Engine Performance problem
1997 Volvo S80 6 cyl Front Wheel Drive Automatic 120000 miles
The model is actually an S90. When the vehicle is exposed to hot weather, the gearshift gets stuck in park and I can't get it into any other gear to drive it. However, if I press the overdrive button, I can get it out of park, but then it shuts down all power to power windows, I can't use my blinkers, etc. Any advice what may be wrong and how to fix it?
