My 1998 CRV's left turn signal started flashing rapidly, the local auto parts guy suggested running the hazard lights to see if any were dimmer than the others, turned out the left front bulb was burned out, and as it has two filaments, it will still light, but dimmer than that on the other side. To change it I removed the screws along the left side of the front bumper cover, there are four to remove to get the left side to pull away from the body so I could get my hand in behind the socket, then just twist and pull the socket and bulb out.
Assembly in reverse order. I believe this is easier than pulling the splash shield. Just be gentle, and bend slowly to avoid cracking the cover
