Has to be other nuts or fasteners. Check on the firewall side, too, behind the engine. There could be nuts or fasteners on that side.
You do have the heater hoses already removed? I think you just missed all the nuts holding the heater case. Good job getting that far, just keep looking, pretty sure there would be more than just two nuts, even one more, but check on the firewall side.

i just recently replaced mine and the temp control had burned . the dash fascia needs to be removed. the vents must come out and then remove the screws that hold it on..there are probably 10 screws.. under the vents , behind the ashtray, and behind the cruise control switch and dimmer switch.. once this is done you need to remove the 4 screws that hold the heater control unit in. the bulb that needs to be replaced lights up temp control and fan speed...you may be able to download an exploded veiw of the dash fascia...this is an involved job...but worth it at night!

SOURCE: 1996 honda civic wont start

Hi Meadors,

The clicking sound you heard most likely the starter solenoid engaging the starter. Only in this case it's failing to engage the starter. This is a classic symptom of a low battery. Here's why.

In a perfect world, when you turn the key to start:

  1. the solenoid is fed 12VDC which engages an electromagnetic coil inside it.
  2. A spring loaded steel piston inside this coil reacts to the magnetic field. It is pulled against the spring. By itself this sounds like a loud decisive CLICK.
  3. The movement of the piston simultaneously pushes the starter gear into the flywheel and sends power to the starter via heavy duty contacts. The starter draws a lot of power.
  4. The starter spins, turns the engine, the engine starts, life is good.
  5. When the key is released, the solenoid disengages, the spring pushes the piston back, the starter gear disengages from the flywheel.
In our world, when you turn the key to start:
  1. The solenoid which draws it's share of power engages as before. Click.
  2. As the starter tries to spin, the power available is insufficient. It draws all remaining power, there isn't enough left to keep the solenoid active and it turns off.
  3. Since the starter isn't drawing power anymore, the solenoid re-engages and the cycle starts over. Click.
  4. The cycle repeats. Click. A series of rapid clicks. Same page?
While a dead battery is the prime suspect, there can be other causes. Things to do:

  • Check belts, specifically on the alternator.
  • Terminal connections clean and tight.
  • In the 'Let's not over look the obvious' department: Battery voltage?
  • Get a jump. Try a jump start.
  • If a jump gets you going, it is either the battery not holding a charge or the alternator not providing one.
Even new batteries can be bad off the shelf. Especially if they have been on that shelf for a while. They may show the voltage but not the amps. This is called a 'Surface Charge'.

If you don't have a voltmeter, what you need to do now is visit an auto parts store (not a shop). Most (in the hope of making a sale) will provide free testing of batteries and charging systems.

What you need is called a "Load Test" on the battery. It simulates the load of an engine being started. This will confirm the battery is good or bad.

Then with the car running, they need to check the voltage to the battery (they will know this). If it's not above +13VDC, the alternator is bad or not connected correctly.

And if it doesn't start, what better place to be?

Let me know what they and you find out by commenting.
Best regards
Mike

SOURCE: 97 Honda Accord. Dash & taillights blow fuses.

Bad grounds cause weak dim lights and intermittent operation a positive circuit shorting to a metal ground causes shorts and blown fuses burnt connections. You need a wiring diagram for the circuit and need to trace the wires and look for a short. Or if there is no short in the wiring and this vehicle uses a module computer for the lighting the module could be faulty.

How to install a blower moter and fan


Well, here's the instructions from the service manual. The labor guide says this can be done in 1.6 hours...I don't see how, unless the instructions are wrong about having to remove the instrument panel. My thoughts are that if you are only doing the blower motor, the blower assembly will come out without pulling the dash. You probably only have to do a partial disassembly and remove the glove box and the glove box lower support.

*************************************************************************************

BLOWER ASSEMBLY

Removal and Installation

1. Disconnect battery ground cable. Remove Instrument panel. (See Instrument Panel Removal) Disconnect resistor connector. remove blower assembly duct. Disconnect motor connector. Remove blower assembly

2. Remove blower assembly screws and blower motor assembly. Remove clip and fan from assembly. Separate motor case and remove blower motor. To install, reverse removal procedure.



INSTRUMENT PANEL

Removal

1. Disable air bag system. See AIRBAG RESTRAINT SYSTEM article in ACCESSORIES/SAFETY EQUIPMENT SECTION. Disconnect negative battery cable. Scribe mating marks on steering wheel and shaft for installation reference. Using Steering Wheel Remover (J-29752) remove steering wheel. Remove steering cowl.

2. Remove instrument panel grilles and plug, or driving pattern indicator panel (A/T Models). Disconnect electrical connections. Remove instrument panel hood, instrument cluster ezel and instrument cluster. Remove hood release handle. Remove knee protector.

3. Remove dash fuse/relay block and side trim. Remove engine control module box. Remove radio console and glove box lower reinforcement. Remove speaker covers and glove box. Remove heater control panel knobs and cover. Disconnect heater control cables, and remove heater control panel. Remove illumination control knob. Remove instrument panel.

