Sounds like water intrusion into one or more Wheel Speed Sensors. You need to have it scanned and see which sensors are dropping out when they get wet. Then replace them or have them replaced.

You don't say if the wear is on the front or the rear, but I suspect it is on the front. I would take it someone other than the dealer, that specializes in front ends. If it is the front, there is certainly a problem there.

The seats are not the same. the controls will be on the wrong sides. If you insist on doing this yourself then unplug the wire harness connectors on each seat and remove the 4 bolts holding the seat rail to the floor. There will be plastic covers on the bolts that just pop off.

A component of the airbag system is failing. If you are steering when it flashes it could be the clock spring in the steering wheel. When this light is on you will not have airbags in an accident. only a scanner can pull this info.

is it afs light if so its to adjust your headlight positions.

What does it say in the drivers handbook? Look behind the headlamp under the hood for star style plastic knobs for manual adjustment. Does it have electric adjustment? Talk to a dealer?

Ticking noise coming from the manifold? There are two types of manifold....1. Instake manifold and exhaust manifold. Please indentify and apply as needed.

Intake manifold
1. Double check the nuts and bolts around the intake manifold if you worked on it and had it serviced.
2. Spark plugs loose. Yes!! I've seen this before and it comes the rear of the manifold..very confusing.
3. Check your valves and have them adjusted. (This will require a trained and qulified mechanic).
4. Check your motor oil and power steering pump fluid.

Exhaust manifold
1. Check for loose nuts and bolts.
2. Check the O2 sensors connections...some models have 2-3. They are the sensors sticking into the pipes.
3. Your catalytic converter may have a defect. If possible, remove it and shake it to determine failure. (I've seen and experienced the so called honeycomb inside it breakign apart.)
4. Check the exhaust manifold heat shield if applicable.

1. Check for loosed hoses/clamps/leaks?
2. IF your hoses are secured with stock easy access clamps...switch them to worm clamps.
3. IT may be the reservoir leaking.
4. Is the color water/liquid identical with your coolant color?
5. Check the hood weather strip, it may seap water from the front of the hood.
