1994 Mercury Villager lighting problems

2 front engine manifold bolts sheared off, causing exhaust leak into vehicle and possible head warping problems in the future.the rear tail lights have blown bulbs on an average of 4 a year ,once resulting in a rear end collision. My ignition switch is so screwed up, it is impossible to remove the key safely so I am forced to leave it in at all times.my wiper/turnsignal switch has been a joke from day 1, the techs couldn't figure it out until the warrantee was over and tried to charge me for it.

The rear lamp stops working looks like the metal in the lamp socket deteched from the plastic socket. The light bulb keeps falling out. Contacted the dealer and ford and they were not able to resolve the issue.
