SOURCE: windsheild washer not working in toyota avalon 02

Looks like the washer motor has failed. Remove the lower plactic trim under the washer bottle & check to see if the connector is plugged in to the motor. Also check to see if there is power to the motor with the switch depressed. If you have power, you need a washer motor. Common failure if the washer fluid freezes once. Ice gets inside the motor & expands, breaking the internal housing and ruins the motor.

There isn't a fuse for this. Like you said dash board control module. The Instrument panel (IP) is a computer, it is fed by the ECM (engine control module) You could have a loose contact with the plug in the IP since you have lost everything. But I wouldn't rule out that the IP has gone bad.

The ABS light on my 2002 Toyota Avalon is on,speedometer's not working & the transmission shifts poorly. Our mechanic said it needs an ABS control module. Would the ABS module cause those symptoms?


I would have a scanner hooked up and look at the signal from the Vehicle speed sensor before replacing the outrageously expensive ABS unit.

Error Code P0351 for a 2005 Toyota Avalon


Possible causes
Faulty Ignition Coil 1
Ignition Coil 1 harness is open or shorted
Ignition Coil 1 circuit poor electrical connection
Faulty Engine Control Module (ECM)

What does this mean? When is the code detected? Each ignition circuit is continuously monitored by the Engine Control Module (ECM). The test fails when the ECM does not receive a valid pulse signal from the ignition coil. Possible symptoms Engine Light ON (or Service Engine Soon Warning Light) Lack/Loss of Power Engine may be harder to start Engine hesitation Rough engine idle P0351 TOYOTA Description: The ignition system on the vehicle uses individual ignition coils for each cylinder. The Engine Control Module (ECM) controls each ignition coil operation. The ECM sends a ON/OFF signal to energize the ignition coil to create a spark at the spark plug when a spark is required at the cylinder.

2002 Toyota Avalon intermittent setting on wipers not working. In that setting the wipers stay on continuosly and when setting the wipers to the off setting they stay where ever the blades are at the time...


The problem is a broken part in the module which is inside the wiper motor. As far as I know, the part is not available, and you must replace the entire wiper motor to repair the problem

I have a 2006 avalon with code po500. no speedometer, abs light stays on. dealer changed abs unit with no help. wheel sensors are good. changed speed sensor on trans. where to look now


Hello Hotrod.

It may be a bad speedometer head/instrument panel if everything else has been checked/replaced
It certainly would be the item I would look into at my shop.

On many Toyota's the signal from the speed sensor goes to the instrument cluster first and then it is changed to a digital signal by the cluster and sent to the ECM. I wonder if they checked the speed signal with a scan tool. This would access the signal at the ECM and should prove this.
This signal would also be sent to the ABS module so it may be the next step.

I hope this helps you diagnose the problem.
Thank you for using FixYa.

Transmission just started slipping and clunking at 107,000 miles.


Well, I had the same problem and after changing the good as new looking pink fluid in a " do not change under normal driving conditions" transmission, having the ECM reprogrammed and taking the car by AAMCO transmissions I took a lead and bought an updated and new ECM and had it reprogrammed at the dealer. The shift bucking stopped and as long as you don't see out of the ordinary wear indicated by exessive flakes in the transmission pan the mechanicals of the trans are toyota reliable... it was just a badly designed ECM. I bought my new ECM for $800 online from a toyota car dealer in Virgina.
