Hi Lilly,
Glad I was of some use to you. I bet you felt quite pleased being able to tell the mechanic where the switch was, I know I would!
It's nice to take your car to any mechanic armed with some info of the problem. gives you some idea of the work they are going to do and could save some people from being ripped off too.
I fyou get any problems in the furture, come back on this site to see if you can get more info, you never know you might end up impressing your mechanic again!
