My trunk will not open. When I take off battery cable and replace, it opens once. Is there an easy fix? relay etc?


When the rear compartment lid release switch is pushed, the rear compartment lid release signal circuit to the body control module (BCM) is grounded. BCM then grounds the coil side of the trunk release relay through the trunk release relay control circuit. With this voltage is applied to the rear compartment lid release actuator, opening the rear compartment.
Rear Compartment Lid Release Relay
  1. Ignition OFF, disconnect the trunk relay.
  2. Test for 65-90 ohms of resistance between terminals 85 and 86.
  3. ?‡'
    If the resistance is not within the specified range, replace the trunk relay.

  4. Test for infinite resistance between the following terminals:
  5. ?€¢
    30 and 86


    ?€¢
    30 and 87


    ?€¢
    30 and 85


    ?€¢
    85 and 87


    ?‡'
    If less than infinite resistance, replace the relay.

  6. Install a 10-amp fused jumper wire between relay terminal 85 and 12 volts. Install a jumper wire between relay terminal 86 and ground. Measure for less than 2 ohms of resistance between terminals 30 and 87.
?‡'
If greater than 2 ohms, replace the relay.


Rear Compartment Lid Release Relay Malfunction

  1. Ignition OFF, disconnect the trunk relay.
  2. Verify that a test lamp illuminates between the coil side B+ circuit of the trunk relay and ground.
  3. ?‡'
    If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal and the B+ circuit fuse is open, test the voltage control circuit for a short to ground. If the circuit tests normal, test or replace the trunk relay.

  4. Verify that a test lamp illuminates between the switch side B+ circuit of the trunk relay and ground.
  5. ?‡'
    If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

  6. Disconnect the harness connector at the rear compartment lid latch.
  7. Ignition OFF, test for less than 5 ohm of resistance between the rear compartment lid latch ground circuit and ground.
  8. ?‡'
    If greater than the specifed range, test the ground circuit for an open/high resistance.

  9. Connect a test lamp between the trunk release relay control circuit and the coil side B+ circuit of the trunk relay.
  10. Command the trunk release solenoid ON and OFF with a scan tool.
  11. ?‡'
    If the test lamp remains ON all the time, test the control circuit for a short to ground. If the circuit tests normal, replace the BCM.


    ?‡'
    If the test lamp remains OFF all the time, test the control circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM.

  12. Connect the harness connector at the rear compartment lid latch.
  13. Connect a 3-amp fused jumper wire between the switch side B+ circuit of the trunk relay and the voltage control circuit of the lid latch. Verify that the lid latch activates.
  14. ?‡'
    If the lid latch does not activate, test the control circuit for an open/high resistance. If the circuit tests normal, test or replace the rear compartment lid latch.

  15. If all circuits test normal, test or replace the trunk relay.
Component Testing
Rear Compartment Lid Release Switch
  1. Ignition OFF, disconnect the harness connector at the rear compartment lid release switch.
  2. Test for infinite resistance between the trunk release switch supply voltage and ground terminals with the switch in the open position.
  3. ?‡'
    If less than infinite resistance, replace the rear compartment lid release switch.

  4. Test for less than 2 ohms of resistance between the trunk release switch supply voltage and ground terminals with the switch in the closed position.
  5. ?‡'
    If greater than 2 ohms, replace the rear compartment lid release switch.

  6. Test for infinite resistance between each terminal and the lid release switch housing/case.
?‡'
If less than infinite resistance, replace the rear compartment lid release switch.


Could be the relay , could be the switch , could be a problem with the BCM !

