Top 10 1990 Honda Accord Questions & Answers

My 1990 Honda Accord does this too.
When I wash it or when it rains. If I open the trunk/deck lid water flows out of the right rear tail light housing into the trunk.

Solution: get some rubber gasket sealant and apply under the lower gasket around the rear window on each side at the corners. Allow for drying time. Close the trunk and try some water if this doesn't work you will likely have to replace the rear window seal.

Best of luck.

Check with NAPA. They have a detailed layout of what you can buy to match up to OEM specs.

Your car probably has two fans at the radiator, one is for the coolant and the other is for the a/c condenser. Find out which one stays on after you turn off your car after a normal trip, this fan is good. Check the fan that did not run, you may have to connect 12v directly to the connector of the non working fan, if it won't run with a direct connection, the fan motor is bad, if the fan does run, then find the fan switch and test or replace it, you can find information on testing a the Autozone.com site.

Check 7.5 fuse (#8) inside the car by your left foot and check the 30 amp fuse in the engine compartment (according to your diagram on the inside of your fuse box lid).

You can replace the fan motor pretty easy but you'll want to unplug it and test it first by running an automotive battery to the plugs of the fan with 2 jumper wires. The fan is above the right foot of the passenger area. There are three 8mm screws to remove then it drops out. Careful with the wiring.
If your fan is still good, you'll have to consider removing your knob and switch assembly to see if something is unplugged in there. Good luck.

POSSIBLE RELAY

Castrol extended milage oil. Go to Autozone and they will set you up with the correct rating 5w-30,10w-30 or whatever their specs say for the season of the year, as well as an oil filter and washer for the drain plug.

TROUBLE CODES System Diagnosis READING CODES When the "Check Engine'' warning light on the dashboard comes on and stays on, it indicates a problem in the fuel injection/emissions system. Check the ECU for fault codes. On certain models, some codes will not trigger the check engine light; if driveability has suffered, check for stored fault codes. The most common error when using fault codes is to assume the indicated component has failed rather than checking the entire circuit. The presence of a trouble code means simply that the electrical circuit for the named component is not functioning properly. For example, a code for the oxygen sensor circuit does not automatically mean the oxygen sensor has failed. A wire terminal may simply be loose or corroded at the connector. When using diagnostic or fault codes, always remember that the entire circuit including the component must be checked carefully. On 1990-95 Accord (except V-6) and 1992-95 Prelude, the codes are read from the check engine light after the two-wire service connector has been jumpered. On Accords, the service connector is under the dash on the passenger side. On Preludes, it is located behind the center console. Codes 1 through 9 are indicated by a series of short flashes; two-digit codes use a long flash for the first digit followed by the appropriate number of short flashes. For example, Code 14 would be indicated by 1 long flash followed by 4 short flashes. Codes are separated by a pause between displays. Multiple codes are transmitted in an alternating pattern. For example, a code 3 and 14 would be displayed as 3 short flashes (for Code 3) followed by the separator pause, then 1 long flash and 4 short flashes (for Code 14).

1. Use a jumper wire to connect the two terminals of the service connector together.
2. Turn the ignition switch ON; the check engine light will display any stored codes by rhythmic flashing. NOTE: In the event that a code is encountered which is not on the chart, re-count the number of flashes. If the code is truly wrong, it will be necessary to swap the ECU for a known-good unit and recheck. Since this can be expensive, you may wish to bring the car to a reputable repair facility if no other cause of the failure can be found. This may save you the expense of purchasing an unnecessary part.
   
3. If no codes are displayed but a driveablity problem exits, testing of the system individual components is necessary to find the problem. If codes are displayed, follow the appropriate troubleshooting chart in this section. Fig. 10: Fault code chart for 1990-93 Accords

The main relay assembly is a small "box" located under the dash on the left side. It can be somewhat difficult to access. (You have to have double-jointed neck bones to see the thing...LOL)

About the only thing you didn't mention was the starter itself. You could have it tested. But before that, try to see if you have power on the small wire to starter solenoid on the starter, when key is held in cranking position. Pull the small wire off and check for power with a multimeter or a testlight while someone holds the key in crank. This is the signal wire from ignition switch that closes the elec. contacts inside solenoid so the starter gets full power from the battery to spin. (This wire also is in the circuit with the clutch switch and the starter relay.) If you have power on this wire in crank, it is very likely the starter is bad. If there is no power, check that circuit out. It is losing power somewhere from switch to starter solenoid. Good luck.
