20 Most Recent 2004 Toyota Corolla Questions & Answers


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,

Sounds like the door gasket or trunk gasket is not sealing.
You may have to take it to a body shop to find the problem.

Take it to AutoZ for free check up..they may be able to connect to their diagnostics tool to tell you what is triggering this...also perhaps you can find your access to the engine control module which will have a blinking LED which will tell you the error codes that will point you to what's wrong.

power to the ac compressor is the problem
could be the thermostat relay or what you have the ac set at
the ac will cycle if the cabin temp is at the setting
if you have climate control it will cycle as well

The problem sounds like intermittent power supply. There might be an inline fuse which sometimes does cause problems. Remove the radio and check the power line to see if there is such a fuse. If so, remove and clean it with a bit of sandpaper, put it all together and see if it helps.
Sorry, can't be more helpful.

No. If the compressor is bad no cold air at all. Sounds like the door that regulates the inside temperature might not be moving correctly. There's a chance that the cable is no longer connected to that door.

You don't fix just one, you replace them all at once and if the cam lobes are worn, the camshafts too.
