The blower motor is located directly below the passanger glove box on the right. Its a round flat plate with 2 small screws holding it in place. All you need is a screwdriver and a pair of wire cutters (the wire cutters totally depend on whether the replacement is factory or not.) Simply unblot the existing part and replace it with the new part. If you have purchased an aftermarket part you will need to cut and attach the factory harness pigtail to your motor. Also the replacement part I purchased didn't come with the blower wheel, so I had to remove the old one and place it on the new motor. Works like a charm! Easy install and best of all....I have air after 2 years without!!

SOURCE: Air Bag Sensor light on & horn not working

Without knowing exactly what the air bag code is, coupled with the known fact that the horn is inoperative, my opinion for a viable solution is to replace the spiral cable or, as commonly called, the "clockspring". This device is the main wiring connection between the steering wheel and the wiring harness. If the circuit(s) open,due to a failure of the spiral cable, the air bag light will be on, the horn will not work,and , if you have a steering wheel Cruise control, it too may be inoperative. Best solution: replace the clockspring. Best advice: Get the airbag DTC's checked, and if you have an open in the driver side air bag circuit, the clockspring is def the culprit. Given that you had chassis work, your DTC just may be the front crash sensor, and the horn may just be unplugged, or bad, This is the best I can do for you, given the info that you have provided,
Hope this helps, and thanks for choosing FixYa.

SOURCE: toyota tacoma 2003 check engine light is

If the car still runs then the problem is not major but may develop into one if unchecked. The sensors in the engine may have detected problems and should be stored in its ECU. If you have a scanner have it connected to the diagnostics it should give you a clue on what to check out.

SOURCE: 2003 parking bulb toyota tacoma

OK, I just fixed mine. The unit pulls out. You have to get a screwdiriver, wrap it with a cloth so it doesn't scratch the paint, then gently wedge the entire unit out. When it pops out, you'll see the clips that keep it in place. You might think its breaking when you pull it out, but trust me this is how you do. Just be gentle with it. After you get the unit out, simply take the socket out and replace the bulb. I did it in five minutes.

2000 Toyota Tacoma Horn Relay location needs replacing


1- The HORN fuse is located in the fuse panel on the driver's side under the engine hood. Of course, if it is "blown" replace with the SAME size or smaller and retest the horn.
2- Verify the horn itself (isolated) using one wire attached to the Main Battery + (POSITIVE) to the spade terminal on the horn. The horn can be accessed after carefully unclipping the fasteners connecting the front grill to the radiator area- just be careful- work slowly. The horn is naturally grounded to the vehicle frame.
3- If the horn sounds with the direct bypass voltage test move to the cab. when you depress the combo horn pad/airbag listen carefully for the relay behind the left under-dash area. If you hear it, then the relay is "closing" but it still may be bad or the voltage from the horn relay is not getting to the horn. I would replace the relay. However, there may still be a wiring problem to the horn.
4- The Horn Relay for the '00 Toyota Tacoma V6 4WD I worked on was BEHIND the cabin fuse panel on the far left driver's side (oh thanks guys). I went to the trouble of pulling down this relay/fuse block- it was not exactly "easy" but I am not a beginner and had the tools and my curiosity and sleuthness prevailed. If the new relay does not fix this issue my next step is to replace the wire from that relay to the horn. Again, not easy but not impossible either. Take you time, use the right tools and materials & check your work. The only other option was mentioned earlier- drop in a new momentary switch (lighted?) into the dash and run a new wire. I would NOT use switched power so it can be used without the vehicle running... I think it is safer. This is a view of the interior panel dropped down. One of the relays can be seen- the grey cube with a empty relay socket just to the right. Why they put these here- is anyone's guess.

Horn/lights on 2002 Toyota Tacoma


Rewire your horn from the steering wheel to the horn. Its not difficult, I can't tell you how to take the steering wheel apart but you can get a Haynes Repair Manual. It'll have all you need and more. You can use speaker wire, split it in two. Run one cable from the positive in the battery to the horn switch in the steering wheel. Another from the switch to the horn. You have a short somewhere, to me is easier just to run new wires than to find the short-circuit. Make sure when you run the cables through the firewall you run through a grommet so it does not get damaged by metal. Before anything check your headlight wires that they are not touching the horn.
