You may want to check your resistor in the box under the dash before you replace the blower motor. I do have good used correct date coded blower motors, squirrel cages, resistors and even correct date coded heater cores if you need any of those just PM me. If you need to remove the box first you would need to drain your coolant and carefully remove the hoses on the firewall. Then you need to remove the control cables under the dash from the box and unplug the wiring there also. Then you can remove the fire wall retaining nuts. Go back inside next under the dash and at this time is is good to have an extra hand to help hold the unit while you remove the small J-Bolt that holds the box to the cowl plenum opening. Once the J-Bolt is removed the box assembly will come out. Be careful to keep it tilted up as much as possible so the coolant that remains in the box core does not spill onto your carpet. Remove the clips/nuts that hold the blower motor and metal support to the box. Then you need to remove the center clamp that holds the squirrel cage to the motor and you can remove the 3 nuts that hold the motor to the metal plate. At this time while things are apart you may want to consider taking the core from the box and have it cleaned and tested at a radiator shop. If i where you i would also buy a new firewall/box gasket set at this time while it is out. I do have a complete new firewall gasket set here in stock which includes gaskets for the box to firewall mounting
