Question: keyless entry system

sometimes the rke system works and some times it doesn't. It makes no difference if it's in the garage or out in the sun. The trunk opener inside the car sometimes works when the key fob doesn't and sometimes neither work, and sometimes they both work! Any help would be appreciated. Also, where might I find a wiring diaghram? Thanks again. Bill

It sounds like that your RKE module is defective. Most of the time, that has to be replaced by the dealer.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
