I have a 2000 Sephia with about 92000 miles. I just got it. I am surprised how much I like this car. My shifter is all over the place. It shifts fine but the shifter is way to wobbly. I have to pay attention to what gear I'm in. Sometimes I shift into third thinking I'm in 5th. Also the signal light stalk. I have to hold it to make a right and the left, I have to cancel. The hi beams work and the signals work. Do I have to replace the entire switch? Thanks for your help.
