In some cases, the engine may not start at all. Replacing the faulty actuator with a genuine Toyota part like the 88606-35020 is the recommended solution to restore proper engine and air conditioning system performance.

To install the new actuator, you will need to follow the instructions in your vehicle's service manual or consult a certified mechanic. The installation process typically involves removing the old actuator, cleaning the area, and securing the new one in place. Once installed, the new actuator will allow your engine to idle steadily and your air conditioning system to function effectively, ensuring a more comfortable driving experience.
