Where is the turn signal relay located in the Highlander?
2 Answers
The turn signal relay in the Highlander is located inside the fuse box under the dashboard cover. The turn signal is an important indicator light that activates when the vehicle is turning to alert surrounding vehicles and pedestrians. The turn signal bulb uses a xenon tube, controlled by a microcontroller circuit, with alternating left-right flashing for continuous operation. The Highlander's body dimensions are 4890mm in length, 1925mm in width, and 1720mm in height, with a wheelbase of 2790mm. The Highlander features front-wheel drive, with a MacPherson strut front suspension and a double-wishbone independent rear suspension, utilizing a unibody construction.
As a car owner, I've experienced turn signal issues with my Highlander. The relay is usually located in the fuse box under the hood, specifically on the left side in front of the driver's seat. If you open the hood and find the black box, there should be labels indicating the turn signal relay or similar names. That's where I found it in my older Highlander model - just open the cover and you'll see the position diagram. When replacing it yourself, first disconnect the negative battery terminal to avoid short circuit risks, then gently pull out the old relay with small pliers and install the new matching model you purchased. Don't try to save money by buying off-brand parts. Regular inspection of these small components can prevent sudden failures - for example, non-functioning turn signals can easily cause rear-end collision risks. Making sure all lights work properly before driving is a fundamental habit.
