These MR2s came from the factory with a subwoofer and 6 speakers...if your subwoofer has been removed and the system tampered with, you may just have to run a new power wire from your ignition switch and a new ground to your new unit. Just make sure that you wire it to the correct posts on the ignition switch.

Also, do not ground it to the battery...the electric powersteering will make a buzzing in the stereo anyway since it is not shielded, but if you ground the unit to your battery it will make it much worse. Ground your unit to the floor or some other metal surface close to your stereo. Hope this helps...I had the same problem when I bought my 1991 MR2. Good Luck!

My turn signal quit working i checked the fuses and the bulbs and put a new turn signal switch in it and the turn signals still aren't working what else could it be


Usually when you get at the turn switch, you can use a jumper wire to bypass the turn switch and make the turn signals dance. If they won't work with the jumper, the problem isn't the turn switch. Maybe a problem with flasher or wiring issue in steering column?

Did you check for voltage at the turn fuse? Goes hot with the key on. Use a test light to check for voltage.

I have a 1992 Toyota MR2, one evening I cam out to go get a movie, went to start the car and all that happened was the starter started clicking rapidly. I turned the ignition switch off and the starter...


This sound like a more common issue than we in the mr2 community would like to see. The cars are old and the ground wires tend to wear out. But normally the gas pedal cable becomes the place were it grounds out and start a fire. get a cheap ground wire kit for the engine compartment as well as put a few on the battery. Also check existing ground wires. Hope this helps!

1992caravan turn signals, low beams, and heater motor do notwork


A) Faulty turn signal switch or circuit.
B) Broken dimmer switch or poor electrical connection.Could be relay also.
C) Unplug the electrical connector at the motor and use fused jumper wires to connect the fan motor directly to the battery. If the fan still doesn't work replace the motor. If fan works could be your relay.

Turn signals dont work headlights dont dim heater fan doesnt work


Did all these problems happen all at one time?? If so you may have a bad body ground. Try running a electrical wire from the (-) negative side of the battery to the body and see if this works. Be sure this wire is to a place with no paint as low voltage electricity will not flow through paint.
A). If not try replacing the turn signal flasher for the turn signal problem. This is usually the culprit and it's easiest and cheapest to replace. The turn signal flasher will be found under the driver side dash next to the hazard flasher. Turn the hazard flasher one to locate it. If you want try swapping the turn signal flasher with the hazard flasher to see if this fixes it. They are the same style flasher.
If this doesn't work you may a faulty turn signal switch or some wiring issues.
B). It could as simple as the head lights bulbs need to be replaced, it's rare but I have seen when both bulbs blew at or near the same time. If your able check the voltage at the head sockets.
C). Could be a bad blower motor or switch. I'm not sure if these models have a resistor block or not. The resister block controls the electrical current going to blower motor which controls the speed of the blower fan.