Installation

1. Install instrument panel. Install and adjust heater control cables. To complete installation, reverse removal procedure. Ensure mating marks on steering wheel and shaft align. Apply grease to contact ring and tighten steering wheel nut to 26 ft.lbs. (35 N.m).

Replacing the heater core i need to see where the screws are in the black box


Check this procedure for 1993 Ford Taurus 3.0L FI 6cyl REMOVAL & INSTALLATION
(see Figures 1 and 2)

Be sure to consult the laws in your area before beginning any procedure which requires servicing the air conditioning system. In some states, it is illegal to perform repairs involving refrigerant unless the work is done by a certified technician.

CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by the ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.
When removing the instrument panel, it may be beneficial to have a friend or assistant help you.

Hi I,ve got a 2000 Jeep Grand Cherokee, the problem I,m having is when I turn on the heating fan i get a mist or steam coming out of the vents smells like coolant could this be a heater core problem ,...


Yes, your core is leaking. The core is in the box under the dash. The procedure is quite involved. I will attempt to paste from autozone.com below:
  1. Before servicing the vehicle, please familiarize yourself with safety procedures.
  2. Disconnect and remove the negative battery.
    CAUTION After disconnecting the negative battery cable, wait 2 minutes for the driver-s/passenger-s air bag system capacitor to discharge before attempting to do any work around the steering column or instrument.
  3. Drain the cooling system into a clean container for reuse.
  4. Remove the instrument panel by performing the following procedure:
    1. Turn the steering wheel in the straight-ahead position.
    2. Remove the A-pillar trim from both sides of the vehicle.
    3. Remove the top cover from the instrument panel.
    4. Near the windshield line, remove the 4 instrument panel-to-chassis nuts.
    5. Remove the scuff plates from both front door sills.
    6. Remove the trim panels from both sides of the inner cowl.
    7. Remove the floor console.
    8. Remove the fuse cover from the junction box.
    9. Remove the instrument panel cluster bezel.
    10. Remove the steering column opening cover from the instrument panel.
    11. Remove the steering column bracket from the instrument panel column support bracket.
    12. Remove the lower steering column shroud cover-to-multifunction switch screw; then, unsnap both halves of the shroud cover from the steering column.
    13. Disconnect the instrument panel wiring harness connectors from the following steering column components:
      Both lower clock spring connector receptacles Left multifunction switch receptacle Right multifunction switch receptacle Both ignition switch receptacles Shifter interlock solenoid receptacle Sentry Key Immobilizer Module (SKIM) receptacle, if equipped
    14. Turn the ignition switch to ON position; then, release and remove the shifter interlock cable connector from the ignition lock housing receptacle.
    15. Turn the ignition switch to OFF position; this will prevent the steering wheel from turning and the loss of the clock spring centering following steering column removal.
    16. Remove the 4 steering column-to-instrument panel steering column bracket nuts.
    17. Remove the steering column from the instrument panel.
    18. Disconnect both side body wiring harness bulkhead connectors, the Ignition Off Draw (IOD) wiring harness connector and the fused wiring harness connector from the junction block connector receptacles.
    19. Disconnect the instrument panel wiring harness-to-floor console component connectors:
      Air bag control module connector receptacle Parking brake switch terminal Transmission shifter connector receptacle
    20. Remove the 2 instrument panel wiring harness-to-floor console ground terminals located behind the air bag control module.
    21. Disconnect the instrument panel wiring harness-to-floor console retainers.
    22. Remove the instrument panel-to-floor console bracket screws and the bracket.
    23. Remove the driver-s side floor duct-to-heater/air conditioning housing assembly screw and remove the duct.
    24. If equipped with a manual heating-air conditioning system, disconnect the vacuum harness connector from behind the driver-s side floor duct.
    25. Remove the instrument panel steering column support bracket-to-driver-s side of the heater/air conditioning housing assembly screw
    26. Remove the instrument panel steering column support bracket-to-intermediate bracket screw.
    27. Remove the instrument panel steering column support bracket-to-driver-s side cowl plenum panel nut.
    28. Remove the 2 instrument panel-to-driver-s side cowl side inner panel screws.
    29. Remove the instrument panel end cap.
    30. Remove the lower right center bezel from the instrument panel.
    31. At the passenger-s side cowl side inner panel, disconnect the instrument panel wiring harness bulkhead connector from the lower cavity of the inline connector.
    32. Near the right side cowl inner panel, located under the end of the instrument panel, disconnect both halves of the radio antenna coaxial cable connector.
    33. Disconnect the 2 instrument panel-to-heater/air conditioning assembly wiring harness connectors.
    34. At the passenger-s side, remove the 2 instrument panel structural duct-to-heater/air conditioning housing assembly screws.
    35. At the passenger-s side cowl side inner panel, remove the 2 instrument panel-to-passenger-s side cowl side inner panel screws.
    36. With the help of an assistant, lift the instrument panel from the vehicle.
  5. Discharge and recover the air conditioning system refrigerant.
  6. Disconnect the air conditioning system lines at the evaporator. Plug the openings to prevent contamination.
