My 300 SEL has a different problem: not enough heat. My Tech said is was NOT the monovalve. My dealer said it has something to do with the electric push button (around $300).
My heat only works when it is on LOW. When you put the heat on HI, it blows on cold air. It really bites on a cold morning to get the frost off. What is the problem and why so expensive to fix? ------------------ '89 420 SEL '90 300 SEL '84 300 SD (sold it)
