well me and dad went to change the spark plugs and the first one on the right side was horrible. This is what happened. he went to put the socket on it and it wouldnt turn and it ended up getting stuck on the plug. we think its hitting something . Also, the left side turning signals dont work. The lights work (braking and parking and such) but doesnt blink. Any suggestions to what to check first? Any help would be appricated.
