be drawing much more than its normal load causing a drain on the batteries. If you leave your door open and the inside lights stay on all night you could drain the battery down till the car won't start.

Here's also a good resource for your car specifically on narrowing down the cause of the drain.

I have a 1985 cadillac eldorado would the computer drain the battery if the the computer is not shutting down after the car is cut off


A computer would not draw enough current, something else is likely wrong, find out what is drawing current during shut down, the most likely culprit is the diodes in the alternator.

1988 cadillac eldorado has a new battery that only starts up with a jump charge. I think it might be the altinator or alarm ? Need the solutions


It could be the hood latch isn't engaging all the way and causing the hood light to stay on and create a drain on the battery. My grandfathers car (same year/make) had this issue and we used a bungy cord to keep it shut all the way and the problem is gone now.

1996 Eldorado shuts off while driving when brakes are pressed.


Our 96 eldorado used to do the same thing. After trying everything and several mechanics, we decided to take it to a cadillac dealer. They said it was the battery that was not generating enough power to operate some switch. Changed the battery - voila - no more problem! Hope this helps you.

My coolant fan does not go on.


check the fuse, if good then check the thermoswitch in the radiator (it's about an inch and a half in diameter located on the lower part of the radiator with two wires ) by disconnecting the wires and touching them together (again, with engine hot...at least 190 degrees) if the fan comes on, you have a bad switch. If not connect a 10 gauge jumper wire from the battery to the fan itself... With power direct from the battery (and a ground wire, if necessary) fan should run... if not replace the fan assembly... if it does run then you have a bad cooling fan relay... Hope this helps...:-)

92 eldorado coolant fans dont come on


the fans have relays that are located in the fuse box under the hood on the driver side. a quick check involves just switching the a/c clutch relay with the fan relay if they turn on when engine is hot the relay is bad. if not that means there is a bad connection or the temp probe is bad. make sure no loose or frayed wires are present. hope this helps. please rate this solution. thank you.
