to changing the Heater CoreBasically you pop the hood and to the very back left corner, you will see two hoses going into a box looking thing against the firewall. You will see numerous bolts and screws. You must tear that apart to get to the heater core. First step is unclamping the two hoses. Once you've done that and gotten to the heater core its just like changing a radiator except smaller. You have to undo from the supports and hoses etc.... Somewhat simple, however lengthy and tedious. (May get really frustrating!)

I'm not sure if this may be YOUR problem but when I was having my battery discharge on me, I ended up disconnecting the passengers electric seat. Again, I'm not even sure if that was the problem or if it's your problem either, but it seemed to work for mine.

I doubt it very much as they change electronics about every year.

The bellhousing, the starter, the exhaust manifords, maybe the flexplate (flywheel) and the computer, and probably the motor mounts. I'm not sure if the V6 crossmember that the motor mounts bolt to will have to be changed or not. I guess it might.

check the fuse or the ground on the heater

This is a large job and requires a manual, and removal of the engine from the car to do properly.

To change out the heater-core in a 1986 F-150, you must access the old heater-core through the glove box. You must remove the glove box by removing the screws that hold it in. Once this is accomplished, you must loosen the clamps on the hoses that are connected to the old heater-core unit. Then remove the hoses from the old heater-core and slide the old heater-core out through the opening where the glove box use to be. Install the new one using these instructions in reverse! Presto...installed! Mechanic Man
