one turn signal is blinking fast? Options

[DSToyo]

when i bought my car, the passanger side blinkers (front & back) blink twice as fast and half as bright, while the drivers side blinks and is bright normal
-i have replaced the bulbs in the front and it didn't do anything at all
-the wires don't look tampered or destroyed at all
i just want to get them to blink the same again and don't really know how to, ive read some other posts on topics like this but dont really get it.

i guess im going to change the bulb in the back to see if that helps
thanks for any help/suggestions

tried/looked at everything...everything blinks, turned the flashers on and the same problem is happening there too

could it be a relay...how do i replace if so (i know nothing about relays or wireing)
-thanks
