1991 Honda Accord Park Lights

Hi batmanwho,

The speedometer malfunctioning is most probably due to a faulty Vehicle Speed Sensor located on transaxle housing below the thermostat housing. This would also cause the D4 light ( S mode light for some ) to blink while driving. Sometimes the Check engine light would show asa well.

As to the light, is your vehicle equipped with Daytime Running Lights?

Yes my vehicle has daytime running lights.

Are the dash illumination, interior switches illumination and rear taillights working when the front park lights do not work?

Does front park lights turn off immediately when the engine is started?

Just to clear something up! All my park lights don't work..My interior and dash work fine. My park lights usually turn off when I start and/or put the car in drive. It varies.

The dash and interior illuminations are connected to the park lights under the same circuit so if the interior lights are functioning whereas the exterior lights are not, you have a bad connection that is intermittently faling due to vibrations or jerks.

This is not going to be easy to check and you should start with checking connectors at relayboxes and connectors for contaminations and looseness.

The question I have now is if there is a bad connection, why does the park light always come on when I turn the engine off with the key in the on position? Could it be the DRL module? Thanks!

Sorry I missed out 1 item previously. It is the integrated control unit plugged into the underdash fusebox. It is related to the park lights.

The DRL control module is not linked to the park lights.
