Question about 2004 Toyota MR2
I've recently bought a 2004 mr2 roadster and intermittently the car horn gives off a constant horn noise when I put key in ignition and when I take out again. Does anyone know what the cause of this is?
The private dealer I bought off recommends carrying out a series of steps on the battery to reset to factory settings (holding wires together etc), although Toyota/Friends/Family reckon not to touch this. Car is still under warranty with this dealer so I'm taking back to him to sort out. What's my best approach to ensure he fixes this permanently?

There is a major short somewhere,the hum you hear in the speaker
is the frequency of the DC electricity flowing through the speaker coils,do all four speakers hum or just one?Do you have a stock or aftermarket stereo?

The ST18x didn't come with a factory fitted alarm, so this is going to be more general.
Your alarm will have a manual disarm somewhere. If you have a small cylindrical device with your keyfob, there will be a receptacle somewhere near the drivers seat. You need to open the door and press the two items together. If not, you may have a button hidden somewhere around the place. In this case the procedure is usually to hold the button while you insert the ignition key and turn it to the ON position.
Some alarms have a small round key. If your alarm has one, or if your keys came with one and you didn't know what it was for, you can open the bonnet, pop a little cover on the alarm box (it will be bolted to the firewall, usually on the right hand side as you look at it) and turn it off until you can get it repaired, or get a new one fitted.
If none of this works and your alarm is an alarm only and not an immobiliser, you can simply open the bonnet and cut all the wires going into the alarm. If it is also an immobiliser, don't touch anything unless you're handy with a soldering iron and multimeter and have a few hours spare. (You would need to pull the cover down from under the steering wheel, then start taking electrical tape off the big block connector with thick wires, and then start rebuilding the wiring that's been chopped to make way for the immobiliser system on a colour-matching basis.)

hello gwolfson...from your explanation it sounds like the starter motor is turning but the bendix is not engaged. This happens over time and is caused by normal wear. A click or clicking noise would point to the starter solenoid. Don't wait until you hear a grinding noise to replace it, thats hard on the ring gear and flywheel. A NEW starter is recommended if you plan on keeping the car. If not, you can go with a rebuilt starter for around 65 dollars. Of course make sure the battery terminals are clean and secure as well as the solenoid terminals.
Good luck...i hope this helps and will fixya up.

I have a 95 camry 2.2 and it did the same thing. i helped jump a buddy's car then the horn started sounding. so i called the parts service for toyota they told me theres a switch under your dash, on the floor board, right above where the left is placed. there was a switch, he told me to flip it then my car started working no problem. that was about 1 yr 1/2 ago.

bank 1 will be whichever side cylinder 1 of your engine is and bank 2 will be the opposite side. It's named bank 1 and bank 2 so that no matter how the engine is laid out, bank 1 is always on the same side as cylinder 1. I cannot say whether the right hand or the left hand one will be bank 1 as I do not know where your cylinder 1 is. The garage should know
