1997 FREIGHTLINER BUSINESS CLASS Structure Problems

REAR PASSENGER DOORS OF FREIGHTLINER "BUSINESS CLASS" TRUCK COME UNLATCHED AND OPEN UP DURING OPERATION DOWN THE ROAD. THERE ARE ALSO INCIDENTS OF THE TRUCKS PARKING AT CERTAIN ANGLES WHERE THE DOORS WILL NOT OPEN UP AT ALKL. THIS HAPPENS ON BOTH FL80 CHASSIED FIRE TRUCKS. CRACKS IN THE ROOF STRUCTURE HAVE BEEN IDENTIFIED BY FREIGHTLINER AS A POSSIBLE ISSUE. WE ARE TRYING TO FIGURE OUT IF THIS IS A FREIGHTLINER OR E1 PROBLEM. THE ISSUES HAVE BEEN GOING ON SINCE BOTH TRUCKS WAS 5 YEARS OLD. SEVERAL DOOR LATCH ASSEMBLIES HAVE BEEN PURCHASED OVER THE YEARS IN AN ATTEMPT TO RESOLVE THE PROBLEM, WITH NO SUCCESS. *NM
