My car - 2003 Honda Accord EX V6 (coupe) - Ever since I had work done in September (invoice attached) my left turn signal started blinking rapidly. The bulbs are fine. I took it back to the shop and they replaced the turn signal relay. Now it ONLY blinks rapidly when I have either/both the parking lights or headlights on. When the other lights are off, the left turn signal works normally. The work that was done, as seen in the invoice attached, had something to do with replacing the negative terminal ground strap. As soon as I got the car back, the left turn signal was not working properly. Shop insists the two are unrelated, but seriously? Any thoughts or advice would be most appreciated! Thank you!
