general problems of the 1998 Plymouth Grand Voyager

My van is a lemon. All kinds of electrical problems - defogger sometimes work and sometimes not, windows won't roll down, stereo speakers sometimes works, instrument panel lights go off and on, dim yellow headlights, etc. Found pin hole in head. . . Defect in metal. Van over heated and gauge did not say it was hot. Fan went out. Now something going wrong with front end. Occasionally smell gas. The lifter head gasket now leaks oil. Van sometimes jumps in park and rolls. I can not afford to fix this stuff. . . Bail me out not Chrysler. . . .
