Why does my AC only work on low?
Odds are good that the fan switch may be at fault, but a more likely reason is that a blower motor resistor that controls the voltage going to the blower has packed it in, resulting in only one speed remaining operable — usually the highest speed, which you may not always need depending on the temp of the outside air.
How do you diagnose a bad blower motor switch?
A symptom that is a bit more obvious is a broken knob. It is not uncommon for the knobs on the blower motor switch to break or crack, as they are usually made out of plastic. If the knob breaks, the switch may still work, however, it may be difficult or impossible to change positions on the switch if it is broken.

In 2010, Toyota recalled nearly 375,000 Avalon models to fix this issue.

Why is the gas pedal stuck on my Toyota Avalon?
Worn Pedal Mechanism: When the sliding surface of the friction level becomes smooth during operation, the accelerator starts sticking. The gas pedal becomes harder to depress, slower to return, or stuck when partially depressed, resulting in unintended acceleration. This substantially increases the risk of an accident.
