Unknown red light/button in 2004 4Runner SR5

Do you have a air bag light lit on the instrument cluster ? I ask this because , if the air bag light is lit , could be a clock spring problem . I know ,what the heck is this guy talking about . You have a air bag on the steering wheel ,the horn button is on the steering wheel . The clock spring is located under the steering wheel , in the top of the steering coulmn . It has flat wire tape in side that allows the steering wheel to be turned full left to full right , keeping the horn , air bag , an any other button's on the steering wheel connected electricly to the vehicle. Plus there is a relay , when you push the horn button it energizes the relay turning on the horns. Watch these videos , will explain a little better .

to bleed power steering, with front wheels off ground slightly with front wheels pointing straight ahead.engine off. remove power steering filler cap.add power steering until fluid level stop dropping,wait couple minutes and wait, add fluid until level stay at full cold mark on power steering cap dip stick. dont over fill.when fluid level stop dropping, start vechicle,let it idle few minutes. see if fluid level drop if so add more fluid full cold mark.then turn steering all the way to left and right with out hitting a stop.turn steering wheel several times, then turn front wheels pointing forward check power steering fluid level.if power steering fluid level stop dropping air should be out of system, if steering turning wheel dont turn smoothly and power steering fluid look light tan color air getting in the system.check all power steering lines to rack and power steering pump for leaks.be sure you replaced all the power steering lines with new o rings if not you will get a leak.if you find a leak, you need to fix the leak and bleed system again.dont drive vechicle if your steering dont feel right,have vechicle towed to a garage.

check if the fuses are already busted. fuses are located in your kick panel, just below your steering wheel

I am currently have the alarm going off on my 06 Tundra 7 and tried the recommendation above but didn't get rid of problem. I don't have keyless remote. There is a red light button on lower left of steering wheel & button underneath the dashboard under the steering column. Has anyone had a problem like mine that can give me specific instructions that will work for my. 2006 Tundra

As a general rule the power steering pump will be located on the front left side of the engine. (think Left/Right as though you were seated behind the steering wheel.) The pumps are usually painted black and will be about six to eight inches in diameter with a cap on the top that you can remove to check the fluid level.

You have a wire that is rubbed bear inside the steering column, pull the covers and inspect the harness. Disconnect the battery negative cable for 10 minutes before you start work to disarm the Airbags

i believe the audi uses two relays for the turn signals and hazzard lights so it would appear the turn relay has failed. it should be located under the dash near the steer column.... seems to me me they have some shielding under the dash so it may be hard to get to.

have you tried moving the wheel

You do not use the buttons.

You have to use the Steering Wheel remote Control
