    Thank you, big help.. I had no idea what to do..

  • rallert Jul 14, 2010

    yes, what was I thinking, of course the release button in the center console.. Thanks

  • rallert Jul 14, 2010

    I disconnected all three switches and put the fuse back in and the hatch keeps right on opening.. uhmm.. any other ideas???

  • rallert Jul 14, 2010

    There are three control switches on the vehicle to open the hatch, one on each door and one in the center console.. I disconnected all three switches, put the fuse back in and it still popped open.... ?

  • rallert Jul 15, 2010

    That is what I did.. Had the same thought.. still pops..

  • rallert Jul 15, 2010

    That was next.. just wanted to hear your thoughts first.. I will get into that tomorrow and keep you posted.. Many Thanks!

It is likely the switch itself is connecting internally,causing the voltage to be applied to the lock mechanism. Try disconnecting the switch by removing the connector, this should stop it from cycling. Then test is with an ohm meter and check the resistance with the switch in an off state and on state. You should have zero ohms in the off state, if not, replace the switch.

    I will give that a try, is the switch located under the plastic cover right by the lock itself?



    Thanks,

    You should have a rear hatch switch in driver area to activate, No?

  • GetMeOttaHere Jul 14, 2010

    You have a bad ground somewhere in this circuit. You say three switches, do you mean the rear hatch connection also? If you disconnect the power lead at the hatch, this has to stop it from opening. Then an inspection of the ground connection(s) should be verified. All the switches control the ground (negative) side of this circuit.

  • GetMeOttaHere Jul 15, 2010

    Put the fuse in and leave it in, disconnect each switch one at a time,and see if the opening stops when a switch is disconnected. This should isolate the defective switch or at least the side of the circuit from where to start diagonsis.

  • GetMeOttaHere Jul 15, 2010

    Then we need to consentrate on the lock mechanism itself. Have you been able to access the lock?

  • GetMeOttaHere Jul 15, 2010

    No problem....keep me posted.

Replacing rear hatch struts on 2002 santa fe


open the hatch,, get a 2x4 or something that will hold the weight of the hatch up, prop it in place against the floor and the hatch itself, so its solid and won't come off under pressure so once you remove the strut it doesn't come crashing down on you, they have a bunch of different ends on them, when you buy the replacements make sure the end caps are the same, some are held in place by a nut with a bolt that attaches to a bracket on the opposite side , and some have screws at each end that go right into the sheet metal of the car . with the hatch open,, you should have very little play left in the strut itself,, but still use care in the removal of the first side of it,, you may have to push it in a little to get it to release, again, this depends on the mounting harware that your vehicle has for attachments. don't think that replacing one side at a time will hold the hatch open,, use the board or broomstick if you have to,, to support the door

My 88 corvette won't go into 4th gear, a mechanic told me the transmission would have to be dropped and synched. How many hours of labor does it take to do this?


You will have to remove the trans & replace ALL the Sychros
& possibly selective snap rings

I would do it yourself--after all it is a corvette

They are for people who do ALL their own work

THE HATCH LID DASH OPEN STAYS ON EVEN WHEN THE HATCH IS CLOSED HOW DO I ADJUST THIS?


Sounds like you have a bad fuse? If you leave it this way it will drain your battery. use your manual that came with your car to figure out which fuse handles that area and remove and replace it. If you dont have a manual, remove them one by one until you no longer get the error then you know you have found the right one and replace it.
