Picture a cold dark winter night with a sleeping baby. I turn on the auto start to warm up the car and it does not warm up. As I am driving down a busy street my windshield freezes. No air is coming out of the vent to defrost the window. I had no way of seeing out my windshield. what I ended up doing was I connected a vacuum hose (my brother in law had to come bring it to me) and I hold the hose to my windshield as I am driving getting heat from the vent on the floor. I could not get a tow it was late and night and I was 50 miles from home. It was taken in and fixed to the dealership and he said that there was another Caravan in the lot that was just brought in for repair for the same problem. It was fixed but it was a pain in the ass to drive and it was so dangerous I don't know what I was thinking.
