Air condition not working

Does the heater work ? blower motor pushes air out of the vent's ? A/C compressor doesn't engage ? I'm try to figure out what you have going on there . completely dead on dash panel ? Two fuse in the central junction box F2.14 10 amp an F2.20 10 amp these power the climate control panel . Relay one has nothing to do with it . If the fuse's are good you need a new control panel .

Following wiring from the blower motor back to see if there is a short somewhere in that part of the harness, also check the relay.

Hi, the resistor is screwed to the side of the blower housing behind the glove box. See procedure below to replace the resistor. You don't have to complete all steps in the procedure. just work your way to the point that you can unscrew the resistor. Please let me know if you have questions, and thanks for using FixYa.

1990-93 Accord

See Figures 2, 3 and 4

1. Disconnect the negative battery cable. If so equipped, disable the Supplemental Restraint System (SRS).
2. Remove the glove box.
3. Remove the glove box frame (lower support)

Fig. Fig. 2: Remove the glove box and frame

1. If not equipped with air conditioning:
   1. Remove the three screws and remove the heater duct.
   2. Remove the blower mounting nuts. Unplug the wiring from the blower motor, resistor and recirculation control motor, then remove the blower assembly.
   
   
2. If equipped with air conditioning:
   1. Lift the carpet in the passenger compartment. Remove the side cover (kick panel).
   2. Remove the control unit bracket nuts; unplug the five connectors and remove the control unit bracket.
   3. Remove the retaining band, then remove the blower lower covers. Do not break the tabs on the lower covers.
   4. Remove the retaining nuts and remove the blower assembly.

If you mean the climate control blower motor, it's usually under the dash on the passenger side on Hondas.

   4. Remove the retaining nuts and remove the blower assembly. Fig. 3: Air conditioned models require the removal of the control unit. Handle it carefully
      Fig. 4: Remove the lower covers from the blower unit
      To install:
      
6. Install the blower unit and tighten the retaining nuts.
7. On air conditioned vehicles:
   1. Install the lower covers and the retaining band.
   2. Install the control unit bracket and carefully engage the wiring connectors to their proper location.
   3. Install the kick panel and reposition the carpet.
8. Connect the wiring to the blower assembly. For non-air conditioned vehicles, install the air duct and tighten the screws.
9. Install the glove box frame and install the glove box. Note that some of trim on the frame is held with 2-sided tape; replace the tape when reassembling as necessary.
10. If applicable, enable the SRS.
11. Connect the negative battery cable.

1988-91 Prelude

1. Disconnect the negative battery cable.
2. Remove the glove box and frame (lower support).
3. Remove the 4 screws and remove the heater duct. Fig. 5: The glove box and frame are secured by several small screws
   
   
4. Remove the 3 mounting bolts.
5. Unplug the wiring connectors from the blower motor, resistor and recirculation controller. Remove the blower motor assembly.
6. Reinstall in reverse order. Make certain the blower mating surfaces are tightly sealed.

Per your description, I believe you may have a blower fan relay that is stuck closed.
Remove the relay from the under-hood fuse center and see if the fan stops.
If it does stop, put the relay in slowly and see if you here the relay "click" and the fan come back on.
Let me know.
Regards,

Yes its the blower motor resistor.

More then likley theres some trash or something in it, or possibly the motor itself is on it's way out. There not that bad to pull out of that body car, just pull it out and see what you can see.

The blower motor is under the glove compartment

You can replace the resistor on your own. Please find a detailed diagram which would guide you to do it.

BlowerMotor Relay is Located On Driver Side in Engine Compartment and is the LARGE Relay in center of box CLOSEST to you If you are Standing On the Driver side of Car This is A Culpret, Also the "BLOWER MOTOR RESISTOR" also can Cause What You describe.
I HAVE PICTERS AND Manual Info But need Email Address to send as FixYa Wont Exept this Type of Files

Blower Unit Components Replacement

Note these items when overhauling the blower unit:


The recirculation control motor, the power transistor ), the blower motor (C), and the dust and pollen filters (D) can be replaced without removing the blower unit.

• Before reassembly, make sure that the recirculation control linkage and doors move smoothly.
• After reassembly, make sure the recirculation control motor runs smoothly.

Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.

yes, all blower motors have them to control their speed, High, medium, low.. etc. I earn nothing by helping you, but my rating, a fixya rating and I will walk you through this

most probable cause.. blower motor resister. & vaccuum leak to control blend doors or electrical actuator for blen door
