I am wondering if you have a bad ground wire.
Each tail light/brake light had a separate ground wire, that is supposed to be hooked to the ground somewhere.
If it is bad, those lights will not work.
Your center light probably has a separate ground wire.
If you take an electrical meter, test the bulbs with a meter, then stick the meter's contacts inside the socket and press the brake pedal and see if the meter shows "juice".
Often a car wreck/fender bender can break or compromise the ground wire of which I spoke.
God bless your efforts.
Check your fuses. If OK check all the vacuum hoses for any loose connections or hose ends that may have hardened, if you find any that are hardened or have cracks in the ends, cut a piece off and re-insert. If still not working the electrical components (controls) will need to be checked.
sounds like it looses wheel sensor signal from the front left wheel, thinking its slipping. either a defective wheel sensor or loose connection somewhere on/in the wires between wheel sensor and control unit
If you have a multi-speaker setup like my 4Runner (also an 2005) Toyota uses a separate amplifier; i.e. not built into the the head unit (radio). The only home solution would be to clean the contacts where all the plugs connect. Back of the head unit, and the amplifier. If this doesn't fix it the amplifier probably has failed or the electronics in the head unit. Don't forget to disconnect the negative battery cable before doing any of this work, and make sure you have the security codes for the radio before you disconnect.
First find where it is coming from. Most likely from the valve covers. Just wear and tear on the components. I believe Toyota has adjustable valves. You'll have to remove the valve covers. The rockers arms will have a screw with a nut on the top of them. Loose the nut and adjust the screw down. This has to be done with each cylinder at top dead center. You will need feeler gauges. The gap is small. 3 to 7 thousandths. I don't have the exact numbers. The intake and exhaust valves are different measurements.
If i understand this correctly, this is normal. You need to top up the coolant regularly to the recommended level.
If you're referring to the heater in the car being intermittent this could have something to do with the coolant levels, your car has a OBD PORT and you can run a diagnostic yourself, there's several options on how to go about this. This could identify the cause.
check your radiator water level.
what body, CE, LE, XLE or XLE limited?
this car has 2 system.s (option) front and rear, are both bad?
or just the front? you said only rest of van.
the front has 2 options, manual and auto controls panel.
which one you have?
i see no cables. that leaves damper motors or vacuum servos.
a real tech tests the controls, first. if they are good
he look in the FSM for the damper motor tests.
its there. and he hot wires it and finds, bingo, its bad.
and replaces it. labor can hit hr on dash pulls. 8hrs. work.
find another mech.
the parts are sold at Toyota. look there , in the parts sections
see it, see those parts.? sure are... there.... need help looking ask.
the dampers are bad.
a real mech finds out which damper is bad
if its a motor , he buys a new damper motor at TOY. for $150
if its just a cable it fixes that...
it can be 3 things
1: control bad. even a blown fuse.
2: connection from 1 to 3
3: bad damper motor.
bad parts 4,5,6? (part 6, mode motor bad?)http://www.trademotion.com/parts/2005/Toyota/Sienna/CE?siteid=214001&vehicleid=185020&diagram=8530070
FIRE HIM!
CD disk bad. (audio disc bad or scratched)
or CD dont really support disk media format , is this a CDDA or MP3
some early MP3 disc drives do MP3 very poorly
or skips when you hit bumps in the road.
only that disc skips.?
