I installed new turn signal covers today and when i went to try them on they did not light up. the rears did but not the sides. and when i push the lever down to see if the blinked the turn signal lightin the cabin us stayed lit instead of flashing. I have no clue what went wrong. please help

I'd hazard something didnt get connected. If there's not enough of a load on the flasher, it won't blink.
Of course beyond that I'm useless...

Sounds like one of the bulbs is bad or not making contact. You said that when you put the lever down that they did not blink. Did you try to put the lever up and see if they blink. If they blink with the lever up , then there is a bulb loose on the left side. If they don't blink in either direction, then there is a loose connection some where. Good luck

Your right the bulbs where bad on both sides. Thanks
