automatic side door not opening

It's a common problem with the T & C. There is a sensor in the door system that needs readjusted but the problem is if it's set to work in the summer it probably won't work in the winter or vise versa. Because it's usually warmer than about 32 degrees here I leave mine adjusted to summer. It will work once the system warms up so if you run the rear heat it'll help it to work. Can drive you crazy but it's best to leave it set for summer unless you live in northern Canada.
