Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.
98.01.19
DUE TO IMPROPER BUILD SPECIFICATIONS FROM DOMETIC ON ITS BLIZZARD AC SYSTEM AIR FLOW REQUIREMENTS, THE AC SYSTEM HAS TOO HIGH OF A STATIC AIR PRESSURE. THIS STATIC AIR PRESSURE CAUSES THE ACCUMULATED STANDING WATER TO SPLASH INTO THE RETURN AIR DUCT.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
