Deathlocke

I own a 1996 Mercury Sable this morning the Electric Windows and Door locks quit working. I started the car this morning and rolled down the windows. My daughter drove the car to town and when she got home she turned the car off. I took the keys and turned the ignition on and rolled the Windows up then I turned the Ignition off and when I tried to lock the doors the Electric locks didn't work. When you hold down the lock or unlock switch the there is a wierd squealing sound coming from a set of 2 relays inside a little box under the Dash labeled Relay 1 and Relay 2 I did check the fuses and they are NOT blown something is making the relays squeal. I then decided to try the Electric Windows and now they are not working now either. Can anyone help me out here? Does any of this make sense? It seems like a fuse but it isn't. Does anyone know what I mean when I say that there are 2 Relays in a seperate Junction box all by themselves with a cover that is labeled Relay 1 and Relay 2. If so why do they seem to squeal when you hold down the Lock or Unlock Switch. Could it be the Ignition switch itself? Does anyone have any idea what is going on here both the Electric Locks and Electric Windows quit working at the same time. Both worked just fine not 2 minutes before I tried to use them. Can Someone please tell me what I need to do to fix this Problem I only have the one car and I cannot afford to take it to a Mechanic.


Country: United States
Make: Mercury
Model: Sable
Year: 1996
Engine: 3.0 Liter V6
Already Tried:
I checked the Fuses that were listed in the Owners manual. I also noticed that when you hold down the Switch either in the Lock or Unlock mode there is a Squealing sound that comes from a little Box with 2 Relays inside with the cover Labeled Relay1 and Relay2. If you physically touch the relays you can feel the squeal coming from them. I tried pulling both relays and swapping them one for the other and they still make the squealing sound

Here is problems Number 2

Every Time I start my car it Beeps 25 times in 5 Beep Intervals. I also ended up pulling the Dome light because on a couple occasions it came on and stayed on and run my battery Dead so I pulled the Bulb. Also the Door Ajar light would come on and stay on every once in a while. I read somewhere that this has something to do with the Airbag Sensor. Is this true if so what do I need to do to fix it. The Door Locks and Windows are a more Important problem due to the fact that the weather is starting to warm up in Michigan and the car can be a Sauna. Any Help will be Greatly Appreciated...

The dome light staying on has to do with sticking door ajar switches. Spray the latches with a good penetraiting lube (WD40 for example) and open and close the door several times. Repeat until the dome light shuts off when closing the door. The group of 5 beeps should be accompanied by an inop. Airbag light.

NORMAL OPERATION The AIR BAG indicator is designed to light for six(+/-two) seconds when the ignition switch is turned to the RUN position. This initial six seconds of air bag indicator illumination is considered normal operation and is called prove out of the air bag indicator. If there is an open in the air bag indicator circuit at Pin C2-11, Circuit 608 (BK/Y), a no air bag indicator fault will occur and this prove out will not be seen.

If the computer in the air bag diagnostic monitor detects an open in the air bag indicator circuit and if another system fault exists, then the air bag diagnostic monitor will turn on its internal tone generator (beeper). The beep pattern is five sets of five beeps. The pattern is repeated every 30 minutes while the ignition switch is in RUN position. The five beeps do not indicate a Code 55 or any other code. The indicator circuitry must be serviced before the diagnostic trouble code can be read.

The air bag diagnostic monitor requires power at Pin C1-6, Circuit 298 (P/O) to energize the AIR BAG indicator circuit properly. Loss of ignition voltage at Pin C1-6, Circuit 298 (P/O) due to open circuit or short to ground will result in a continuous air bag indicator (see ½Pinpoint Test D», Normal Operation, for more details) due to the ignition voltage applied to Pin C2-19, Circuit 640 R/Y).

If the air bag diagnostic monitor is disconnected or not firmly plugged in, a shorting bar in the black air bag diagnostic monitor harness connector C2 shorts Pins C2-10, Circuit 57 (BK) and C2-11, Circuit 608 (BK/Y) turning the lamp on continuously (see Pinpoint Test D, Normal Operation for more details).

POSSIBLE CAUSES
An Inoperative Air Bag Indicator Circuit Can Be Caused By:
A burned-out bulb or open wiring in the air bag indicator circuit.

For the windows and locks start with checking the door jamb wiring inside the boot. You may have a broken or breaking wire.
