Check the battery for any damages from a technician, even a short circuit in the wiring can cause the battery to drain faster,If its under warranty get it replaced as soon as possible.

What are common problems with the '89 Collection Rouge v12


Some of the most common problems I encountered with my 1984 V12 (most of which you will find on yours):
  1. Electrical wiring faults, especially poor ground connections (thanks to Lucas Electric);
  2. Misadjustment of the two throttle butterflies (tricky adjustment for mechanics who do not understand it);
  3. Engine computer failure. THIS HAPPENS 100% OF THE TIME WHEN THE CAR IS JUMP-STARTED USING A STANDARD JUMP START CART!!! DO NOT LET ANYONE JUMP START YOUR CAR USING AN A/C POWERED JUMP START CART.
  4. Failure of the fuel injector lines causing serious engine fires;
  5. Poor fuel economy, often under 10 m.p.g. in-town (nothing you can do about this);
  6. Rough idle caused by bad spark plug wires, followed by failure of the ignition coil;
  7. Starter failure (annoying and happens without warning);
  8. Leaky valve cover gaskets;
  9. Failure of the plastic cooling fan (it flies apart when it gets old... replace with a non-plastic fan if possible);
  10. Lack of performance due to the car never being "opened up." (You need to drive it hard & fast sometimes.)

Why is this happening


Before you go any further, have the battery checked. If there is an internal problem, it will create all kinds of problems like this.

Seems to be a complete electrical failure


Always start at least 80% of all vehicle checking with
the battery first

Never go by how many years or miles are on something

If some module failed to time out, your battery goes dead in,
as you said, about 3 days & check if you left the interior lights on

My cougar does not wanna start like the battery is dead but I replaced it a month ago n I tryed to jump it n still nothing any ideas could it be the starter or alternator?I'm just lookin for a place to...


Your alternator keeps your battery charged and can easily be tested for free at Autozone or Oreilly`s. I don`t think your alternator is your problem, sounds like a problem with the starter. Check your connections and electrical wires before changing your starter.

1999 cougar been setting for a couple of months tried to jump it and all i get is a continuous clicking sound when i turn the key is this just the battery needing to be charged or something else?


if the battery is the original i would replace it but yes the battery is too dead and if it is old enough the battery could be dead beyond recharging

Car wont start


Assuming power is getting to the starter fine I'd have to guess the starter is worn and may require replacement. I'd investigate the starter motor.
I hope this may have helped,

Catastrophic electrical problems


I'd check the terminal connections and twist them a little to see if they're loose or corroded.
Then follow the wires and check all other connections from the battery.
Can you jump start it?
If not it could be the solenoid or something else!
I once had this problem and finally discovered it was a melted connector under the dash on the drivers side right below the ignition.
I hope this was helpful!
Good Luck!
