I have a 99 RR 4.6 and the wipers have never been proper since I bought her. At the moment I am getting nothing whatsoever.
I changed fuse and the relays (R1 & R8) but I am still getting zero. At first the fronts worked in high speed and would not park and not nothing. The rear seem to be working OK. My mechanic said it could be in the BeMC (Yikies that sounds expensive) What is the best way to troubleshoot? Anyone else ever had this issue?

 

Well the BeMC controls everything. I think i have heard prices of about $1000.00 but not sure. Signs of it going out are the One-Touch Windows losing programming or other weird electrical quirks. I would say go to an LR dealership and have them scan it