There is a relay in the rear fuse block for the trunk release. marked trunk relay #36. It is marked on the under side of the lid. If you knew how they worked you could open it by jumping pin 30 to pin 87 in fuse box. on the side of the relay is a diagram of what pins are what . This system uses an electronic control module called ( the BCM ) body control module .When you push the inside release button , that sends a signal to the BCM ,then the BCM activates the relay opening the trunk . Well that won't help ,you won't believe where the fuse box is ! Fuse Block - Rear
In the rear compartment, behind the left wheel well. You could jump the wire at the BCM that goes to the relay. Can't you pull down one of the rear seats to gain access ?

you need to remove the inner door panel, this is done by removing the screws that hold it in places, ( sometimes under plastic caps, that cover the screw, and sometimes inside the door pull handle ( that hole you pull the door shut with ) also,, along the bottom and sides there are clips Just grab the bottom of the door and pull out on it, work your way along the bottom and up both sides, to get the panel off you need to lift it up off the window edge,, also, inside the door release lever there is probably a screw, once removed, you need to turn the handle slightly and feed it back through the hole, you can get the retaining cover around the edge of the handle, by slipping a flat head screw driver inside next to the hinged end of the handle , and pop it outwards towards you , that gets you in the door, a plastic water shield covers the inside of the door,, Just peel it out of the way ,, you'll see a hole that contains the door lock cylinder, the arms to it are held on with little plastic clips,, and they get very brittle,, pop those off, you will see the items, (either a screw or bolt) that hold the cylinder in place, remove that

How do I remove the back bumper from a 2006 hyundai tuscon?


take help of the following steps to remove rear bumper on ur tucson.

Open the trunk of your vehicle.
  1. Unscrew all the screws on the inside plastic trim that covers your bumper to trunk connection.
  2. Pry the plastic piece out with a flathead screwdriver. You will expose the bolts that attach the rear bumper to the trunk.
  3. Unscrew the bolts connecting to the inside of your rear bumper. There should be four bolts.
  4. Unscrew the two to four screws connecting to your bumper from the inside of the rear wheel tire wells. These screws are on the area of the tire well that is closet to the bumper.
  5. Slide under the rear of your car. Use a flathead screwdriver to pop the plastic rivets out of place along the underside of the rear bumper. There should be four to six rivets.

  6. Squat behind your car and firmly pull the bumper off. There will popping plastic sounds, this is the pop-in-place plastic rivets that are the last pieces that hold your rear bumper in place.

How do I check the radiator flued?


the radiator cap is in the engine compartment, not at the radiator. The mr2 has a very strange radiator set up, because of the rear engine. when the engine is cold, open the radiator cap. If you see fluid, you're probably ok. However, I would recommend if you are worried about it, to bleed the system of air. The procedure is in the owner's manual, but there are 3 air bleeding valves. You need some hose (usually found in the front trunk behind the shroud and spare tire, clear plastic flexible tubing. One valve is on the drivers side radiator top, one is by the heater, and one is on the engine/transmission (the one with the hose already going to your overflow tank). with the car off, you can open these valves to let air out of the system if it gets trapped in those high points.

Let me know if you have trouble.

A host of problems with my '87 MR2


looks like you have a lot of problems due to poor maintenance. look for a salvage yard around your area. get an AFM, distributor, and coil/ingiter and swap each component one at a time to identify the culprit (I suspect coil). replace all suspect vacuum hoses (again one at a time). Check engine light can be diagnosed to point out your specific problem so there should be no guess work on this. inspect wiring that connects to the coolant sensor. Also check electrical connections (potitve battery post and all chasis ground). air pockets in the cooling system also causes idling problems so make sure you bleed it completely. also inspect air/fuel filter, plugs and plug wires and distributor cap and rotor. replace as neccessary.

good luck

Trunk leak


Check for defective spot welds around the plastic inserts on the left and right sides of the trunk. If the spot welds burnt through the metal, there will be holes were water can get in. Use some JB Marine Weld to seal up any holes or cracks in the sheet metal. Also, check the rubber drain holes under those inserts, that are in the sheet metal of the car, to make sure they are not blocked with road dirt. Also, check the weather stripping on the outside of the car, adjacent to the trunk. If the rubber and chrome trim weather stripping is pulling out (on the exterior of the rear quarter panel), then water will leak through the little plastic attaching screws and into the trunk beneath the plastic containers on the left and right front sides of the trunk.
