Ron Ananian, The Car Doctor opens this segment with a call from Monique in Maine about her Mercedes Benz that won't start in cold weather. Then Ron has a return call from Bob in NJ about his VW's. Mike from Staten Island calls in next with questions about filters; when to replace them, what to use and how to change them. The Car Doctor squeezes in one more in his closing minutes; a 1992 Buick Roadmaster with air conditioning problems.
