I did the job last night. Don't even think of attempting this with the fenderwell on. Way too much frustration. Take the tire off, battery out, unbolt all fender bolts from inside fenderwell, removed the inner to outer front brace, remove bolt from battery tray side. If you are taking it out, also remove the running light wires, otherwise at this point you can drop it down enough to work. Draw a picture of where the heater box fastners came from, only two kinds, but they are used in different spots. Unless you are replacing the fan motor, take the squirrel cage off and lube the shaft. Have fun!
