Re: 1988 acccord turn signal acts like light is blown
Check the earth to the offending light unit. Clean all the relevant connections. You could also try fitting a temporary earth cable and watch for any improvement. If you find that there is improvement in the operation of the indicator/flasher make the temporaryearth cable permanent.

Front Flasher is separate from the rear at the firewall connector. Find out if you have good front flasher bulb and with a test light if there is a good + and - for the front flasher.
Now, for the blown fuse. I suspect there is a bad ground and the dome light and the flasher lights share the same ground.
Explaining: If it is when you turn on the right flasher(This is the bad ground circuit. The right flasher will take a shortcut to the dome light and probably the dome fuse is rated low. That will blow the dome fuse (Overcharge on the dome fuse). Could be why the front signals don't work at all. (Flasher ground problem).
Hope it helps.
Quite a puzzle you have that seems impossible, though such things weren't unusual in the old days of bimetal flasher units. The modern electronic flasher relay is designed to flash at a speed dependent on the amount of current drawn by the circuit so if a bulb goes out the speed doubles or thereabouts, giving the driver an indication something is wrong.
Broadly speaking the flasher unit will operate as it is designed within a current range so if there is too much current flowing or not enough it probably won't work at all.
The turn signal switch is usually a very reliable thing and as the left hand lamps light it is fair to assume it is working ok. If the switch is accessible it would be simple to measure the current being consumed by the circuit, which would be nearly 4 amps with the engine running at a fast idle. If it isn't then I suggest you revisit the lamp grounds and other connections.
My instinct is to suspect the hazard warning switch. It is often an unnecessarily complex switch and wiring arrangement and often responsible for turn signal malfunctions. Mostly operating the switch rapidly for a few minutes puts matters right, though if it doesn't I suggest you check the multiway connector behind the switch.
Good job, and good joe to you for solvin it! Now you'll remember that's a common indicator of a burnt out bulb. For some reason I can't explain, that is how a bad bulb acts on the flasher unit - by more rapid clicking (breaking contact inside the flasher relay at a quicker rate). It seems both the front and rear signal lights have to be working for the normal flasher rate ...well good.
No, no seperate system. Your problem is generally caused by a burned out bulb, bad ground at tail light. A bad flasher would affect both sides. Front and rear must be good. Ck flasher plug in. Good Luck
No,this is not normal,this normal when the emergency flashers are on,but not the turn signals.Check the bulbs(all of them)in the rear tail light assembleys.If you can not tell which bulbs are bad,replace them all.Does this vehicle have a trailer light plug?If it does,it could be in it.After the bulb replacement(look at bulbs in your hand to see if filiments are burned)replace the turn signal flasher.To find it turn key on,and left or right turn signal on,and listen,and feel for it under dash around the steering column.
With the vehicle In Park and the ignition on, swith the R/S signal on. Now , gwt out of the car and walk to back of car and inspect the R?R signal light . OK ? Now, do the same to the R?F signal light. One of them are not going to working correctly. Replace the defective bulb, or socket
Check the wiring in the front and back to lights for shorts to ground, if nothing is found replace the turn signal switch, be careful to disarm the airbag before doing any work on the column as the steering wheel must be pulled to replace the turn switch.
either the front or the rear turn signal bulb is blown, that is why the flash frequency is high. replace the bulb and the problem will be solved. best to replace both the front and rear turn signal bulbs. good luck.
