Windows open simultaneously and randomly, when car is shut off

It's only used on cold start to help the Catalytic converter light off . The check engine light will be on all the time if you disconnect it .
The Secondary Air Injection (AIR) System aids in the reduction of hydrocarbon exhaust emissions during a cold start-up. This occurs when the start-up engine coolant temperature (ECT) is between 5-50°C (41-122°F), and the intake air temperature (IAT) is between 5-60°C (41-140°F). The AIR pump operates 5-60 seconds after start-up.
The powertrain control module (PCM) activates the AIR system by simultaneously supplying grounds to the AIR pump and the AIR valve relays. This action closes the relays' internal contacts. The AIR pump and the AIR control solenoid valve/pressure sensor assembly are in turn energized, the pump runs and the control/shut-off valve opens.
The AIR pump sends pressurized fresh air into the pipes/hoses through the open control/shut-off valve, and into the exhaust manifold. The extra air accelerates the catalyst operation, helping it to reach operating temperature faster. The AIR pump remains ON for a short period of time after the control/shut-off valve is commanded OFF. When the AIR pump is commanded OFF it will not run or be activated until the next vehicle start. When the AIR system is inactive, the closed AIR control/shut-off valve prevents air/exhaust flow in either direction.

causes could be - Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

replace the latch.?
see the part here. look it up.
find the part that is bad, and replace it
or get someone who can. (either)

You don't mention HOW she "puts the window back up" - does the power window work OK when raising or lowering the window.
There may a short circuit causing the window motor to turn on.
Let me know if the window operates normally sometimes; and whatever information or description you might have.

Here is the definition of the code.

For the A/C relay, under the hood, the relay box should be on the passenger side right near the window wipers, open the panel and check for the relay fuse. The main relay is in the car under the dash right by the drivers left leg.

I, myself own a 1993 Cadillac Sedan Deville. It has over 150K miles on the odometer and has over time had a myriad of parts replaced, mostly by me. One day, for reasons unknown, the window in the driver's side door decided not to work. Like you, all other windows remained fully operable in both directions. While the switches can fail they are, as a rule, quite reliable for long periods of time. When trying, for some time, to get the window to operate, without success, I thought, let me think about this. Upon reflection, I decided that although switch failure is possible the odds of both sets of contacts, raise and lower, failing simultaneously are small.
The next possibility is that the window regulator which is what the manufacturer calls the mechanism, has developed a motor problem. These are DC motors and I don't know whether they have a wound field ar a permanent magnet field. Assuming a wound field it is possible that the last time the window moved under power the motor stopped with a brush either stuck or in contact with a "dead spot" on the commutator. Assuming the latter and with the window fully up I opened the door, pressed the switch to lower the window and while holding the switch in the down position I simultaneously slammed the door. Voila!!! The window went down and became fully operable once more. It has been operating as designed ever since; about 8 months now. Give it a try. Window regulator assemblies are dear and the motor is NOT available as a separate part. Good Luck!!

hav car code scanned at a discount place--if u hav leak then its gettin hot n sensor detects it shuttin motor down

hello,first try to clean the window glass railing with cloth (a bit of oil) try to operate your window once a week if your car is not use,if possible do not force your window motor in downward or upward position,maybe the limit range in your motor is locked,resulting the window motor is stuck,ty

have you shut car back off and restarted it/
