Hello. The only way I solved the wiper problem from them starting by themselves was to pull the wiper fuse out. Don't know any other way to fix it. This brings me to another problem. Tonight when I was driving along the speedo starting going up and down then the green s light started flashing, about 5 minutes later the orange engine light came on. I managed to get the codes out, the orange light was code 17 and the green light was code 4. Both those codes indicated the speed sensor but I only replaced it about 2 years ago. How long are they supposed to last? With the codes I mentioned would the speed sensor be the problem? Thanks
