If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana

This is what I did to solve the exact same problem.I got a pump that you can hook to a drill that has garden hose connections on it.I made 2 hoses to pump into my heater core and hook to the pump. I bought some radiator cleaner at Auto Zone and put it in a 5 gallon pail with about 2 gallons of hot water.I pumped the cleaner from the pail into the OUTLET side of the heater core.(By going in the outlet side you are back flushing the core.) I put an old cloth over the top of the bucket and let the outcoming cleaner run onto this cloth acting as a filter for the dirt coming out of the heater core and let the pump run about 10 minutes. Believe me,A LOT!!!!!!!!!!! of dirt,rust etc. came out of my heater core. The heat now works excellent! Good luck.

your heatercore is behind the glovebox, get you a cordless drill, #2 phillips, torx 10,15,20 , 8mm, 10mm, sockets, you are going to remove 1/2 of the dash, take picts of were the 200 bolts and screws come out at, it should take you 12 hours to fix it, have fun
