Further clarification on the O2 sensor location: It is in the exhaust pipe, under the center of the car, on top of the pipe, just aft of the oil filter.

Difficult to describe, but I will give it a try.
Inside the driver's side fender, close to the front of the car, there is a bracket that is held in place by one bolt, but which has a short horizontal bar as part of it which has two large clips encircling two cylinderical devices which have wires clipped into them at the bottoms. The one closest to the front (radiator) is the compressor clutch relay. The other one is the condenser fan relay.
Hope this helps you find it.

SOURCE: how to remove starter from 1998 honda accord

Detach the cable from the negative terminal of the battery. Caution: If you have an anti-theft radio, make sure you have the activation code before disconnecting the battery.

Remove the battery and battery tray from the engine compartment (remove the battery first, then remove the bolts for the battery tray and remove it.).

Remove the lower radiator hose and the wiring harness from the starter bracket. Make sure they are positioned out of the way.

Clearly label, then disconnect the wires from the terminals on the starter motor solenoid (the smaller cylinder attached to the starter). Disconnect any clips securing the wiring to the starter.

Remove the mounting bolts (two) and detach the starter (pull it gently out of its housing).

Reverse this procedure for installation.

Hope this is of help to you.

the blower motor is located behind and under the glove box. its held to the blower housing by three screws. remove the three screws and the motor will slide down and towards you. to test the motor. apply power to the yelllow/black wire and ground to the blue/red wire. the motor should run. if not you prob have a faulty power resistor.
