I have a 2000 Dodge Grand Caravan 3.3l, while adjusting my power seat, it stopped working, my power locks stopped working, and ABS and Airbag lights stay on. What's wrong?

SOURCE: ABS, airbag lights on; Horn does not work

this is likely a failed clock spring and will require some special tools adn knowledge to fix. it is located in teh steering column and requires removal of air bag module.

Transport Canada Vehicle Recalls & Defects Database Transport Canada Recall # 2007169 Recall Date:  2007/05/30 Notification Type:  Recalls Audit System:  Airbag Manufacturer Recall Number:  G09 Units Affected:   51,000 Category: Minivan Recall Details: On certain vehicles the left or right front supplemental airbag sensors may crack under certain conditions, which can allow water to enter into the sensor. This can cause the airbag warning lamp to illuminate. A malfunction of one or both of the supplemental sensors will not adversely affect safety or cause a failure to comply with government standards. The single-point sensor in these vehicles, which is located in the airbag control module, is operational even if both supplemental sensors are inoperative. DaimlerChrysler has decided to launch a Customer Satisfaction Notification to advise customers that these front airbag sensors will be replaced with redesigned sensors to reduce the potential for damage. This action is not being conducted under the Motor Vehicle Safety Act.

Looks like a bad clock spring.Don't try to make this repair unless you know what you're doing!! If the airbag blows during the process,let's just say it'll ruin your day & probably the next week. I'm a chrysler master tech,so heed my warning please. I'd tell ya how to do it but I'll get sued if you get hurt.

Common issue when a wheel sensor gets faulty.On every wheel there is a sensor which informs the ABS system about wheel speed.If any of them is broken then the ABS system locks up and you get the warning light.In this case your brakes are working just as fine but you dont have ABS so wheels can block when you push the brake hard enough.Trouble code reader can tell you which one is faulty.

I have the same problem and it's not the rely or fuse... that would be too easy.

2000 Dodge Caravan ABS Light Question: 2000 Dodge Caravan. The other day my light for my air bag came on, but I noticed when it came on my cruise control stopped working and my horn doesn't work when I push on it. However the horn does work when you set off the alarm. Is it a fuse that's gone bad and if so which one is it.
Thanks for all your help.Christy
Answer: There is a device inside the steering wheel called a Clockspring. Basically it looks like the main spring of a watch. It's purpose is to insure perfect electrical contact with the airbag module in the steering wheel. Wiring for the horn and cruise control also go through the Clockspring. When the Clockspring goes bad you lose horn, cruise control and the airbag light comes on.
On 10/5/2004 a Motor Vehicle Recall, number 04V480000 was issued on this vehicle for this problem. From the recall bulletin:
Summary:
ON CERTAIN MINIVANS, THE DRIVER'S AIR BAG MAY BECOME DISABLED DUE TO A FAILURE OF THE CLOCKSPRING, WHICH IS LOCATED IN THE HUB OF THE STEERING WHEEL.
Consequence:
THIS CONDITION WILL MANIFEST ITSELF THROUGH ILLUMINATION OF THE AIR BAG WARNING LAMP, AND COULD EVENTUALLY RESULT IN A DRIVER'S AIR BAG OPEN CIRCUIT, IF THE PART IS NOT REPLACED IN A REASONABLE AMOUNT OF TIME.
Remedy:

FOR THOSE VEHICLES WITH MORE THAN 70,000 MILES, DAIMLERCHRYSLER WILL OFFER AN EXTENDED LIFETIME WARRANTY UNDER WHICH IT WILL REPLACE THE CLOCKSPRING AT NO CHARGE IF IT FAILS.
