My brother had his 2006 Sebring parked for 5 months and I went to start it. It was 18 degrees out. Jumped battery but engine would not turn over - weak response only. Bought one of those new battery charger jumper small pack for $90 and it worked! Amazing. Engine turned over. The emergency brake was on, I released it but when I drove the vehicle the rear wheel would not turn. Felt like the brake was still on, but geez, there was a skid mark 100 feet long and the wheel was not turning. Any thoughts?
