Rickys wheelchair van

Hi my 20 year old little borther Richard is in need of a wheelchair accessible van. He is wheel chair confined do to his Cerbral Palsy.His current van is 1990 chevy passenger van originaly donated by the church. It doesnt have working a.c or working heat. It is constantly breaking down and currently having major electrical issues. As well as the lift that is in it has been outgrown and fails to work at times. We are trying to raise enough money for him to get a used van with a properly working lift or ramp My 58 year old mother  takes care of him. She takes him to and from all his doctor appointments, church, and school events in the van. She already works two jobs to support Rickys many needs.Any and all help would be greatly appreciated and put to good use for Ricky.
