I got a problem with my blinkers, everytime i put on my right signal the left signal comes on also.
Has any one ever had this problem? im stuck i checked all the connections and replace all the bulbs but still nothing.. Help me please!

okay it could be a short. the wire ansulator has been damged causing current to flow to both when u actuate your turn sinal and or u have a bad multi switch.

 

could it be a relay?

 

Yes, ICU failure has been known to exhibit itself through "odd" turn signal problems.

 

Your blinker fluid hoses are leaking. Replace the hoses and top em off with fresh blinker fluid. Be sure you ask for fresh, not recycled fluid.

Ok ok, real advice? Does the left side come on when you turn on the right side as well, or is it only when you do the right side? It's likely a bad turn signal switch.

I have the exact same problem, Ive replaced the blinker assembly with no results. All of my wiring has been checked, try the icu next ive read a few post about the icu causing this problem to. I just pulled my bulbs till I have time to fix it

 

no, it only occurs when i signal to the right.

 

Change your ICU, I just fixed mine buy swapping mine with one from a CRX at a local junk yard. If you don't know where its at I have pics

ICU pics



-Disconnect you negative battery cable.

-Locate your fuse panel and remove the two nuts securing it under your dash using a 10mm socket


-Gently pull your fuse panel forward, the ICU is on the rear left of the fuse panel (the gray box with a b on it).

-Remove the ICU by inserting a flat head under the fastener it should pop out with little effort. Install your junkyard find and try you lights

I drive a 91 civic si Hatch and used one off of a CRX so just look for one with matching number on the front of the ICU and you should be good

 

90% ICU 10%chance multi function switch. i would bet on the icu, without any diagnostic info.

 

thanks for the info, and the killer pics!
