It's only a work truck,they want $500.00 to fix. they all say they have to pull the dash out,but there are 7 screws under the heater box. It looks like the bottom of an oil pan. if i remove the screws,woundn;t it expose the heater core??. or can I cut a hole out of the box to get at it and epoxy the box back together?? I don't care what it looks like, it's only a work truck. thanks john
The problem is one of accessability. The heater core is wedged in between to halves of an air distribution case and held in position with two clamps. If you remove the lower cover, you may be able to see the heater core, but you may find that the tubes that protrude from the side of the core will prevent its removal. The normal procedure is to discharge the A/C system with the proper recovery equipment and remove the entire heater box as a unit. Cutting into the case may damage the doors and actuators that control the blend-air and mode operations of the unit as a whole. I had the same problem with my 78 LeBaron, and the dash assembly had to be removed to allow the heater box to come out.
