Left side speakers quit playing in my 96 Tacoma. is there a fuse for this

Gauge fuse 10A in left kick panel power the control coil of the blower relay
Alt 80A fuse in the underhood fuse box powers the contacts of the "heater" relay
Once the heater relay contacts close, power flows to the "heater fuse" 40A in the underhood fuse box.
From that fuse, power goes directly to the the blower motor.

So check all three fuses AND the relay

Check front signal bulbs.

sounds like body control module

Hi, here are your factory wire colors/functions. Aftermarket stereos have a common set of colors, which should be in your installation diagram. The process is simplified if you purchase a wiring adapter for your vehicle. These are available for under $10 at most WALMARTs and auto parts stores or about any place that sells car stereos. In either case, I recommend you solder the connections or at least use crimp terminals. If you have any more questions, please let me know--I've done a lot of stereo installations.

:o( you're going to have to pull the radio out to see what they did. They probably added a wire to an inappropriate circuit to power the new radio or amp. I will paste your factory wiring colors below. If you now have an extra wire, that is the likely culprit. Trace it to see where they hooked it in. If it isn't going to the the fuse box and using an extra slot, make it so by connecting it to the cold side of the fuse and put an approprite size fuse in. To determine the fuse size to use, you can compare the wire gage to other cold side wires and use a fuse the same size as you see being used for similar gage wires. Let me know if you have more questions.

Recheck your wire connections, good luck.

Thank you for using Fixya

The filter is on drivers side under the intake...

I don't think it is a fuse.
The warning chimes for this vehicle come through the radio and are play to the speakers and if I remember correctly the chimes play to the left front speaker.
I would check for a faulty speaker or wiring to the speaker.

1. air filter dirty. 2. bad engine ground. 3. fuel filter 4. loose connection in ignition system. 5.faulty idle control system.

left of steering column almost behind fuse box way at the top you have to stick your head under there with a flash light to see it but it's there.
