Help, Zippy is a 2009 Dodge Caliber SXT. Within the past 4 years I've replaced three alternators. $$$ Now that we are experiencing 90 plus weather she is having "power surges." When I'm driving the a/c shuts off, the radio turns off and so does the dash board lights. However, the engine continues to run. Within a minute or two the a/c and everything turns back on. Then in a few minutes the process starts all over again. So it can't be the alternator, right? Has any other Caliber owner experienced this problem? Zippy is sad in Lakewood, Colorado.
