Problem with the turn signals. Put new bulbs in driver's side work fine put in passenger side found a black wire not connected don't know where it goes now drivers side stays on and only the driver's door will lock with key.
Do you know when was the last time they worked?
Might be something amiss with the turn signal stalk, or the steering wheel.
Do all the locks work with the fob button or is it just the key that won't work (or do you mean the remote lock only locks the DS)?
When I changed the driver's side everything was fine than the passengers side went out changed it about 3 weeks later the alarm kept going off only way to stop it was putting key in ignition next morning windows were half down drivers signal won't blink but lights up the other nothing and key lock driver's door only
