Hello
I have a Mazda MPV 2000 and facing two issues. I wonder if someone can advise on what to do:

1) Driving side rear sliding door is not locking up (it is not automatic). It happend in the past when temperature start freezing up. This year it happend again. As soon as temperature start to go below -15, door got frozen. When the van got warmed up, it opens up by iteself and then do not get close. I never had this issue unless it is winter. What could be a possible problem and is there a way to prevent this door freezing.

2) On a dash board panel, intermetantly airbag light is blinking. Do I need to be concerned. Any advise would be greatly appreciated.

Thanks
Syed
