I have a 2008 jeep compass. I've had it for a little over a year. I recently was having trouble get the car to go into drive. That quickly stopped but now the car won't shift out of park. I have tried the switch that is beside the shifter. I can manually put the jeep in reverse, neutral, and drive. The shifter moves freely but the car stays in park. I just need to know how to fix this problem myself or if I have to take it into the garage.
