Heat/AC Blower Motor and Cabin Filter Question
1) Did 19992 Accord EX with AC come with a cabin filter?If yes,where is it?
2)Can the blower motor be direct wired to check the blower motor to make sure it's in working condition without damaging it?I am replacing the resistor.

1) I don't think so but, I am not 100% sure.
2) Yes. Either take the blower motor out and take it to the battery or use the battery from your cordless drill. Also, it doesn't matter which terminal on the connector you apply voltage and ground as the motor will spin both ways without damage.

Re: Heat/AC Blower Motor and Cabin Filter Question
1. There is no cabin filter on a 92.
2. Have you tried turning on the blower with the switch in position 5? When the blower switch is in position 5, all resistors are bypassed and the blower motor should run at full speed.
As long as the wiring and the blower motor relay is good, when the ignition switch is in RUN, power/voltage (+) will already be supplied to the blower motor. It just needs the ground source (-) (which would come via the blower switch in the heater control panel).
a. If the blower did not run when the switch was in position 5, one way to see if the motor runs is to: Disconnect the motor's 2P brown connector, attach one end of a spare piece of wire to terminal/cavity 1 (Blu/Red wire) and plugged it back in. Then ground the other end of the spare piece of wire to body ground; the motor should run with the ignition in RUN, as long as the wiring and the blower motor relay is good
b. An alternative way to see if the motor runs is to: Disconnect the 5P brown connector (which connects between the blower motor resistors and motor wiring) and attach a spare piece of wire to female cavity 2 (Blue/Red wire). (You can leave the 5P brown connector unplugged.) Then ground the other end of the spare piece of wire to body ground; the motor should run with the ignition in RUN.
