Hi,

I have dodge caravan 99. I have starting problem in the winter time. When I am starting some time it's start but some time it show the click sound, but if you try couple times, some time it's start. I check the battery, battery is OK.

Please tell me how to figure out this problem.

Thanks

What you are describing is usually caused by a weak battery. Or by poor connections, either of the battery cables. Check both ends of both cable to make certain they are clean and tight.
If they are not corroded or loose, have the starter eletrical draw tested. It may be the starter is consuming too much from the battery.
