I have a 99 civic and during the past months, it has been difficult to
start the car. So far, every time I can manage to start it after I turn

the key a few times. There is a pattern though. It is more difficult to

get it started in a hot or humid day. I guess this gets rid off the
possbility of bad starters or alternator and leaves the possibility of
bad connection or battery. My question is that whether batteries work
better in a hot/humid day or in a cold day. Also recently when I start
the car, I can hear something like clear clicking sound, not from the
engine or starter, but from the direction of glove compartment or
further or somewhere roughly that direction. And when there is that
clicking sound, I found it is much more difficult to start the car. And

yes, I also got a problem with my driver side door recently, months
after the difficult starting problem. I can't lock the dirver side
door. Even more wierd, occasionally, I can't open the door from inside
after driving for a while. I can open it from outside though. Seemed it

gets all the logic wrong (prohibit people from getting out other than
the other way). I don't know if the lock problem is connected to the
starting problem. Sometimes, I am thinking maybe there is a problem of
electric connection that get all things behavior strangely. Probably i
will start a separate thread to ask about the lock problem.
