I have noticed my horn tone is sounding weaker and weaker. Along with not being as loud. Are the horns easy to replace?

 

It's got a pair of horns, a high and low tone that produce the classic Toyota beep. You probably had one of them die on you, they are located in the front bumper, and are very simple. U could get a set of own style replacements and swap em into your car with minimal issue. another option is to get a premium set from eBay. My original horns were getting weak so I picked up a nice set from eBay that are louder than OEM, and I replaced the alarm horn with a super loud option. The 3 cost less than $50 and were easy to install using the original brackets.
