Toyota Avalon (2004 - 2007) - fuse box diagram you find here https://www.autogenius.info/toyota-avalon-2004-2007-fuse-box-diagram/

This could get messy but I would start by removing the low pressure hose from the power steering pump (simple hose clamp) and attaching another hose to that so you can run it to a bucket then turn engine on and as its pouring out into bucket fill the reserve with new fluid shutting the engine off as it starts getting clear. Likely someone put the wrong type of fluid in there and contamination in the fluid or water condensation has frozen up in the lines so get the old stuff out and thats the easiest way withoiut making too much of a mess.

Could be the cable is seized and needs replacing. Try WD40 spray on all the moving parts. even in the ends of the cable.

1 - wiring, fuse, relay, bad connection, cable 2 - Motor assembly

check the continuity of the switch/s sounds faulty to me... you have checked every thing else....but it may very well be a relay... all power comes from the box for that type of stuff except the switch itself (switched power) which i think has its own line perhaps to its own fuse on your model ..not sure

There is no real advantage but you can get the bulbs off eBay. Buy ones that are direct plug bulb that fits in the same socket as the old bulbs and ones that do not require modifying the wiring with a resistor so the flasher will not blink to fast. To do the front and back and the backup and license plate lights expect to spend about $100.00 USD. I suggest you also buy spares, and don't buy the ones shipped from China, they are junk

It will be under the dash somewhere near the steering column. Turn on hazard blinker and feel under dash.

It could be the cog in the gearbox that is on the transducer or cable.

The MODE button (symbol of little man leaning back with an arrow pointing toward him) controls the air flow options.
You can push through 4 options
1. Panel flow(instrument panel and rear vents) man with an arrow pointing toward him.
2. Bi-Level (Floor/instrumental panel/rear vents) man with arrow pointing toward him and one pointing to the floor.
3.Floor (floor vents) man with arrow pointing to the floor.
4.Floor/Windshield(Just that) man with windshield symbol and arrow pointing toward floor.

I hope this helps!

Low idle can be caused by a dirty/contaminated throttle body, if the check engine light is not on, clean the inside of the throttle body with a can of intake air cleaner and a brush to remove the carbon deposits, disconnect the battery for a few minutes and drive it around for about 15 minuts.

hard to tell, but oil the mechanism and work the release back and forth, this may loosen it up. Don't slam it, could wreck the mechanism and is real hard on headlights and turn lights.

Check for the fuse or probably wires that got disconnected or cut.

that is located on bank 1 position 1 sensor heater failure =oxygen sensor heater element malfunction, eazy fix

Fix --you mean replace a part AFTER you test that part & the system it functions in !!! My guess would be something other than the button you push,maybe the trunk latch solenoid ALL vehicle issues have to be first learned,then tested, to just find a problem

Hi Mat, Have you checked the window motors? Check to see if power is getting to the switching control bank and then that there is a power output. The window motors can be checked with a 12 volt battery and two cables. During testing make sure to look after your fingers. Regards John

There is not much these days to tuning up a modern car. A lot of things are not adjustable anymore. You should not mess with the idle speed, engine timing, and emissions gear unless there is a problem indicated by the engine check light, or it does not pass the annual check for rod use. It boils down to changing the spark plugs, oil, coolant, etc at regular intervals.

Who did the work on the car? I would say things were replaced with no understanding of what was taking place, & nothing was tested to resolve the issue

I would want to check the oil pressure with a mechanical gauge or replace the switch next to verify the issue. It could be something electrical or the engine really could have low oil pressure.

Canada. seems (old post) the old previous owner , hacked it.or its bad. if car is in canada, the DRL module must work. if not fix it. see if its hacked first. (see cut wires to it?) ive seen ever hack possible to these. lots. check fuses first. check for hacks replace the module. or diagnose it with a voltmeter, easy see alldata.com most support the canada. versions. under the headlight sections. post this for others with DRL issues, few here. so...

The amp should have it's own inline fuse but if there is no sound it could also mean the radio has died or antenna is disconnected. Any stereo installation shop can find the problem without too much cost.
