Dodge Caravan 2003 airbag and engine light

Dear,
Our a/c was leaking we changed the compressor where it was leaking but I think we need to change the lines too as it still leaking. Since we changed the compressor now these lights coming on and off. I tried unplugging the battery few times but it only work for few days. sometimes it goes off by itself and then few days later comming back. I took it to mechanic and he changed some thing from the airbag and cleaned the evaporator but the problem came back.Please help me.

Sounds like the HVAC control head needs to be recalibrated. The procedure is fairly easy, Heres how its done:

CALIBRATION/DIAGNOSTICS TEST ENTRY
TO INITIATE TESTS:
Set Blower motor ON HIGH
Set Mode position to Panel
Set Temperature to Cold (Both slide pots if equipped)
Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light)
RESULTS:
All LED's will turn on for 5 Seconds
Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cooldown test is running if A/C and RECIRC are alternately flashing.
Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit.
After all tests have passed, Calibration Diagnostics and Cooldown can be run separately.

After that the lights should go out and everything should work properly as long as everything is in proper working order.

Good Luck

Why is the airbag light on in my dodge caravan sport 2003


Normally the light comes on when airbag fuse is blown. But it could be a bad airbag sensor located at the front of the vehicle. Check fuse first, if that's not it, I would recommend taking it to a mechanic to have sensor changed. They are very delicate sensor and could deploy airbag if not done carefully.

1996 caravan how would i know if the watchspring is bad?


It is called the "clockspring". You were close. Normally when the clockspring goes bad, the airbag light will come on and the horn is also affected. Not sure why the engine light is on. I think you are on the right track. There is a recall for the 1996 caravan for the clockspring problem but it only is for vehicles with 70,000 miles or less.

1997 Caravan Airbag like comes on intermittently.


ok, if the airbag light is on, there is a fault with the unit, your concerns are valid, if it has a faulty sensor the airbag MAY fire for no reason or not fire when you actually need it. if it has a recall on it, take it to the dealer so they can rectify the fault.

Recalls are a warranty repair from the manufacturer if they try to charge you scream the joint down

Dodge Caravan 2003 engine light and airbag lights are on and off?


when you undo the battery cables all you are doing is reseting the computer and not erasing any codes. I willing to bet that all it is a blown fuse for the airbag or you may unpluged the wrong terminal when changing the compressor. double check
