Top 10 2004 Toyota Corolla Questions & Answers

I have a corolla 2003 and I had the same problem. I turned the key to the left and the lock turned left, engaging the valet parking mechanism. I could not turn the key to the right and could not get access to the trunk because the lever next to the driver seat was disengaged.
The way I solved this problem is as follow:on the back driver seat I pulled the back seat forward to leave an opening and snick my arm in the trunck. Then I grabbed the cable used to latch the seat and I pulled forward, i.e. toward the front of the car. The cable is connectred to the trunck so that it can be disconnected easily if pulled towards the front. If you pull towards the back it will remain attached to the trunck. So grab the cable an pull towards the front, and it will release itself. Since the cable is flexible, you can pull it out of the trunk from the same the opening you put your arm, and then disenagage the driver back seat. Fold forward the back seat and get into the trunk and use the lever in the latch of the trunck to open it. The turnk will open.

If the lock does not turn, you need to disconnect the lock from the mechanism, so that the driver seat lever can start working again. To do this, and with the trunk open, remove the cover holded by nine plastic pins. Do not break the pins. After removing the cover, you will see the lock holded by two nuts. Remove the nuts with a rachet. The lock will be loose, and disconnect the lever that connects the lock to the latch. At this point the driver seat lever will start working again. Close the trunk and verify that the driver seat lever opens the trunk. Now you can open and close the trunk , and have time to call the dealer for a new lock.
Good luck.

To loosen and remove the drive belt on a 2004 Toyota 1.4L engine you simply use a wrench and pull up on the spring-loaded tensioner.
You should be aware, however, that if you are experiencing problems with belt squeal or rattling noise, there is a Technical Service Bulletin (TSB) for your vehicle that provides information for an updated tensioner assembly.

check for clogged cabin air filter, located behind the glove box. See owners manual for directions on how to remove the filter.

I've now fixed two of these units and they both had identical problem and solution.
The problem was an intermitant fault, that after a random time, would result in a noticable snap and a failure of the sound system both radio and cd player.
Solution:- In both cases this is diy fixable with just some screwdrivers and a soldering iron.
First remove unit; this is done by unsnapping the two trims that house the face air vents this then exposes the fixing screws 2 at the rear 2 at the front, remove screws then theclimate control facia ,this allows the unit to come out far enough to unplug all connections both to the hazards ect and the radio unit.
Once out, remove the radio lid and the facia housing the controls, this just snaps out of retainers that you systematically release with a screwdriver. remove side supports marked L & R then this exposes a number of screws to remove including a small side panel that allows you to unplug the cd interface. Note ; it is not necassary to remove the cd player from facia plate. remove two screws exposed by removing control panel then remove ribbon from socket that supports lcd screen. This should then allow you to gently ease the radio unit clear of the facia plate and cd. Once clear remove all screws retaining back plate and pcb and lift pcb clear of case. Now viwed from the top and front you will see a heat sink that supports 4 big transisters , re-solder all legs of these transisters (3 legs each) this has cured the problem twice for me now. Assembly is reverse of reassembly plug in and check out those sounds,

firstly it could be that the check engine light is mal-functioning or not. why not drive it as they said and if after that its still on get back to us.

P0741 deals with internal transmission torque converter slip. A proper scan tool that is capable of reading the sensor's data inside the transmission would show the slipping torque converter and the fluid temperature.
It is critical to know exactly what conditions are present when the code stores. If the codes were not erased, they could be old codes in it's history.
Go back to the transmission shop or where you had the work done on replacing the TCC solenoid and have them read and clear the codes history. As mentioned, they could be old codes that is being read prior to your repairs.
Thank you for using Fixya and good luck, Have a shop verify line pressure, and provided no valves in the TCC hydraulic circuit are worn, replace the torque converter. Also, Lubegard Shudder Fix will at least fix this for awhile. Or try a transmission flush by a shop that uses BG brand products.

I would check the AC clutch relay. It has a bad habit of going out. It is located in the fuse box under the hood next to the battery. It is the smaller rectangular relay nearest to the negative battery post. It is labeled M/G CLT. You can swap out a similar relay and see if it fixes the problem. New relays can be purchased from Rockauto.com for $11

Hope this helps you ??

You'll need to set off the alarm for a few seconds.
then, look under the dash area for a button or, a toggle
switch. When you locate it, turn on the ignition
key, press and hold in the button (little
spring loaded micro button, red or black possibly)
until the alarm chirps 1 time. This should over ride
the system, and only the keyless entry part,
if installed, would still be operating.
The LED (light emiting diode) light in the dash
should also go on solid.

At this point. the alarm would have reset.
If this had a starter kill relay installed,
it would now be opened, and the engine would
turn over when tried. This is override/reset.
