One problem related to rear window wiper washer has been reported for the 1998 Mercury Mountaineer. The most recently reported issues are listed below.
I bought my vehicle about 3 years ago. It had 60,000 on the odometer. The back windshield wiper never worked, and does once in a while and the radio light never stays on. Once in a while it will show the station or the time. My drivers side door handle has always been loose. My engine light came on a year after I got it and it will not go off. It say egr flow insufficient and yet I have replaced all of those and had the computer reset. The passenger side door does not lock unless I lock it by hand and then you can't open it. The back seats sometimes lock and other times won't. My seat was recalled and I took it, and now it is broken. These cars are not made very well and I think we should get letters on the recalls. I haven't received but one letter and I took it immediately, but I see there have been other recalls and I wasn't notified. What should I do now?.
