There is obviously a problem with the trunk release solenoid in the trunk. You will have to do it the "old school" way and use the KEY to get the trunk open. Once you get it open, inspect the wiring conduit that runs between the body and the trunk lid. You will most likely find the problem there where the conduit bends back and forth each time the trunk is opened and closed.

Yes there can be, depending on which chip you get. Most chips do the same things which is advance the timing and add additional fuel to richen the mixture and adjust the injector pulse width for more output. In most vehicles the manufacture reduces the HP to meet emissions standards and increase efficiency of the car. Example a motor that makes 400 hp may be reduced to 300 for efficiency and fuel economy also for reliability and longevity. I wouldn't go with a no name chip for something as they usually don't do the research a larger company does and most name brand companies will give you the HP and still keep your motor running within normal tolerance without maxing out the vehicle and making it unsafe. Do your research and google the chips and see if any real people are using it and what they have to say. Ebay is a good company to get a deal and variety on the chip. Good luck.

Aren't you way out ahead of yourself there?

Your replacing electronic modules when you
haven't even diagnosed the issues

Do you have any knowledge what so ever about what
your referring to?

Have you hooked the car to a professional scan tool to look
at data pertaining to the various check lights?

HERE IS THE DIFINTION
Automatic transmission torque converter clutch stuck off.
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted
- Transmission internal mechanical problem

First check engine coolant level; if there is too little coolant in the reservoir, you should be alerted to the possibility that there could be a leak somewhere in your car's cooling system. Remove the reservoir cap and add coolant to the Full-Cold line, if a very short time after you refill the coolant reservoir the coolant level is low, there is a leak in your car's cooling system.

Engine coolant is used to heat the heater core and if the vehicle is low on coolant the heater core will stop working. The heater cannot produce heat due to the lack of heat from the engine coolant. Even if the engine is not over heating the coolant level can still be low.

Nest step, inspect Heater Control Valve that is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced. After the repair has been made refill the coolant level and recheck system.

Also, keep in mind that Blower Motor (electrical motor) is used to push air through the heater and air conditioner system, if the Blower Motor fails it will not force air through the system. Ground a test light lead to a good ground source, like a metal brace under the dash, seat mount bolt or under hood brace. Turn the key to the on position; check the fuse in the heater or blower motor fuse panel with a test light. Then lightly touch the service port at the top of the fuse on both sides. If the test light illuminates on both sides of the fuse, the fuse is okay and working properly. If the fuse lights the test light on one side it is blown and needs to be replaced.

Finally, if you are unsure of the location of the heater fuse consult a repair manual. If the fuse condition is OK, position the blower speed to the highest setting. Connect the ground end of the test light to a known ground source. Then probe both ground and power feed wires of the fan motor. The test light should illuminate on only one of the wires (fan motor failed). If the test light illuminates on both wires the ground source has shorted. If neither of the wires illuminate the power source is shorted.

Hope this clues helps; keep us updated.
