My left turn signal doesn’t work in the back & blinks fast in the front & the right one cuts in & out. Is this an easy/cheap fix I hope???

 

maybe, maybe not. sounds like you have a bulb out maybe even a bad ground. could be a poor connection in the light housing. best thing to do is check your bulbs, make sure theyre good and the proper bulb and replace if needed

 

The bulb was changed but that didn’t fix it
