Whenver I go somewhere and park, I have to unplug the battery cable to make the runner lights go off or the battery will be drained by the time i come out. Also, the ABS, servcie stability control, and the traction control light stays on at all time during operation. The temperature control for the heating and cooling system is not working at all. I use to be able to seen how hot/cool the temp was to adjust it, or if the air would be blowing from the top or at foot level and can't see this at all. I can, however, feel the heat or cool air, but can't see how to adjust it, because the light panel for this doesn't work anymore. I believe it might be the "computer module" but which one.
Lots of issues
seperate ones at that
runner lights have a sensor and relay
tracton control faults > ..ABS module or wheel /speed sensor faults
colling system >directional flap motors faulty
SOURCE: replace front brake pad 2003 toyota 4 runner
Diagram is unnecessry.
Pull both front wheels
Work one at a time leaving the other for reference
Find the retention spring ... its a paperclip thickness wire spring... dislodge center retention loop and undo from both ends which engage brake pad retention rods.
Pull the rods out
Pull the old pads out... laying everything on the ground
Use scrap wooden wedges to pry between the rotor and the caliper ...inside and out until the calipers are fully withdrawn. Use the new pads to measure if they are far enough back.
Note... the brake fluid will have dropped in the master cylinder over many months of wear... do not fill it. When the calipers are pushed back they will fill the reservoir again... one wheel at a time.
Be sure to identify the correct pad based on what you took out and what is on the other side (if you screwed up the layout)
Make sure to take the old antisqueek backing plate from the old pad and place it on the new pad. They don't use lubricant on these anymore.
Replace the pads... the retention rods... then the retention spring
Do the other side
Then progressively step on the brake peddle until full tension is felt
Check the master cylinder reservoir... probably needs no additional fluid.
New pads will register in existing ridges in each disc in no time at all.
You should check the discs to see if they need to be replaced during this operation...using some calipers

You either have a short some were or a vacum leak you need to, have your truck hooked up to a diagnostic machine to find out what is causing your problem.

You can check out what the trouble code is by pushing and holding the information button and the up arrow (right side of instrument cluster above the radio) until all the instrument clusters light. Press the information button (last) to enter test mode. I've had an error C1234, meaning Left rear wheel sensor fault. I found the problem to be a corroded connector under the chasis just under the rear left door about 2 feet in. I had to by-pass (replace 1 wire due to corrosion at the connector.

There is a heater core bypass pipe that runs from the block (under the manifold) to the bacl of theengine where you will see a flat rectangular "sheet metal" thing with a pipe coming out of it. The a rubber hose connects. You need to pull the top air plenums and intake to get to it. The p[ipe flange bolts to the block with silicone rtv as a sealant.

One of the "hall effect" sensors may have a damaged lead, or the sensor itself has failed.
