hello there:
you may have to disassemble the door panel and check to see if the cable going to the actuator has come off if the cable is there and mounting looks OK you may need to replace the actuator its a simple procedure to do and it's just as expensive to replace the motor and actuator together at the same time the reason for this is to resolve future problems.... hope this helps thanks

SOURCE: ect light won't go off in car

When it is on it helps you accelerate faster for sportier driving, but it seems to use a little more gas when I drove with it on all the time. I would shut it off if you do not want to use it.

Set timing mode 1995 cadillac deville

Depending on the trouble codes, it may be the ECM. (computer)
You can have the car scanned for codes or attempt it yourself.
The "set timing mode" is the section of the computer program that you access to change the base timing. It should not show up on the display unless you access it.

1999 cadillac sedan deville and it keeps showing temperature of 200 plus but car is running smooth!! this temp reading scares me what could be the cause!!

Some thing too check:

Make sure coolant level is up to line and clean (not dirty, may need to be flushed out).

Make sure air flow through the out side of radiator is clear (dirt, leaves, ect..) .

Make sure electric fan is working properly (not running slow).

Check radiator cap, (no gasket tears).

Could be thermostat going bad ?

Could be coolant temperature sensor/switch (from computer) going bad?

Check radiator hose(s) (too soft, may collapse)?

ECT.............Hope tis was some help??.

97 deville The ''day'' headlights work, but when I pull out the ''lights on'' knob, or turn on the ''twilight'' switch, the day lights go out, and the regular head lights won't come on. The brake lights...

It is typical for daylights to go off when headlights are turned on. So check each headlight bulb cause it could be as simple as that. If they are OK then the switch has to be checked & power to the bulbs

I have a 97 cadillac deville why does my car over heats? and does one fan suppose to come on?

Change thermostat and use 50/50 coolant mixture only. Add coolant with car running. Fill up radiator, let everything go into engine, then add more until it is completely full. Fans only come on when car is idle for a period of time while stopped.
