The drains are plugged or the drain tube is disconnected on the passengers side allowing water to run down the passenger side pillar or out the disconnected tube and the bcm is there in behind kick panel. Body control module. Try drying it out with forced air and maybe even heat. If no luck after that try hooking battery cable for a bit to reset as well. If nothing try the dealer and mentioned. The bcm and may be the problem. I have an 06 h3 and have had troubles with the sunroof drains before. I joined a drum and learned the cure.

SOURCE: The power battery light stay on when I turn off the engine off

I had the same problem, Youl need to do one of the following, Change the eginition module or change the driver side control pannael the one for the window/locks (if you can crank the key a bit when its turned off it may help sometimes) sometimes a bit of rain comes in the window and down into the control (locks/window switch) and shorts it out. Trust me I spent time and money to figure out its that or your egnition module. EBAY for the parts it will only cost $100

the next time you do get it out,take the key to any hardwear store that makes key's,have them make a dupe if they have a blank,so you have a copy,then have them run your key on there wire brush to smoth all the sharp edges,if it still sticks, then replace the ignition sylinder. good luck

SOURCE: This morning when I attempted

Hello:Try this procedure: turn key on, turn to start, let key come back to on wait ten minutes, turn key off wait 10 seconds turn key back on wait 10 minutes. turn key off wait 10 seconds turn key back on wait 10 minutes turn key off wait 10 seconds NOW try and start. In addition you might try tapping on switch assembly while trying to start. There is not any way to disable passlock. You might try having the engine control system codes read

What or where are the timing marks for 2002 hyandai accent 1.6

The timing marks allow the engine to be correctly timed . It depends on what you are trying to do . If you are just trying to time the engine with a timing light .Then the mark that you would look for would be on the harmonic balancer thats the lower pully that that fits over the front of the crank shaft there will be a corasponding mark on the vehicle next to the pully that has marks in degrees that you can line up with the pulley as it turns and you use a timing light attached to #1 cylinder and ground to see this alignment the light flashes as the engine turns and lights the point up at the correct time to see it . Then you adjust the disturbutor to control where the mark moves so you can make the alignment move by turning the shaft . If you are talking about timing marks on the timing chain gears then there is a dot on each gear upper and lower and they need to be aligned in the middle so the lower gear the dot or mark is at the top of the gear and the upper or cam gear is faceing down but this alignment needs to be a perfect alignment if its off by 1 tooth you will know it the vehicle will not run vary good and back fire a lot

Please help dome lite will not go off battery goes dead!!! Anyone know how to fix this roblem

Check the plastic dome light switch which is located inside the driver door frame near the front of the vehicle. There should be a plastic buttom which gets depressed when the door goes shut, thus turning off the dome light. Sometimes, these buttons can get broken or damaged for numerous reasons and stick in, hence permanent dome light.

Service vehicle soon lite 2003 chev. malibu 6cyl. 60,000 mi.

Ignition switch is a solid culprit. the contacts get worn out or even "stretched " due to "Forced" turning of the key. You know the part where you try to turn the key past the stop point.
