Air bag light & tail light

Hello. The airbag light on my 2005 Grand Caravan came on and wont go off. Has anyone had this problem?
Is it easy to fix?
Also Someone bumped into it while parked and cracked the driver side taillight. Is replacing it an easy job or should I just take it to the mechanic. I'm laid off so I'm trying to save as much as I can.
Thanks for any help

dont mess with airbags take to mechanic expenive and senitve caution with taillight should be like two screw inside lift gate covering inside how acces most things like andrear washer bottle i think dodge has recall for check with dealer they said air bags wont deploy bad sensor see if you qualify could be free fix

Check all your fuses first, my 94 GC SRS shared the rear wiper fuse.

Airbag is recall , I just called dealer and took mine in last week, they changed clockspring for free
