I have a 2011 Xterra and have been going crazy with windshield washer problems. At first it would intermittently not activate (front or back) the sprayer motor (no motor sound, wipers work). This became worse until it stopped working altogether for the most part. Of course I checked the fuse even though it didn't sound like a fuse issue. I took things apart and got to the pump which worked fine when I applied 12 volts manually. Checking voltages at the pump, it looked like the switch was only working intermittently (12V sometimes, nothing other times). I took the switch off the driver column and checked it as per the service manual, and it was not making both of the connections it was supposed to make for activation. I traded out the switch with a new part from the dealer (which I checked against my old one, and it did make both connections, confirming the problem) and things worked great for a month, and now I'm back to the same exact problem. Right now it is working more often than not which makes diagnosis difficult, but I know I'm headed down the same path. Before I call Nissan and complain that I got another bad switch, are other people having the same problem? I searched the forums and someone mentioned a tech bulletin about these switches but I can't seem to find the bulletin or any other mention of it. I imagine if my 2011 had a problem and a new switch is failing too, other people must be having the same issue. Any info would be a huge help. Thanks.
